Not a big issue but ya never know...

Week 5 in flower. Growing in soil.

Looks great overall but I’m rapidly losing lower leaves and a spotting has rapidly spread on the plant leaves. It’s difficult to photograph. It’s not brown, yellow, or other colored spots. It’s almost just a slightly lighter color of green. It’s been there a few weeks and not gotten much worse.

At first I thought it was just nutes that dried on the leaves or dried sucanat from all the sucanat water I’ve been using but it doesn’t seem to wipe off.

Can anyone tell if this is a telltale deficiency of some sort?

It’s hard to know for sure without more details on what your feeding, how frequently, pH, etc. but if I were to diagnose only by your pictures, I’d say it needs more nitrogen and a cal-mag supplement. Those white marks don’t look like bug damage but have you checked. If not bugs, I’d say the spots look like the start of a cal-mag deficiency.
