Using a 400w MH bulb 12 inches away from my plants in a tent with a 190 CFM fan exhausting air every 15 minutes and an intake fan at the bottom circulating air as well (I'm in the beginning stage of veg so don't run the exhaust 24/7 as my room is already properly ventilated). Few days ago, I noticed some brownish spots on my bottom leaves but the new leaves looked normal... than the leaves were really droopy even though I hadn't watered them and now the new leaves are starting to develop brownish spots as well. I can't figure out if this is light burn, heat stress or a nutrient burn somehow (people say Fox Farm Ocean is too hard for seedlings).
Humidity in the tent is maintained around 35-55% (mostly around 35%) with temperatures ranging from 66 in the night up to as high as 88 during the day time. Oh and the plants are in 3 gallon smart pots being watered with tap water (no chloromine). Really hoping to figure out what's wrong with this plant and save it before it's gone. Thanks guys!
