Omg Mile high guy. It's a good question. After all it's all fun. plus you can go buy whatever the fuck you want anyway. Do your pots have some kind of drainage holes? If not, just get under em somehow and drill holes. That's one. 2, you have no perlite in there. Go get some. This will require you to repot and if you have some soil left mix in something like 30% perlite. As long as you're doing that, get some better pots. YOu are doing something right, and I think it's that your light is ok, I mean not by all this forum peoples standards but it's ok, and your height distance seems to be workng okay. That first pic just above looks fine. The others not so much, but your nodal spaces arent that far apart. That one with all the purple edges and spots looks pretty bad, but try to save it, just for the hell of it. Anything can be saved but it is going to take a long time. Dont try too many things. Maybe just plain water and don't over water and don't under water. Just work on that. They need to recover for some time before you try flower. If you must try fertilizer if it's not in the soil already, just try a little Fish Fertilizer from the depot, in my opinion. I wouldn't pay for clones especially not now. Your just going to fuck them up. Well unless you can grow them outside there.
