Are you deficient in calcium?

I TRYING WITH PICTURE THE BEST I CAN . IT COULD BE APHIDS . PLANT WILT LEAVES COATED WITH CLEAR ,STICY VARNISH LIKE SUBSTANCE on which gray- black mold grows. Look up aphids and look under leafs real well . If find them use Neem or insecticidal soap or even dish soap real lite.What sucks in flower. This is not a good time. Or it could also be Scale Redfish brown mottled brown,tan or white to reddish pink bumps appear on leaf axils(where leafs attached to stems) and undersides. The solution is much the same Neem and the like . I'm sorry my friend it sucks this happened in flower. If it's just on leafs cut them off and Neem or soap water lightly on rest of plant. Try your best to keep of nugs. Remember Neem says you can use in flower,BUT who wants a garlic bud. Some do lol,but u know what I mean. Make a good grow diarie and it helps my fellow grower. You just gained some knowledge by this mistake and now u could avoid it next round as you get better and better. Blessings on all u grow.
