I haven't done autos yet but the one thing I've learned is patience! Just give them time to do what they're naturally designed to do lol, I panic so much over every change in colour and every droopy leaf and I hit google and spend hours figuring it out and the next day it's something else completely I'm winding myself up about. I'm trying to just Zen the rest of my grow or I'm gonna give myself a heart attack or something and the plants know what they're doing so I'm just nurturing them through it
*EDIT* Sorry, I did have a point, I'm stoned and I forgot for a sec, my girls hated the big light to start with, we did lose a few days growth over the stress of going under the 600w hps, so some plants are definitely more sensitive to the strong lights.
