You guys are the pros!
I didn't think it was heat since she's had the lights at 8" before and loved it, until the other plant grew taller. Its been at 14" now and temps are lower now with the light upgrade.
Feed..she pretty much has been feed 1.1-1.2ec for a month. Is it possible for that to change?
Ph I've had issues but it's been around 5.8-6.1
Either way..I'm not doing anything crazy..last time I over reacted a few plants died lol. Listening to everyone's wisdom and really appreciate it!
