I feed until the last feeding when I do 1/2 strength. I understand the theory for "cleansing." I just don't agree with it. Maybe it applies to hydro/synthetic nutrients. I use more organic sources of nutrients.
What were the breeder's recommendations? I think we're talking about autoflowers. Typically 11 weeks. When I grow autos, I get into 12 weeks. Even a week more. You want to go by the pistils and trichomes. I think I mentioned this in your
other thread.
I think you'll make more impact with more light. I agree with you about putting your light on the side. I don't know if buying a 2nd one is better than using household LED lightbulbs. I know the latter have a good spectrum, grows very well. I would be inclined not to put all my eggs in one basket (unknown spectrum of your light).
