In week 2 from germ, on 1 of the plants the seed was stuck on the leaf, I carefully tried to remove it and ended up damaging the plant. The damaged plant is the smallest of the 3. I will call him Steve. Aerated 1 gal of water, brought solution to 850ppm and then ph balanced to 6.5. I added 2 shot glasses of the mixture to all 3 containers. Continuing 24 hours of light.
Noticed RH dropping below 40%, added a cereal bowl with around an inch of water and a towel in the grow tent in front of a fan. Raised RH by 6%, added a second bowl, stable at 51% rh, buying a humidifier
Side note. RH was dropping below 40% when fan was on setting 2, assumption that the fan isn't sucking in enough air from outside the tent. Increased fan speed to setting 4, dropped temp from 75 to 74 and brought RH up to 55% after about an hour.
