Hey, so my seedling of about 3 or 4 weeks has developed some brownish-yellow spots on two of it's leaves. Could it be that the lights are too close? I keep them around 2 inches away. It's only under two 24 watt fluorescent bulbs, but they do give off some heat. I have a fan in the cabinet to cool it down though. Over watering? I use distilled water in a spray bottle. I used soil with very low amounts of fertilizer... What type of medium; soil or hydro? Soil What brand and type of soil? Miracle Grow: 0.10-0.05-0.05 Indoors or outdoors? Indoors What strain? Jack Herer How old are the plants? About 4 weeks What type of lights and how many watts? 24 watt fluorescent sunblasters How far from the lights? About 2 inches What is your watering frequency and source of water? Once a day - distilled water What, how much and when was it fed? NPK? Never (there is a bit that came in the soil though) What is the medium/runoff pH and PPM if in hydro? N/A What are the temps and humidity in the room? Don't have a thermometer What size pots? 7x7x6 Any bugs? Look real close. Nope Here are some pictures so you guys can help diagnose the problem. Much thanks.
