I’m growing in FFOF. I just flipped to flower and notice my fan leaves looking a little discolored. Anyone knows what might be going on here?
I feed nutes once a week, I supplement with CalMag and MagSulfur. Temp runs about 77-80F during the day with RH ranging from 56-60%.Lights off temps Are 67-70F and RH ranges about 60-65%. The color on the leaves looks black.

Haven’t checked my runoff in a few weeks, so I’ll do that. I pH my nutrients and water all the time. I’m going to give them pH’d RO water for a couple of waterings and see what happens.

Yeah because that’s what it looks like I don’t think wind would be so sever maybe a light yellowing and a papers feel

Run off out of soil means diddly shit. Won't tell you anything at all.

What goes in is what matters.

And yes it can easily be wind burn as the signs point straight to that.
