Supercrop, as in bend/break the stalks. I would say yeah, you can still supercrop. I have at about that stage and even a little later. Mine have responded great and the stalks are now thicker and they are standing up again but there is an obvious bend in the stalk, and it's created a knot of sorts which is great for nutrient delivery. The canopy has evened out, and seems to be working well. Good Luck!
