Day 22 I topped and trimmed the lower and started LST. Not sure if this was a good idea but I have a small grow space 2.3 x 2.3 X 5.2 only time will tell. I have see some nut burn so the last watering I stop feeding the nots and gave 2ml per liter Cal Mag the Kush was not looking great and the Kush leaf color started looking better.
