Hi there.. Its tough to tell.. To me It looks like overwatering a bit.. Are you letting your plants dry out between waterings// What ferts are you using? Usually if your plants get too much nitrogen they will get very green and the tips of your leaves will burn... I dont think thats whats happening here. Did you check your PH? Do you have airmovement around these young ones... If anything those plants look like there not receiving enough nitrogen, and are somewhat stagnant..More pictures would help Good luck d:rastasmoke:
