Strange White Spots an one grows diffrent

Your grow is looking pretty good there. pots are deffs from whatever you sprayed it sounds like. it can be a little awkward to fill out a tent with two plants. The way I tried to do it was haveing them at opposite corners and trying to train them form one corner to the other until it was filled. but my plants started getting too big and I needed to flip to flower. was also my first grow. after that I decided to start doing 1 plant per square section. i did a single plant scrog in the 3x3 then moved to 2 4x4 scrogs in my 4x8 tent. They are going to stretch. I would think about flipping the lights to 12/12 soon. My liberty Haze from Barneys was also kind of runty and ended up vegging that one extremely long because I started a 16 week flowering sativa after the liberty to keep a continuous harvest going. and only vegged it 5 weeks,so swapped the runty liberty back into the veg tent to get huge before flowering it,and took the only 5 week old stavia from veg and threw it into my flower tent with my blackjack that was a good size to flower. i and glad didn't get rid of the liberty because I was thinking about it bc it was so small but ended up being one of my favorite plants
