New member here. Unfortunately I made some rookie mistakes last grow and pretty much ruined that. Now I thought I was doing everything right this go around. I’m a couple weeks in, but now I’m seeing these discoloration spots on some of the leaves. They’re kind of rust colored, brown. Only on the one plant but now I see a spot on another. I’m beyond frustrated.
Main one affected is:
GSC from Nirvana, the other spot is on my ILGM super skunk
growing in FF OF, no nutes yet.
Watering with tap water that I adjust to ph of 6.2-6.5 range, I water every couple days when soil is dry.
18/6 LED light cycle
temp currently 74 degrees F and 60% RH
