This is my first time posting. I've grown 4 varieties of tomato plants from seed. I'm using a High Pressure Aeroponic system. Everything had been going well until recently. Below is a quick rundown of the grow room specs along with the issues I'm seeing. At this point I'm a bit stumped. Could this be due to overwatering?
Any help would be greatly appreciated!
