Unfortunatly I am unable to post any pics, but I'll give an outline of the problem, pretty simple really....Some of the veg growth[bottom leaves mostly] are losing color.fading for lack of a better word. The healthy vibrant darkish green has gone to a light green, and a bit of drooping...Mom said it could be either under or over watering, I am just watching and taking notes. Opinions and/or advice please=D p.s.-these are not the little circular leaves that are the very first to sprout, these are regular serrated MJ leaves---just wanted to clarify that...:)
 
More nitrogen ! Simple really. It sounds like N deficiency and also while you are at it, add some Calcium like botanicare Calplex or Calmag or something similar. Calcium for veg along with N-rich fertilizer and Magnesium in flower along with a PK-rich fertilizer.
 
thanks everyone...Ya know, ANoob Growers StartUp Kit would be a great item.I have one small pot with a few sprouts[approx 4 weeks??}, tap water[no ph test]and no nutes. A crude and primitive grow for sure, but I will have the stuff I need very soon. Can nanyone direct me to a start up list??I imagine PH important. I did purchase some miracle grow pottting mix, with self releasing nutes, supposed to be good for 6 monthes`
 
You should check out the grower's forums over at icmag.com

I don't have the time to send you in the right direction for everything you've asked, but I can give you the things that need to change so you can go off and do your research on those. Maybe someone here will be nice enough to help get you started (I'm on holiday this weekend, can be better help on Monday).

  • You need to seperate all the seedling into their own pot
  • Miracle Grow anything is bad for marijuana, and the soil you have is useless (unless you want to be smoking the nutes in your soil). Extended release anything is not approiate for marijuana.
  • Tap water needs to sit overnight to let the chlorine off-gas, then it must be re-oxygenated somehow (airstone or vigorous agitation).
  • The PH of the water, nutes, and soil is important, and giving it anything without knowing the PH is undesirable. It's important to control this, for without proper PH management you'll likely end up killing them one day.

Hope you get things straightened out, and have some great buds on the way! Unfortunately, I doubt that this grow will be a success for you unless you're ready to take in a whole lot of information an put it to use quickly.
 
whatever the actual issue is I would put money on a pH problem. Most nutrient deficiencies are not caused by a lack of nutrients in the soil, but rather a pH imbalance. When the pH is to high or low it will lock out nutrients (often this leads to toxic levels because growers will continue to throw nutrients at their plants not realizing the levels were fine to begin with, the plants were simply unable to use them).

Most tap water is somewhat alkaline, meaning greater than 7.0 (neutral). MJ does best with I believe 6.5-6.9, like carl said, check out icmag or another grow forum. These resources specialize in growing and are full of expert growers who are more than happy to give advice to a new guy. My personal favorite is growkind.com, smaller forum but has a great FAQ section and is full of guys and gals who know what they are doing.

Also you are going to get better (and more) responses if you can figure out how to take some pictures; there are things that growers might recognize in your plants that you wouldnt even think to mention. Even crappy cell phone pictures are better than nothing.
 
i wouldn't worry about the lowest fan leaves withering, it happens to perfectly healthy plants. usually it's that they're shrouded from getting adequate light by the prospering upper leaves.

just wondering, what is your soil mix? even if you aren't actively over or underwatering the plant, the soil is what's responsible for retaining/draining the water so poor composition can be starving or suffocating the roots
 
Definate yes to everything.:)..I've been waiting to do this for a long time, and I realize it is a long term committment, and it is plain old work too.Anyway I've invested about 40-50 so far, I have a feeling all ive done is get a toe wet8o. I'm already at icmag, and I've been reading up. I figure I'm going to have to start over a few times , but that's o.k. I'm smart enough to understand some plant biology, I just have to put some time in%).I'll dump the dirt I have and get some plain ol potting soil, and individual nutes I geuss. Need a ph kit too peadce
 
you're just using random dirt? :S get a standard NPK mix (what you'd use for tomatoes) and mix up to 30% perlite for proper drainage. light and soil are the MOST crucial ingredients. you can half-ass everything else and still get a decent product as long as those two are done right.

if you're gonna use nutes in veg, only use a quarter dose and watch for how the plant reacts. there's a chart somewhere (google) about what signs the leaves give to tell you which nutrients are lacking or in overabundance. a good soil will contain enough nutrients to see you through the veg stage without supplementation but basic NPK mixes won't contain more exotic elements. if your strain requires those then the leaves will tell you what it wants. as for the pH kit, just get litmus paper to make sure your tap water isn't out of whack, or whatever it is you're using to water them with.

^^ I agree[mostly], I am going to scrap this effort, and start over;)....I have been looking for a simple soil recipe, but I see that is one of the biggest cans of worms I can open around here.8o Thujone says I can use a standard NPK mix w/30% perlite... is this acceptable?? Just a simple yes or no please, I'm sure their are pros and cons, but I have to start somewhere.Yes, I see this is a learning curve type of thing, I shall just keep climbing the curve=D

well....

thujone means that you should use a regular old cheapo potting mix from a nursery, adding 30% perlite to that "soil" while using standard tomato nutrients (fertilizer). You can do this, so long as the "soil" you buy does not contain time release nutrients (or bugs, mold, viruses) and the nutrients you use are instant release.

Sorry it's not "yes" or "no" lleno, but that's the simplest I can make it. I do wish you good luck.

believe me understand it's not a yes/no,black/white type of thing, many many variables...But, as I said, I need to make a decision[on soil]and start growing....=D
 
Master Nursery Gardeners Gold organic potting mix or Fox Farms anything is good. Growing all organic gives you a huge buffer as far as pH and nutrient levels. The downside is that it takes allot longer to fix a problem once it developes.
 
lleno, where are you going to shop, and how much do you want to spend? tell us what supplies you have already too... are you growing indoor or outdoor, and what kind of light(s) do you have?

word, thanks for clarifying, carl. good soil is important, but too much goodness can overwhelm your plant. LIGHT is what gets the plant to grow, so lead it to prosperity with lots of quality lighting and the leaves will tell you how much water and nutrients it needs. it's better to undershoot with nutes and increase the dose if the plant demands it rather than dump a bunch in and wind up with problems that take a lot more effort to fix.
 
Spend a lot of time on a cannabis-focused website, if you are still thinking miracle grow soil is the way to go i don't want to sound insulting but you still have to research the basics. It is a long climb uphill, 2-3 hours a day reading all about growing is what it takes.

Lesson #1: never use any Miracle Grow products ever, at all for growing pot.
 
^ reason being slow nutrient release (not to mention all around low grade soil). Hemp grows extremely fast for its size and complexity and needs a large variety of different nutrients and at different times. For instance Nitrogen (N) is vital to vegitative growth but later in the life cycle Potassium (K) and Phosphorus (P) are needed in greater quantities, while N uptake slows down a bit. Miricle Grow slow releases N over a long period (up to 4 months I think) and can become toxic to the plants later in life.

A good organic soil from your local master nursery and some all natural Alaska fertilizers (made from fish, crab, blood and bone meal, and other great sources) will do you solid. You might even want to get a bag of the dry stuff and mix it in with the soil (as per the directions) and use the liquid to feed your babies.
