Freebie Afghan Autoflower

Found it hard to raise the humidity in the tent but seedling was to be doing fine with occasional misting. Using filtered tap water and pH adjusting with citric acid. I gave her a light feeding at the end of the week because she’s in a sterile seedling mix but I overwatered the entire nursery in the process. Trying to figure out how much water she needs in this size pot with this medium. I’ve always been terrible with indoor seedlings
