Only a few fan leaves of 1 of 2 plants. 2nd time it's had bleaching in the last month but this time it's little circle dots. 2 total branches maybe 5 leaves, 7 tops with any spots at all. Lights at 75-80% considering running less than 12hours. Thoughts from you pros!?! Bg41diary
Looks like water spots. The light magnified by the water, light burned where it was wet. Is what it looks like to me. Is your grow area condensating when lights off. Mine do a little and I see stay wet leaves at times. Good luck and happy growing 🌱
I wouldn't worry, its not much and I wouldn't reduce the lighting schedule at all, it has nothing to do with it.
Probably is just water spots and your plants will be fine with or without the white spots.
