Looks like you have nitrogen toxcicity. Dark shiny leaves and “clawing” are signs of excess nitrogen. Molasses has a decent amount of nitrogen in it and isn’t meant to be used more than 1 or 2 times per grow. Not sure what else is in your mix but I would cut that out and consider a partial flush.

Be sure it’s dark green and shiny though. Purple pigmentation is normal in some cultivars from exposure to intense light. Either way, new research suggests that the production of anthocyanin(purple pigment) directly competes with canabanoids for resources. Not exactly a good thing.
