RedWeaselParticipantNovember 16, 2025 at 7:44 amSome already know, but this is my first photoperiod. She’s Sensi Northern Lights at Week 8 and just got flipped to flower yesterday.
She’s showing a small bit of canoeing. Not a ton, but since I can make small adjustments with my controller, why not make her comfortable.
I did introduce FR & IR at flip while also dropping my DLI down to 25-27 to reduce flip stress.
Should I have also dropped my VPD slightly, like 0.1 min & max ranges?
I could have it coincide with my planned DLI ramp over the 3 week flower stretch.
I’m not overly concerned at all, just figured if I could make a small adjustment to make her happier, why not?

I may have figured it out, but would still invite input. My leaf offset somehow got reset to 0°F when I switched automations. I took a reading and set it back to -2°F.
@Newleaf put out a post that reminded me to check, so thanks man!

Thats a good chance. I dont know how all these controllers to give good input. I have classic ways still because i dont trust situations like this. Automated becomes less caring and things are missed. Good catch on your part, girls wont get away with anything lol. I thought of the red, im seeing a lot of foxtail and burn and damage since people have been getting into this spectrum stuff.
