I described the problem, but since you asked I will do that again. You can't over control a grow. You can't bottle feed this and that, flushing and flushing and expect success. Grows don't respond well and they don't work that way. You have to find the way to grow in soil that is a set it and forget it kind of thing. FFOF soil in a large container when the plant is about 1 foot tall. Just add water and nothing else. Subcool supersoil if you want to go that way, but that's a lot of work and waiting for the bacteria to break the nutrients down to the molecular level that plants can absorb. As for this grow in question. the plants will produce very little if anything as they've been tortured by manipulating the soil too much. My suggestion is to dump them and start over as these aren't even worth it now. Or move to a state where you can just get to a store and buy, if in the US.
