RQS Crits - First Grow

Brewed a Vermicast/EMO aerated compost tea, added that through netpots, Seems to be keeping water clear and no slime, plants growth seem to be enjoying it, there is new white roots as well, the older roots are a bit brown, not sure if it root rot or if its stained from the tea, they still seem quite sterdy. will see how this goes for a bit, if nt ill give the chlorine method a try. I built a peltier cooler but doesnt seem to cool the res efficiently enough, not for the amount of power. Busy with an arduino kit to sense most of the conditions. Update. 6 days later and i've decided i should probably start the flower, the plant has shot through the scrog net and having to try weave them as they get long enough. ive flushed the plant and now change the res out. the plant is growing quite nicely those Effective Micro-organisms seem to be helping since i added and keeping the water clean. and i have been adjusting the timer down to 12-12 over the last few days. and should start my flowering in a day or 2. ive added more 3000k leds this week to help spectrum change.
