Please take a look at the attached pics. I have lants in wk 5 of flower. Previous thrip problems but under control now. Looking under magnification, the spots are bumps. The leaves have a metallic sheen to them under mag. Humidity, light distance, & Temp are all ok. Water & Nutes PH @ 6.5 and 1300ppm. Using CO2 gen @ 1500ppm & Ozone generator is on but on the other side of the wall mixing vent gases. I can't find if it is a fungus, nute deficiency, or what. The plants look healthy and are budding great. I am concerned the issue might escalate and ruin the harvest. Any suggestions, questions?
