Early Miss & Jack Herer - Hidden Grow

Having seen signs of overfeeding last week, i dried out the coco and and only gave water for a few days. This seems to have fixed the issues i had with my plants. They are thriving and late this week i did my fist LST on the plants, i was unlucky and broke of a small branch that was pretty snappy (Probably due to issues earlier). But the plant did recover from this shortly after. Ive been feeding some Co2 just to test, and found that the plants like it alot. It was really noticable the day after a gave them the bottle. The Co2 is a mixture of Yeast/Sugar/Water just shaken together in a bottle with a few holes in the walls. This week is first time ive been smelling the plant. i have a pretty overkill Coal-filtration system for this small of a area so it came a little unexpected, but to mitigate smell ive been keeping my plant checks to a minimum of 2 times a day.
