Hey Greek
Nice so far, and quit bumping your plants against the light. Your cola will be okay with a few burnt pistils. I will not spread.
So are you going many days without water? I read a post that said "9 days" between watering, is that right? Your pots are sitting in a drainage bowl? are you taking them out of the bowls when you set them back in the space it grows in? 9 days is a long time, you should have better drainage
Although cooler temps can dictate less watering.
Not bad, you have the six in pots, and there is one that is decidedly Sativa, the other five look like indica pheno's.
Cool grow, and I will be back to see how you are doing.
Peace
Eek
