Currently on a 1/8th strength dose of flora trio every other watering. Ph going in @ 6.5. I wasnt using any cal mag until a couple days ago. But when i did the plant looked healthier overnight. Still not sure on the yellowing. Any ideas??

The purple stems (unless that's strain specific) make me think It could be a P or K issue.

They are getting 1/8th strength currently. Ill up the next one to 1/4th. Should that help?

Maybe? I've never actually had an issue like that. May be best to wait for @Waira to hop in.

For what my thoughts are worth (not much) I’d say the plant needs food.
