Basically Leaf Roll is a physiological problem while most causes of leaf curl are environmental.
I think I went over the leaf curl stuff in that same post but here it is again.
Leaves curl when it's too hot, too cool, too dry, too wet, too windy, or when the
plant has a heavy fruit burden and most hybrids have leaves that curl normally.
If leaves curl over into a tube like structure, check for aphids.
So as I said above, I ignore leaf curl unless there are other symtoms.
Leaf curl can occur at any time while physiological Leaf Roll usually occurs early in the season when the plants are still immature, as I said previously.
The leaves arent brown. . nothing looks dead, but it was RIGHT after doing this. Think i may have shocked the
