Just popped a seed in the ground yesterday. Pretty pleased with my setup so far. I have a 2x4x6 tent. only growing 1 plant, just wanted extra room to be able to move around. I have a 6in t6 cloudline fan by ac infinity. I love it so far also the carbon filter should be here in a week. my soil is a mix of happy frog ocean forrest and coco. my light is a crappy sunraiseled 1000w. it isnt super crappy but it's what I have for now
I saw a message of yours in another diary,about smell. burning incense would help,in another room of course. or there is something called ONA Gel if you were interested in.
Looks a little over watered! Look up over watering symptoms you'll see! That could explain a few of the issues you mentioned!
What's your pot size?
Are you using a EC/PPM/TDS meter?
