You do have some interveinal chlorosis but likely too late for leaves to recover. Not knowing anything else about your grow makes it hard to diagnose issues.

interveinal chlorosis
Interveinal chlorosis, often called iron chlorosis can be caused by a deficiency of several micro-nutrients; Iron, Zinc, and Manganese , all of which the symptoms look similar. Yellowing of the leaves can be caused by a number of cultural or environmental issues. Normally it’s due to the pH of the soil being too high.
Water Saturday, so do I need to wait tell little on dry side run enough water through to get good run off then come back and feed some cal mag,

Looks like nutrient lock out due to overwatering. Probably a touch of root rot. Let her dry out a little…
I’d say since you flushed the pot and didn’t refeed them after your plants are cannibalizing themselves to build buds
Slurry test that ish!!!

You could have calmag and phosphorus/potassium deficiencies. Have you checked your run off numbers? I see a calmag deficiency, but leaf symptoms from nutrient deficiency or overload can often resemble each other, other than nitrogen and that one is typically easy to spot. Moving into the flowering stage cannabis plants require less nitrogen and more PK, it can be difficult to read leaf symptoms, so I rely on the run off numbers

I’m always lurking somewhere but I was waiting for all the “does this look like it’s time to harvest” questions to go away
