Couldn’t that just be new leaf material?

Anything is possible, and there are lots of ways to grow. When I see yellow between the veins like that, on older leaves, I turn my light down, and they green up.

Ok so no nutes in it. And once that is done I feed as usual? Do I need to wait or as soon as its done dripping out I feed?

Dont water again for a day or two, let it dry out a little bit, make sure the ppm drops when you test the run off to confirm the coco has been flushed of the excess and use beneficial microbes with your R.O. Water and nutrients after the coco dries a little bit, and don't over water your roots.

I had a magnesium deficiency on my last grow. I made a solution using Epsom salts (1 tbl/gal) and cal mag (1 tsp/gal) and did a foliar spray. Worked like a charm. Every 3 days and on the 4th treatment I used just water to wash off the leaves. Be sure and get both sides of the leaves.
