Whats up W.C just finished reading your thread and I'm up to date. welcome to the 600 club, my grow is in my sig feel free to stop by. I'm using the same ferts/soil as you.
they look great so far, I started Growbig @ day 10. sinse AK is a sativa/indica hybrid it should be tolerant to some heat, but you don't want to rush it. day 14 would be just as good. Start with a heavy feeding on your first day, then pull back to 1 teaspoon per gallon. I love this strain its a great smoke
Your set-up is really nice I like home made operations. you did a good job. I'll be watchin this enjoy your first grow your gonna learn alot through it. +rep for the set-up!
P.S
let them veg for 30 days it will take about that long to see preflowers @ 18-6 if you go 12/12 before the pre-flowers develop you are adding stress to the plant.
