Critical Masss AutoFlower

Beginning transition from germinating nutrients to veg nutrients. Looks like i gotta ease up on the watering. It's cold where i am so my heat is turned up and i was worried about it drying out my plants. My new humidifier crapped out and am waiting on a replacement so back to my 4 hour refill one for the time being. Concerned it might also be getting nutrient burn so i might start diluting the water a bit to see if it helps.
