Any ideas what causing these spots on leaves? Bottom leaves are photo 1, and other leaves are photo 2.
Indoor
Water auto drip, 2x day
rockwool, GH 950ppm 5.7-6.1 ph
early veg, 9 days from clone
Thanks guys!
yes colder will cool a bit better.. but will also cause condensation. You need to warm up the intake air and/or reduce the humidity in the room. As long as the intake is cooler then the lights, it will cool (yes cooler is a bit better). You probably don't need much warmer... at most the room...
I use cooltubes in a vertical setup... leaves are just a couple inches from them and no burn. One was touching glass and did slightly burn, so moved it 2" away and is OK
