[d420]

Having a lil trouble, I am on my fourth grow, and have been vegging for about a month and a half, and have been getting bad looking leaves , I started giving them cal-mag and grow big, it doesn't seem to wanna clear up. I checked the ph and it is a little above 7 in soil. any suggestions? Thanks for your help. d420
