Hey boys So just started my first indoor grow box, currently in a 10L pot with about 2/3 potting mix and 1/3 perlite. Seedling is currently 5 days old and just started noticing brown edges and the very tip just pointing down, although the majority of the leaf is still a lush green. As for lighting i have a 130W true CFL, the 12+ inch long ones and had it only about 5-8cm above the seedling so just wondering if it could of just been the heat from the light doing it. There is a 120mm exhaust fan along with a 30cm intake fan running on it, and I'm pretty sure its not overwatering as I have only watered once just before placing seed in pot and then once again 5 days after sprout and used no nutes. Any feedback would be great. Maybe I'm just being over zealous with it and should just let it do it's thing. Cheers!
