Dying blotchy leaves in flower

[Alpaca]

I'm not sure what the problem is here

Its mainly appearing on leaves that receive the most light. I'm using 600w worth of quantum boards at about 50cm distance from the canopy. Am I too close of is some deficiency showing?

My bad I should have thought of those. Recently flushed so these factors should be pretty easy. Grown in lightmix soil, feed them about 10mls of terra bloom per watering (5-7 liters) and 5 MLS of calmag.
Ph should be hovering around 6-6.5
