2 weeks from harvest, yellow leafs

Is this ok? 2 weeks from harvest, got a few nanners aswell but the leafs are yellowing, running lucas formula in dwc.

Well it's going to have to be ok 2 weeks from harvest; you'll never green them up now. It's not too bad but it'd be better if they were just starting to yellow at harvest. Nanners are always bad, nip them off with your thumbnail and get them out of your grow before the pollen gets to your pistils.
