I removed the bottle of co2, and setted up the lamp (Day 22.)
The leaves are looks better (after removed co2), but the yellow leaves under and interesting spottings come forward (Day 25.)
looks like its a bit hot in the grow area since some of the leaves are turning or bend upwards with their edges, the roots cant handle all the photosynthesis happening above(as the roots gets bigger and stronger this would solve itself) if u can, turn down the temp a bit and move the light further away from the plants :) my own rule of thumb is to keep the light as far away as possible until your plant/plants tells u that they need more light, then you and the plants understand eachother and u will have a ratio:) other than that it looks good and i wish u the best of luck with the grow! :)
