Leaves changing color somewhat quickly

[Coopaloop]

Anyone know if this is something I should be concerned about? This is only happening to a few leaves but it happened within a few days. Some sort of deficiency or toxicity? Indoor under a mars hydro ts1000. FF Ocean forest soil. 5 gallon pot. Week 5 flower. Only one of 3 plants doing this. Thanks in advance.

How much are you watering?

I'll take a stab. It almost looks like a little nute burn and an iron deficiency both are symptoms of over feeding. Also could be the pH of your media. Have you tried testing the run off ppm and pH?

Magnesium deficiency. Dark green indicates high nitrogen.

Agreed. The N shine is there too.
