second grow. good strains, just a real late start. what do you guys think?

I have several strains this year like, pineapple express, blackberries kush, og kush, blue dreams, platinum bubba kush, bubba kush, purple diesel, purple alien, purple elephants, a GDP x Larry og kush, and something called black plant. A lot of good stuff, but I just got a late start due to a contaminated source that took me about two months of waiting and finding new sources, to finally be able to get some healthy babies.
Here are pics of the ones that are flowering now, I'll put up new ones every week until after I harvest all of them.

Black plant at day one of bloom feeding-I'm using the m.o.a.b. with the ff blooming trio, open sesame, beastie bloom, and cha-ching, also, great white, jamacan bat guano, molasses and vitamin b1



Please tell me what you guys think about how they look, and how to maximize the yield, thanks for taking a look at my girls
