Discoloration on my leaves a month into flower

I grow in roots organic green fields soil and feed roots organic terp tea on their schedule. Watering with RO water with cal mag added back, pH to 6-6.5.

Noticed this yesterday but it looks a bit worse today. Yesterday was feed day, so I top dressed and watered.

Have you tried extra cal-mag?

I have not. I've been doing ~3-6ml/gallon. I'll up it in the reservoir now and see if that helps when I water next.

I don't see a problem if it's only a few here and there. It's does not seem like your crop is struggling at all. Id see concerns if it was rapid all over and over a short period of time. Def keep close watch ofcoarse

Yeah, overall crop seems much happier than it did last cycle when that tent was _much_ more dry and warm. I'm going to add a bit more cal-mag to my water next time, but I won't make any more changes unless things keep getting worse.
