Hello everyone! This is my second closet grow, and after a successful first grow I am stoked to harvest again. I have 6 plants in Fox Farm soil, under a 400w hps, light at 12/12, circulation fan, temp stays between 72-76 degrees, humidity stays around 40%, watered with Nestle Pure H20 (which is supposed to be a pH of 5.5), and they are fed Tiger Bloom, and Big Bloom Fox Farm nutes every other watering (once/wk).

All of the plants are big, green and healthy except for one, Wild Purple, which is turning a light green/yellow color and has developed brown spots on the fan leafs, and some of the top leaves. The buds that are forming are beautiful, and the plant doesn't appear to be croaking.. but I simply don't know what the brown spots are, and don't want to let it get any worse. I've checked for spider mites/pests/bugs- none. I do feed a lighter dose of nutes, because I tend to err on the side of caution. I checked the soil pH today and it was 7.0, which I know is slightly high.

Any advice would be appreciated. I'm leaning on feeding it some Cal-Mag to see if it's a Mg deficiency, but it is such a beautiful plant, I really don't want to use it as my test subject. Thanks in advance, and sorry about the crappy pics!!!!

Happy Growing :jointsmile:
