Hi there! I've recently started growing my first and it's a little over a week in but I'm not sure what this brownish/yellowish discoloration is...should I be worried? I'm using Fox Farms Big Grow and Grow Bloom for the nutrients and using regular ph'd tap every other watering. I haven't seen any pictures of this so I couldn't figure it out. I'm using 200w cfl's as a hydro grow with coco and perlite. They're on an 18-6 cycle being that they're auto. Any help would be appreciated. Another note when I water them the pots aren't raised from the ground and I let it drain out that way in the smart pot. Could that cause a salt build-up on the bottom?Attachment 295915
