I think its nutrients burn. Leaves are turning yellow and curling up. first thing I did was flush with water. No noots for a while.. Any other advice.. she is small and in bloom. don,t want to loose her now. Northern light auto..
This is my first grow ever and Im freaking out!
Your leaves will curl under from over fertilization. (Claw)
Yours are curling over. your leaf edges are curling up.
Possible Potassium, and Magnesium deficiency- IMO
Since you Flushed, you'll get to start from square one.
