You can safely up the vegging nutrients to about 650ppm. My issue with autos is exactly what you're experiencing, you can't afford any mistakes, the clock doesn't stop because mistakes were made. Soil may be something to look at as hydro can be a little tricky in the beginning. If she was stunted badly during veg, you're not going to get great results. Recently burned my fingers with some auto cheese, only 1 out of the 3 seems to be a success.

Thanx for the reply I'm well aware of what you say about the autos it's my first grow so I'm expecting some mistakes from my side just not sure what the problem is would you say under feeding ?
