OK, so, this is the fourth grow in the box, the first two were using the Cloudponics control box but then they closed and no more support so I have rigged up systems to check and balance. I keep the room between 70 and 80 degrees, we just had a cold snap so I use a small propane heater for the room with a thermostat. Inside the box when the lights on currently running 18/6 it averages 80 degrees. My prior grows, by now the roots were growing into the water box but these are just now, appear to be coming through. Maybe they cant and thats an issue(?). The 4 plants are drinking about 1 gallon a day. I have always used distilled, same brand since started, just felt was more pure. At this reply, the water tank was up at 87 degrees. I had unplugged it but with the 28 degree days we had recently, I plugged back in. I have a humidifier in room. I am also growing started tomatoes and stuff on shelf under light for the garden and they are doing well at 18 days.I use flor product sand the only not pictured is the "green" grow formula. The PH fluctuates from 5.6 up to 6.8 and I usually don't have to do too much, sometimes raise it and that can be just adding straight water no food. I have been feeding by the chart included. In this photo, I see my conductivity is not reading. This time I sent all plants and as you see the one I showed is the early sign one and the ones in front are feminized blue ice. I truly appreciate the replies so far. Please advise if you require additional information.
