I hate to tell you this but imo you need to dump them and start over. The first problem is they are not going to have any room to flower since you put them all right next to each other. You also have not sexed them so you will have males and females together which will completely ruin your crop by merely producing seeds. You won't be able to remove the males later since the roots from everything will be all mixed together.

I suggest going back and start from the beginning....and do a lot of reading first. I don't see a single method you are using as a workable one....planted together....no decent lighting....no fertilizers, no testing.

Sorry disapoint you but that's the best I can offer.
Good luck.
