Flip the light immediately, I'm assuming your tent is about 7ft in height and you probably got a light that is hanging close to a foot off the ceiling. Your plants are gonna double (some strains even triple) in height during the stretch. What you think looks like a manageable garden right now quickly grow out of control during the stretch.Me grow tent is 4x4 and a couple plants are 2 feet 4 inches and the other two strains are 1 foot 8 inches and the other just under that.
I’m thinking 7-10 days yet as the structures of the shorter ones aren’t super strong.
