As great a tool a these forums are, sometimes it's like a hypochondriac discovering WebMD. I know I was EXACTLY like that. Your plants, like every other living thing, are gonna have good days and bad days. They WILL develop "hang-nails" and exhibit little signs of distress for no apparent reason. And if they ARE getting sick for real, you have days to correct the problem (in an organic environment) Christ, i remember stressing out when a leaflet hung just a tad bit lower than I thought it should!!! Relax man. Don't stress over this. Let the plant do it's thing, just be there for it and give it what it wants. (Not what you think it needs! ​And certainly not every new "snake-oil" that hits the market promising bigger yields and more THC!!!)
