I had a similar situation, but I don't know if it's the same thing. I was giving them plenty of food but they were showing a N deficiency. It ended up being that my pH was too low and I was locking out the N. I was in the low fives due to an uncalibrated pH meter. In flower you can run your pH higher like closer to 6.0 - 6.2Thank you. I think I had seen a similar chart somewhere else. My situation was very odd. Had signs of N deficiency and N tox. Very weird
