dr g the benign leaf curl is due to high N coupled with lower o2 at the root zone imo, I used to grow in subcools supersoil receipe (until I made my own which I prefer) and the leaves curl when they hit the supersoil which is high in N and worm castings which are soggy.....I corrected it by raising oxygen levels in the soil in the hope of increasing metabolism which seemed to help, but u can increase o2 and decrease N with ur system nee bother..?
