I keep getting this same issue with yellow between the veins. I'm growing in ocean forest with feeds of Fish Hydrolystate and compost tea. I been feeding cal/mag every watering and my light is a COB.

They look fine to me. That’s typical of a sulphur deficiency. Yellowing leaves at the top/middle of plant.
Is it progressing upwards? Or starting in the middle?
If it’s progressing upwards could be nitrogen def.

Progressing upwards, sulfur defiency makes a lot of sense. I been feeding with fish fert and high p bat guano and cal mag. I'm guessing the high cal locked out the sulfur.
So weird this always happens when I go into flower.

Sulphur doesn’t get locked out I believe. It’s just lacking in your plants diet. Epsom salts are a good source of sulphur if your plants can handle the extra magnesium
