Ya, I was wondering if its nutrients but usually too much nitrogen shows signs of yellow/white/browning at the TIPS of the leaves.. Thats what i've been taught anyway, and noticed, too.
Littlegrower, thanks man. I actually topped/fimmed most of them a couple days ago. The shorter ones are NOT topped yet as I didnt think they had as much root-mass, but they will be topped/fimmed in a couple days.
LST SOON!
