Oh Bro, considering the good general health of the leaves, these spots are very suggestive of droplet sunburn.

Would Epsom salt be helpful for these brown spots? If so, how many ppm? Is it OK to reduce pH with citric acid and distilled water in nute mix?

Leaves turning yellow with brown patches
I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?
