I have clones, that from the day I cut them. until right now they are 13 days old. Here are a few pictures of them. There are 10 of them. And I know that at the most, only 2 of them are female. I used a perminent marker, and it did not stick up to its name. Anyway, I would like to find out as soon as possible, if any of these clones are female, so that I can kill the males, and send the females back into vegg stage, then once they are big enough, Take like 9 clones from them, and leave them as my mothers. This is my first time working with clones. But I would think that they came from a mature plant, so they have always been mature. And My roots at set and healthy. Also, Are these not showing preflower signs already?
