I have decided to scrog the plants to be sure i wont have height issues and also this way light distribution will be optimised. I have switched to 50/50 flowering formula and will go to full flowering program next week. Lights are at 75% of their power. Evruthing going smoothly, green crack is the biggest it take up 2/3rds of the grow space, zkittlez is 2nd and critical + 3rd.
