I was wondering if you leaves had burnt or what was going on. I see a lot of soil growers that will star in smaller pots and gradually move them up to bigger and bigger pots. I veg in 1 gallon pots and after they get rootbound I will move them to 7s and flip them. This is the way Doc Bud recommends doing it and I have good results doing so. I am going to try going from 1s to 3s and then into 15s when I flip at some point in the future. I should be able to get some BIG plants in 3s. I get some monsters in the 1s even. Some times they get too tall. I need to work on training better to avvoid height issues.
