What brand is the nutes? If its not organic You should only feed maybe 1/2 strengh or less so you don't burn them.They should have veg nutes for at least four to five weeks or until vertical growth slows.Then go to flower nutes still at 1/2 strength.Don't start feeding them until seedlings are at least a couple weeks old.Make sure you check your ph after you add nutes to your intake water, and then check your runoff water.B othe should be about 6.3 or 6.4.

Pro Mix has enough starter nutes for about 2 weeks, then a very light feeding is usually needed. Those are not the best nutes for growing autos. You should have something with lower P and K for veg and something with some N for flowering but more P and K. Autos can be a bit nute sensitive so if you use the 16-16-16 I would start out at about 1/8 strength and slowly increase it. I doubt you'll be able to go over 1/2 strength at anytime during the grow without seeing signs of over feeding. As Namvet said, veg nutes till vertical growth stops, then switch to flowering. https://www.autoflower.org/f44/life-cycle-auto-flowering-cannabis-5113.html
