These plants have been flowering for three weeks and have yellow spots, some of which have turned brown. I am using general hydroponics Flora Nova bloom nutrients. The N-P-K is 4-8-7. This is my first grow and I don't know what is going wrong, please help!
I'm a dirtbagger so I really should not be saying anything here. But, IF, I had to bet, I'm going with Nitrogen deficiency. What is the EC/ppm of the food?
