Bright spots on leaves / Critical+

[KBRA7]

Hi,

My Critical+ has bright spots on the leaves. It grows fast and shows no other problems rather those bright green patches and coarse leaves. I have more plants in the same tent - no problems at all. Same soil, same nutes, same everything...
It kinda looks like a sulphur or iron deficiency to me, but I'm not sure. She always gets some sulphur with pH down when watering. Also, she got some iron with nutes too. Could it be just genetics?

Any ideas?

P.S. 3rd photo - same plant, but few weeks earlier.

What kind of light and how high is it? They look good. I seriously doubt any micro deficiencies.

I use 4x250w HPS setup with some cfl's. The hps bulb is almost 16 inches away.
Yeah, me to... The plant grows fast. I have all sorts of strains in here - Gelato, GG4, GSC, Amnesia, a bunch of different autos... Every single one of them looks great except Critical+.

Could be strain related. I run a Bubblegum cross that absolutely hates nitrogen. Even using Lucas formula the leaves are dark dark glossy green and the tips burn while other strains in the same tent show no problems. None. I’ve given up trying to make it happy and the buds are thick and hard.
