So these showed up today on plant. I realized a couple of days ago that this plant was too close to heater. Stressed out leaves and such. Had a possible nitrogen issue a few days ago and discussed here. Is this heat related or am I looking for something else here. Checked for pest and vermin very closely and could not located anything with microscope. Is this a continuation of nutrient issues or the heat taking its toll? Carnal Knowledge, in ffof soil, 3 gal pots, bestva 1000 led, 4x4x80 tent indoor, avg temps high 70's day low 70's night, RH avg 50% temporary 60% after watering but not a constant, day 67 from sprout week 2 flower, last fed 3 days ago 688ppm@6.57, runoff for this plant was 708@6.36, the other two were 790@6.36 and 634@6.47ph.
thanks for any help

It looks pretty centralized to that one leaf or so. With that being said, I would just keep an eye on it and make sure it doesn't start to spread otherwise, I would just let it ride.
I agree with @gregthe357 ... Small markings like that on one leaf are usually nothing to be worried about.
