I am new to pretty new to this so please forgive me if I am mistaken. I am currently growing OG Diesel and Sage. The problem I am having is that the bottom leaves on the plant are developing white spots with even a spot that looks as if it is dying (attached two pictures of the leaf i clipped) We checked very thoroughly for spider mites but did have a small amount of mold (whitish spots that were not in the soil at the start) in the actual soil that we scooped out. I included a few pictures, the first ebing the OG 3) which I hope is not suffering a plague, The next two are of the leaf that I clipped off the bottom. The last is the Sage of a few leaves where there is a noticable white spot and burnt tip. As for the setup we are using is a 600w halide with an interchangable hps. Using coco, and floraDUO (3xA to 1-B) during grow, will switch when flowering if it survives . Any help would be much appreciated.
I have no idea why the pics are so tiny as they do not show up that way when I took the picture. Anyway here are them properly sized. The first is the OG the second is the bottom leaf that i clipped The third is the same leaf just different angle The fourth is the sage with some weird spots. They will blow up much better than the previous post.
