Hi all, I'm many grows in now and make it to harvest, but I have the same problem every grow mid to late flower. It starts with a few spots and moves very fast taking almost all of my fan leaves in the end. My buds make it to harvest, but I know they arent all they should be ! Any ideas what deficiency this is? Maybe I'm not feeding enough in flower? I know it looks a little like nutrient burn, but P and K deficiencies look similar? Calcium deficencies also look a lot like this, but all the diagnostic pictures I look at are similar...
Week 5 flower, Northern Lights. In a few days, this will look a lot worse, I know. Been here, done this too many times !
For now, Ive raised the lights and powered down to 80% power. The problem started on middle fan leaf edges and is progressing to the tips, a brown rust color. Lower leaves show slight brown, and a few of the sugar leaves are starting to brown as well, mainly middle fan leafs though.
