Ok i topped off all of the plants, and while i did that(that day) the leaves got to like a lighter shade of green, and the tips of some of the older leaves burnt off. i think it is like a yellowish grey at the tips. That happened maybe 48 hours ago. I stopped giving it nutrients, only water now, i stopped spraying the leaves(?), and raised the light from like 20 inches to about 3 feet. Things are already looking better, and i am getting mad sprouts around where i topped the plant. I tried not to worry too much about it, and not let it get to me, and it all worked out fine. gasp of releif.
