Sorry. I have a hell of a time finding answers to my search questions. Day 29 northern lights x big bud auto fem organic grow. Finished 2nd tea yesterday, 1 week apart. Water ph 6.5 temp 24C humidity available 50 to 60 percent. One fan running. Grow light spiderfarmer SF2000, recently increased to 60 percent approx 120 watts. The smallest plant should be the same size as the rest, but she had an accident during training and lost most of her top due to my incompetence. I am assuming that I have a problem with too much of a certain nutrient and that is why it is most noticed in the smallest plant, as she would have the same size rootball as the rest of the plants and took in more of whatever is causing the issue. I don't see anything on the underside of the leaf. Any ideas? I generally water when dry. Normally every 2 to 3 days they get watered approx 1.5 L. They are in 5 gallon fabric pots.
