I'm not quite sure what it means for it to be leaching nitrogen from itself, but I just put some miracle grow fertilized soil around it today, so I hope that helps it. Before that I didn't fertilize the soil, but it seemed to be good dirt since there's a lot of other plants growing in my backyard. Also, those pictures are kinda messed up color-wise, cuz I played around with the white-balance on my camera phone, most of the leaves, except the lowest ones, are a much darker green than that.
I haven't been covering it at night, it gets pretty much pitch black in my backyard at night, so I didn't think I needed it...do I?
I actually planted a good 10-15 seeds around my backyard, but it was from a sac I bought that had a bunch of seeds in it, and only one ended up growing into a plant. Honestly, I just want the one, but I wanna make sure it buds and at least gives me something to smoke in the end.
