These ladies are White Widow, 1 month into flower under 600w HPS in FFOF. My feed schedule is water water feed with GH Flora Series. I PH tap water to 6.3 after letting it sit out for 48 hours.
Some leaves are yellowing and have rust-ish looking spots on them. I have used a 500x digital magnifier on them and there are no critters. I did have to re-calibrate my PH pen a week ago, it was .46 on the high side. I'm not sure if this was from the higher PH or something else. I have fed 2 times with water since re-calibrating my PH pen.
I have also rubbed the leaves with my hands and the rust-ish spots do not come off so it isn't rust fungus. Temps are ~78 and rH is 40%.
