Stepped up the nutrients to about 350 ppm at 5.7 ph. Raised the temps and RH a little higher to about 79F and 50%. I had my new air pump in this bucket but I think it was too strong and I swapped it out for the weaker one. It was 35w 950gph pump, I'll use it for the bulk of the grow once the plants get larger. But with such a small container the hot air from the pump was raising water temps too much and it was bubbling like crazy. Back to the 6 watt pump for now. I accidentally damaged the roots on the 4th plant :( I transferred it to soil just for fun hopefully it recovers but it will be stunted. The rockwool cubes were starting to get wet on top so i covered them with cardboard to prevent mold from growing.
