I'm using an AeroGarden 6 for my current grow. I had a few questions, this is my first grow by the way. First, i had fed my plants Xnutrients (1/2 the normal dose) and one of them got what looks like very bad nute burn. so Now I flushed it with normal water and will for 1-2 weeks depending how plants look. So when i fed my plants I had normal water in there and just mixed nutes a bit after putting in, and didn't change the water until the next week when i had to feed again. My question is am i supposed to empty and refill the tank BEFORE the next week? or is it fine leaving it like that? Also, for Autoflowering plants, if i switch from 24 hr cycle to 12/12 will they begin to flower? or not until the plant itself is ready? and I had a fan running but it seemed to be too strong and was moving the stems of the plants so i took it down, does it actually need a fan?
