mold??

hey guys i recenlty have been growing auto ak47 and am into day 42 and its flowering and buds are forming, and me a first time grower(not knowing) have been spraying my buds and leaves with water and superthrive every other watering. I recently heard it wasnt good to do that and have become paranoid and have been wondering what some of these spots are..if it just salt buildup or maybe because of the superthrive.. i dunno what it is. It also seems near the buds the leaves around them have become a little fuzzy but it looks like thc forming. What are the signs of mold? In any of these pics do they look like they have mold?
Please help....thanks

i think its just dry residue from the spray that you have been spraying on them. try to spray it with clean water and see if it comes off

I don't see any problems man, you are being paranoid
