Ok so... when will I know to feed again?
I also heard that I should stop feeding 2 weeks prior to harvest... is this true?
Not if it's an organic nutrient. I think you said it was, so I don't think this should be done, and if you do do it unecessarily you'll possibly reduce floral production a bit.
If it's not organic, as wise says yes you need to flush. But why one would be using a synthetic non-organic in compost I do not know.
^ Well that is exactly my point. My leaves are yellow right now but we fed just 2 days ago. It takes about a week for them to turn green again so how do I know if they are fed enough? You see what I'm saying?
Also - What is the signal for stopping the feed? What should the buds look like? I want to know because not all flowering takes the same amount of time so I'd like to know what to look for to know when to stop.
Not wishing to sound pedantic, if you'll go back to my the point where I gave you the advice, you'll see I said a couple of days up to a week, not a week. Slight deficiencies = fixed in 1-2 days; serious deficiencies = up to a week.
Wise says adjust the pH to 6.5, but I disagree with that with such a grow if your tapwater is fine. I've never in all my growing career ever had to adjust pH ever, since the compost itself buffers the pH. I think this is a personally think this is a hydro principle growers have moved over to soil growing. I've also noticed a lot of growers adjusting pH having problems (whether their problems are related to this I don't know, but it's just an observation I've made). Gardeners and farmers haven't needed to do so for thousands of years and they have never had issues. Cannabis is no different from tomatoes and if you ask a hundred randomly chosen successful tomato growers whether they've ever needed to adjust pH, most would say 'what are you talking about?'.
However Wise and I both know we disagree with each other on this issue and have, lets say, an unwritten agreement to disagree on the issue and not get into long drawn argument. We get along fine anyway despite that.
You need to up the feed, and continue with that amount of feed. Then, once a week has passed, if it was initially a serious def. make the decision to increase it further because you can say then that it hasn't been increased enough.
If it's a minor deficiency, up the feed and then assess what the next step should be after a couple of days if it's not made a difference.
