Okay, first things first.. Set up 400w mars II hydro LED 2/3 Roots organic 1/3 FFOF 3 gal smart pots. 1x white widow auto 1x heavy purple auto 1x fresh candy auto Its been a long while since my last grow, this time I wanted to test myself and try to do it alone. Im working crazy hrs and adjusting to a new demanding position.. i knew id have a hard time keeping up with a forum.. mostly growing for my wife, and to save the cash she spends on it, at this point. Lol. So, i just want to get a second opinion. I have some slight tacoing, and noticed a little yellow patch on the side of a leaf. Im thinking my LED is just too close. Ive backed it off a little, but i dont want to risk any issues through trial and error. They are on day 14 from seed. New growth on one appears lightly yellowed too, but just faintly. I watered last night and added a MICRO dose of pure blend tea (1ml in a gallon). The yellow just popped up today on that leaf. Im guessing with the tacoing thats magnesium? I also read heat and humidity. The serated edges started coming up a bit 2 days ago, but its looking like its progressing. Temps are holding at 80 Humdity is 40 I do periodically open the tent and closet and let it soak in some room temp. Any help is much appreciated!
