OK. A. you water too often, you never water them every day. That gives you a shallow root system. You also shouldn't be feeding them every day. Your temps are on the high side, and I'm thinking you are getting some heat problems. I would have said root lock in those small containers, but it sounds more like you just don't have root support. There's a whole bunch of stuff that could be wrong. Vent them a little better so the temps go below 85 during the day, water at most every 3 days, I'd suggest transplanting but I have a feeling your leaves feel dry yes? So stick to whatcha got. Autos flower fast so you may be able to squeeze by. Good luck.
