One of my plants has a few leaves like this and I'm trying to figure out if it's nutrient burn or something else and when I flush them how long should I have water drain from the bottom of the pots. I did one flush last night with 6.6 ph adjusted water, 1/2gal per 3gal pots. I have my plants in a 4x4x7 tent. Sent from my SM-G950U using Grasscity Forum mobile app
