Bit of help plz guy. I have noticed some discoloration on my leaves, do they need re-potting? they are just under a 20w flo bulb for now in low nute pre mixed potting soil, not watered for a few days as the soil is still vary damp. roots coming out of bottom of cup drainage holes already ( day 7 after planting seeds directly in soil) 4 critical kush, 3 northern lights blue and a herbijuana jack for those interested
