3 days after I gave the auto-flowers their first nutes my best looking plants leaves are all curling downwards around all the leaf edges, making them look super thin. Can be seen in the 2nd pic of Blueberry Kush #2 above
Looks like too much water, maybe excess nutes,possibly the beginning of root rot, get some mycorrhiza in the soil to help combat it.. rootshield or piranah from advanced nutes. Let it dry out a bit before you water again.. hope this helps..
I think with jock horror you may have a root problem, try repotting in fresh soil with plenty of drainage ie. Perlite or something. Your blueberry kush 2 is looking like a nutrient lockout or an overfeeding. Could try a flush out and lower nutrient levels for her. 😁🌱The rest are looking nice though! 👍
