I’ve never seen this before. I’m thinking nutrient burn, because she got a dose of neptune’s harvest 3 days ago.
Droopy leaf posture and the brown splotches look like too many nutes. Maybe PH is off?
This current posture and color happen before the dose of Neptune’s Harvest 3 days ago?
After neptune’s, I’ll check my ph today though.
I’ve had a thought… she has started to flower in last week. Maybe I need to change to my flowering nutes? Deficient in something?
Correct soil pH. Most problems resolve themselves if it’s corected. And yes you should switch to flowering nutes (only after making sure the pH is ok). Best of luck!
