I'd bring the pH up a bit, try to hit around 5.8-5.9 ... I don't subscribe to the idea of zero nitrogen in flower, the plant still needs a trace of it ... also, as your plant ages, it draws from the fan leaves, and they naturally yellow, so keep that in mind ... good luck :smokin:
the image reaper Reviewed by the image reaper on . Strange Even Yellowing I have a Master Kush plant that is about 3 months old and is on day 17 of flower. I have noticed the big fan leaves have started yellowing very evenly, and it is a dull color of yellow. Some of the big fans are now getting tiny brown spots, and it is also starting to spread to the other newer growth too. Its dark time right now, but I will have pics ASAP. But if anyone has a clue by this poor description, please let me know so I can take action right when the light comes on. Thanks in Rating: 5
