Autos don't like a lot of nutes early on which is why, when I grow in soil, I use ProMixHP since it has absolutely nothing in it. I'll start my nutes slowly at week 2 and including bloom nutes because autos may go into pre-flower in week 3... and it doesn't hurt them to get those nutes early...
Anyway, you've fed them the right amount at the right time and things should be good! Good luck!
