Ummm Chow13 - raising flora micro will add significant amounts of N.. if you’re trying to dial back N with flora trio you dial back the micro. Micro is 5-0-1 Gro is 2-1-6 Bloom is 0-5-4 I guess it’s just a sensitive auto.. it does appear to be N tox but I wouldn’t react to significantly. Personally in this scenario with hydro, I would add 10-15% or so of fresh pHd water to drop that EC a bit.. Looks very good overall otherwise tho.

Classic N tox, I get that in veg more so then flower as I don't calculate the size of the seedlings and how much it uptakes for its size. Good Luck!

Hey Growmie, No question this is Nitrogen toxicity. The dark green leaves and curled tips are a dead giveaway. Feel free to shoot me a holler if you ever need any help, I'd be honored to assist you. Hopefully, this was helpful, and remember ... "Happy Growing" and "Free your mind one puff at a time".

Yep that is a N toxicity try to follow the charts provided by general hydroponics. Lower tour flora grow to 2.1 and raise the flora micro to 2.5.
