Help! Pruning while flowering - bad idea?

My babies are about 4 weeks into flower and I found what looks like a black fungus or mold growing on a couple of the smaller buds on both plants. I'll try to post a pic tomorrow. Both are from bagseed (one sativa and one indicia). I pruned the whole branch off the sativa but have yet to touch the indicia as it is the more promising of the two. My question is this; will pruning cause the plant to stress and go back to veg? Also, if this is mold is the whole plant(s) hosed?

Thanks in advance for any adivce you may share

i would try and harvest what you can.. mold usually means that the buds trashed... but best of luck eitiher way.
