The fall grow for you should be so nice compared to this one. You will see. But hthe third grow, you will have so much experience, and a cabinet full of weed so you never have to look back. Environment is the key for grows. My room is set and the temps and RH combo are balanced. Use the nutes as directed for the most part, know that Cal Mag is your friend if you use LEDs, and you will grow some beautiful stuff a short long as you start with decent genetics.
It's not far away man. Just a couple more months and all will be good. I have to practically give this stuff away to friends just to clear space in the cabinet for the next grow.
