over the last week I have had a leaf issue cropping up. this is my first run with coco and im halfway through week 6 flower. I popped open the tent and noticed leaves were tacoing, they are rough to the touch and some got a lil brittle. there is a mottling to the leaf. having a little trouble pinnng down the problem. heres the specs and a pic.
when I was running DWC I was always chasing a magnesium deficiency, maybe the same thing?

the pic is the same leaf, just one with flash and one without.
