Hello guys, My plants are on week 5 of flowering and i sew some yellow leafs and those yellow leafs turn purple leafs !!! I feed 200 ppm N and 1200 ppm PK. Please i need ur help guys !
Yeah I had same problem happen to me. I was LATE to fix it which didn’t seem to effect much other than some ugly looking leaves as they aged. I would flush and next watering give a good half dose of nutes and increase back up from there
It looks like it's generally underfed. Next time add more N during the veg and early flowering stage. The purple could be completely normal. Some strains will do the complete fall color change.
Can you tell by the pic what I have going on, it’s not every leave only say .5 percent, people are saying cal mag, some say flush some say more nutritious, I’m lost week 7 of ten flower
