pH run off is 6.0-6.3 (last time)
I have been giving the seedling enough nitrogen Im pretty sure.
is the clawing too high or too low? and I only have two plants under Metal Halide at the moment. The Large Northern Lights clone, and the northern Lights seedling.
Thought I was giving enough potassium, anything I should do to give them more? Up the nutes?

Maybe the larger plant is root bound? it's only in a 3 gal, I have a 5 gal, but I was thinking of just taking alot of clones from the larger plant and placing it outside, which sounds like a better idea (around here temps get up to 105-109 during summer, but very humid too most of the time)

How often should you change the pot of the plant , is there any recommendation on when or how to judge when the plant's ready


Oh yeah, top picture of Northern Lights seedling

Well, I dug the hole outside for the plant, Im going to go buy some peat moss to put the cuttings in and hope I get alot of them to live, for some reason, I haven't been able to keep my clones alive (this is the first time Ive ever had failed clones, Idk what happend)

I've probably taken about 20 cuttings, and all of them made it, I took 5 cuttings this time, only one made it (or is trying to make it, not sure if it even did, and I dont wanna pull it up to see if it rooted)

Heres what I did

I cleaned my scissors with ISO alcohol, rinsed with water dried off with a dust cloth.

I got a bowl of R.O. water,

I got the rooting hormone ready (put it in a small container where I can just stick the bottom of the cutting in, but its not the original bottle , just pour out a little into another container as I don't wanna contaminate the rooting hormone bottle )

I would put the bowl of water up to where I was going to cut the plant, I tried to cut most of them at an angle, leaving them with a kind of pointed tip, then I scraped off some of the outer layer of the plant, dip it water , roll it in rooting hormone,

Then I place it in red plastic cups full of moist peat moss, with a hole already pressed in there (so the rooting hormone doesn't get rubbed off the plant if I were to just stick it in the peat with no pre-made hole.)

I spray them with water to keep them moist and let them asborb water through their leaves (since they don't have roots) every 2-4 hours, I keep them warm.

And yet, most of my last batch died, Kinda weird, IMO....

Does it matter if I'm taking cuttings off of the top of the plant, or the bottom of the plant?
I picked most of them out of the middle last time, I don't know if it makes a difference, but most of the time I just take them from the very bottom, but this is also a plant much larger than Ive ever had before, so, I dont know.

Anywho, hope everything is going well with everyone's plants.

and my Ph run off was 6.3 by the way.

(and theres just two plants Im working with at the moment really, my Northern Lights clone, and My Northern Lights seedling(Which is the healthy one out of the two) I want to take alot of cuttings and throw the larger one outside because I know it still had a long time to go, Im just wondering what to do about the heat when it comes summer, lol, I put a big piece of wood about 3-4 feet high sticking out of the ground to try and shade my plant during summer when it hits high noon (no shadows, or very little) Wondering what I should do about outdoor temps, or will they be able to handle it? )

Ive got a few sativa plants outside that Im not really paying attention to, if they grow they grow, if they die, no biggie, they were free seeds from my uncle, Pure Power plant, I wasn't much of a fan of it, If it does grow Ill prob either use it for cooking foods or just rolling joints.

That NL looks good mate.

Rule of thumb for pot size's is 1 gal is about 1 months root growth. I would repot her if you can see roots around the drainage holes under the pots.

I dont think thats the problem with her though. It wouldnt be your nutes lacking anything I dont think. All I can think of is pH mate, most plant problems come back to the pH, but I know you say it's at a good range. AE will probabaly chime in, maybe he'll be more help.
 
I harvested my lady this morning at 53 days flower. The buds look amazing and full of crystal, just couldnt get that to come out in the pics because of the rain. I'll have some dry shots next week :)

Here are the final shots. Im glad she's done after 6 months of hard and stressfull labour :)

When you use peat moss for cuttings etc, do you add dolomite lime or garden lime? If not, were you aware just how acidic peat moss actually is? You should not root cuttings or grow cannabis using peat moss that hasn't had lime of some sort added to raise the pH. Otherwise you will run into all sorts of problems!

I personally would not measure run off pH, as in my own experience it's too unreliable an indication of what's going on with the pH in the medium itself, especially if you're doing it with plain tapwater. If you do a 2:1 extraction and measure the pH this way, you'll find it can be quite different from the run off pH. If you want to measure the pH of the medium, then you would take say 100ml medium in a flask (or cup) and fill with distilled water up to the 200ml mark. After shaking it up and allowing it to settle, you can then measure the pH with a digital pH meter. However, I can tell you now without needing to do any pH testing whatsoever that peat moss on it's own is way too acidic.

Taking a cutting from just about any part of the plant, whether it be top or bottom, usually tends to root quite readily Cutting at the node is desirable since that's where the highest concentration of plant hormones is.

Instead of using peat moss on it's own, I suggest you mix it 50/50 with sharp sand (after adding the right amount of dolomite lime) since cuttings root better in a more free-draining medium than pure peat moss offers.

Also you really should keep the cuttings in a propagator when they're rooting to maintain high relative humidity levels to root the cuttings readily. Normally 85% RH is about right. That high an RH is hard to achieve without a propagator, unless you've got some sort of automatic misting system for example.

Pot up when you see roots through the drainage holes in the bottom. I would pot up in this order - small 5cm pot ---> 1L pot ---> 3L pot --->6L pot. You shouldn't really need a larger pot than 6L unless you're vegging for longer than 6 weeks.

