Wilting girls in flower? Need help!

First coco grow, I'm following the coco for cannabis chart. Flora series, autoflower, 75 degree, 46 RH, they started flowering and as if they got stuck. I've noticed leaf growth, but no bud development. The bigger one, I followed the flush procedure on coco site. And she can back a little, but still droops. Any advice us welcome

Needs some calmag. Needs water. Maybe heat stress. Just have to do process of elimination and figure it out. How much nutrients and what nutrients and how often are you feeding nutrients?
