the leaves right underneath my hps light is turning yellow, but the rest of the plant is still green. i googled to see what i can find, but couldnt come up with a consistent answer. they said couldve been N deficiency, heat stress, or light intensity. since the rest of my plant is still green it couldnt be N deficiency. the temp at the top of my plants are 85ish. and how can light intensity cause yellowing? wouldnt that be better for the plants.
