Could be a bit of moisture build up and your lights just roasted that spot slightly. I wouldn't worry unless it starts to spread or you can see it from underneath. Happy Growing!

Curious if anyone else has experienced leaves like this on Durban’s. I know I’ve seen leaves like this when temps get cool outdoors but all flower sugar leaves are turning. Watered regularity and fed well in my opinion, so I’m not sure what else it could be. Thanks in advance!

Brown Spot Assistance, Please Noticing these brown spots on the leaves are getting worse. We started Fox Farm Tiger Bloom about two weeks ago and my thought would have been that would have helped. Would appreciate any insight into possible cause and level of concern. It’s flowering really well. Thanks!
