Please help, leaf curl up and twist

AsianGuyTryToGrow · Jul 1, 2018

7 weeks into veg. One more week then I switch her to flower . This situation begins 2 weeks ago. Leaves curl up and twist more at the top. I thought it was light too close but not. I tried flushing 2 times , reduce nutrition to 1:4 but the result still the same . Any idea?
Thank you

What medium are these in?

Heat stress or maybe genetics. When it happened to mine a buddy said it is "kush curl".

Transplant it if possible. It sounds like root issues.

Thank you. But 7 gallons is the largest pot I have and they are not that big only about 60cm tall

7 gallons is a decent sized pot. I only use 4.5 gallon.(imperial) so 20L.
