Plants are coming up on 2 weeks old since they popped. I'm getting some yellow spots on 1 leaf of one of my Tangerine Dreams. Wondering what could be causing this. What type of medium; soil or hydro? Soil Grow What brand and type of soil? FoxFarm Ocean + Light Warrior Indoors or outdoors? Indoors What strain? Tangerine Dream is the one with the yellow spots. The others are another TD, Yumbolt 47 and a Purple Morraccan How old are the plants? Almost 2 weeks old What type of lights and how many watts? 400w Metal Halide w/Cool tube How far from the lights? Probably about 3" What is your watering frequency and source of water? Roughly every 3ish days but I just stick my finger in and see if they're getting really dry first. I was using distilled water. This morning I tried the water in the pic. I really need to do more research into it.... What, how much and when was it fed? NPK? No nutes yet What are the temps and humidity in the room? between 75 & 79 for temps. Humidity has been anywher from 49 to 56 What size pots? I think they're like half gallon Any bugs?