Either that or 1L ---> 3L ---> 11L ---> 20L (you get the general idea I'm sure). Potting on is like driving through the gears in a car and will always improve your results and so is worth doing. If you can't be bothered with so many stages, at least go from a small pot or peat puck etc. into a 5" pot and then into your final pot.

Well done mate, I bet you're glad, especially after someone actually discovered it!!

Did you actually harvest it at night?

Have you had a chance to trim it yet?

I can't wait to see what it looks like when it's been dried and cured. Keep us updated :)

As you can see in the photo, I've finally built the greenhouse! I've decided growing in it is too risky, so I'm only planning on growing the plants in the early stages after germinating indoors, after which I'll transfer the plants to my guerrilla spot. Also shown in the other photo is one of my plants, the Blue Widow seedling! I'm just about to put all the rest in 5" pots containing my amazing '511 mix' that works mind-blowingly well.

^Nice, allotments are cool. I reckon they're the sort of quintessentially English thing that the Aussies/Yanks are going to be totally confused by as well. Runner beans for AE breakfast, lunch and dinner from now on then, eh?
 
^ I'm more of a tomato fan really. Black, yellow, round, sausage-shaped, tiny, huge, you name it, I've got it.

I've got all the types of plants I'm going to grow separated into the 4 crop rotation groups already - legumes, root veg, tender crops and brassicas. The problem was I never had enough room in my garden to grow even a tenth of all the different types of seeds I've got, so now I can go mad and just grow everything I've ever wanted to grow (bar cannabis).

I'm so unbelievably lucky to get this allotment, as the waiting list is usually 5 years minimum in my area (it's a disgrace really). Apparently some poor guy broke his back or something and ended up having to give away his 3 allotments (why he had 3 I do not know), so I just got lucky. I also think it had something to do with me pestering them for it for months.
 
hi guys, just a quick question, my girl has 2 half wks left, should i increase the feed i mean i feed her every 3 days so could i give her just water between the nute feed? Thanks
 
IMO you should be starting to flush her now, stop feeding altogether and just give her plenty of water.

yea as yerg said start flushing her maybe give her 1 more week.You want as little fertrz n nutes in your plant at harvest tI'me as possible.
Not sure if this is a proven method or something but I've been told when nearing harvest to start giving plants less and less water resulting in them pulling all the nutrients out of the leaves and on the last 2-3 days give no water....Someone please correct me if I'm wrong..

^I've not heard that, but tapering down the water will certainly make the plant drier and thus reduce curing time. I wouldn't have thought that an annual plant like cannabis would behave like that, but I really don't know that much about botany/horticulture.
 
Not to be rude, but depriving a plant of water won't help it IME. To flush out the nutrients just water with plain non-pH adjusted water (you should not adjust the pH even in a hydro system in this stage when flushing).

Mind you there are different approaches to growing, however I don't see any reason it will help. If you want to reduce drying time the best way is to reduce the relative humidity when drying the buds, although I wouldn't recommend this myself.

flushing

so wen i start flushing her, how often shall i do it? Do i stick to my 4ltrs every 3 days, or do i water less but more often, i understand the concept of getting rid of all the nutes and chemicals, but im a bit unsure of the best way to do it,
 
Just water as you normally would to keep it healthy, but use plain non-pH-adjusted luke warm tapwater. Don't add any nutrients and this should work.

There is a better alternative to flushing in the normal way however.
 
For the final flush before chop goahead try to use 2-3 times the ammount of water that your pot can hold. So for example if she's in a 5 gal feed her up to 15 litre's of water. There is some conflicting info on the web about how much you should water and how often. IMO you want to completely cancel out any chance of there being any ferts left in your buds when you harvest.

Hey AE mate, thanks alot :) Im very happy the effort is over, now just to wait for these buds to dry. I havnt really done a proper trim. I just took all her main floppy fan leaves off, im going to do a final mtrim when she's dry up :)

thanks alot guys, she is in a 8gal pot so thats alot of water eh but if thats your advice then thats what ill do, i remember AE mentioned about pop corn buds, the small weak ones at the bottom and inside that dont get any light, and there fore wont be any good or of any use, i can see what he meant, the question i have is, is it possible to cut these off of her now as they will just be wasted when she gets the chop, or will it stress her or cause any problems? She is doing really well, i have added the pk 13/14 for one wk as directed so on her next feed ill just water her with plain warm water as AE advised, {im just wondering what the benefit of the water being warm is?} im sure AE will be able to explain it for me,
she has alot of nice sized buds with loads of lovely thc crystals forming and they are nice and sticky. i am very happy with the way this girl has turned out, {this being only my second grow and my first girl turning into a boy} i have learnt so much and improved my growing skills 100 fold and its due to you guys with all the advice and help you all so freely give so thanks to you all.
so is there any thing i need to be aware of at this stage? as i have never been this far before and i dont want to get complacent and miss something that might hurt or stress my girl, any advice pls guys, a fellow grower told me that i could cut some of the fan leaves down a bit to let more light onto parts that a covered by the leaves, he said as long as i dont cut more than half of the leaf off, and cut each leaf that is on the leaf i cut, ie some of the fan leaves have got 7 or 8 leaves on them so hes saying to cut all 7 or 8 not just some, is this correct and can i do it? as i said i dont want to do any thing that might cause a prob, thanks guys
 
I think the warm water is to reduce stress. I always water with luke warm water at any given time. Cold water can shock the roots of many a plants, so i don't see how cannabis is different. This is just my personal opinion and i have no proof of this....but it makes sense. Certainly not going to hurt anywho! :)
