hi guys i just potted up my seedling 2 days ago before i potted it, there was a small brown spot on each leaf this morning when i checked it, i noticed a slightly larger yellow spot on one of the leaves my grow tent is in my closet, and when i open the closet door, it's surprisingly warm (i don't have an exact temp reading from inside the tent), but i'm guessing it will only be as warm as outiside the tent, since when i close the closet door, that warm air will just be pulled in by the fan and over the tent? here are more details: What type of medium; soil or hydro? soil What brand and type of soil? http://forum.grasscity.com/organic-growing/1116550-easy-organic-soil-mix-beginners.html Indoors or outdoors? indoor What strain? dutch haze How old are the plants? seedling sprouted just over a week ago, ~9 days What type of lights and how many watts? LED Grow Light 300W How far from the lights? ~1-2 feet What is your watering frequency and source of water? every couple days, boiled tap water (cooled to room temp) What, how much and when was it fed? NPK? never, soil mix is water-only, although i couldn't get my hands on the tomato fertilizer for the soil mix, so i used this instead: http://www.diy.com/nav/garden/grow-your-own/fertilisers-plant-food/fruit___vegetable_foods/Miracle-Gro-Organic-Fruit-and-Vegetable-Plant-Food-9846751?skuId=10247456 which is NPK 5-6-10 What is the medium/runoff pH and PPM if in hydro?

N/A i will try to take some pics later, and post them up here maybe it's something i need to rectify by feeding it more nutes? or maybe it's just too warm?
