First grow

Fought nutrient lockout all week, one plant is clawing pretty bad and the other one had yellow around all of the edges. I suspect over watering, in combination with I didn't ph my RO water for very first feed. It was straight RO water no nutrients and it comes out at 7.0ph from tap. The one plant has come around nicely, the other one is showing signs of N toxicity. I did a light flush on it (3/14) with 3/4 gallon of water as new growth is beginning to claw as well. I put a fan on high directly on pot to speed drying process and right by the radiant heater. It's still producing new growth at a ok pace but it's definitely stunted, I believe the plant will fight through it and use some of that excess N up. Who knows maybe I'm completely wrong! Have been running a steady 79-81° day and 74° lights out. Humidity 70-72% and 65% lights out all ran by AC infinity 69 pro controller.
