Hi it would be better to help if you had a diary running. So my guess would be either during lights out the lower leaves have been lay on the soil while she slept, or when watering the lower leaves got wet and the light has burnt it. But it could also be a slight phosphorus deficiency. Its probably nothing to worry about unless it starts appearing on the newer growth. Hope this helps.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!
