Almost to harvest; what are these orange spots on my leaves?

nutes blend looks OK, but I'd take a TDS/EC reading to get some numbers to base of of with those dosage amounts,.. i was a bit surprised with how low the ppm's were doing the same thing with MC and Bud Explosion and SC,...

I did that. my PPM's were between 550 and 700 consistently. The plant does better around 600 or so. When I upped to 850, it started to have issues.

I will add that I'm using an Octopot and they recommend 1/2 dose nutes because their system is sort of a hybrid-hydro-soil system and nothing is lost through water run-off.
