That looks like nutrient splash or foliar feeding burn to me. My plants do that exact same thing whenever I splash res solution with nutrients on them or if I foliar feed to heavily and allow the water to build up turn to droplets and puddle and sit for to long. I could be wrong though.

Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy diskSudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.3 years ago

Dry spots on sugar leaves, plant late in flowering, also spotted on another one in the same reservoirHi guys,
my plant is around 2-3 week before harvest.
What is the cause of the these dry spots on some of the smallest sugar leaves on my plant?
The ppm might be too much and is around 1200-1300ppm.
PH is 6.0-6.1
I've spotted it on one other plant in the same reservoir.
Thank you3 years ago

Nutrient deficiency? Or just getting ready for harvest? Sister plant is very green (different strain, strawBerry cheesecake, last pic)Plant is Raspberry Kush, I’m assuming it’s because she is close to harvest and it’s sucking all the nutrients out. Also, looking up other raspberry kush diaries i’ve noticed they tend to end up pretty yellow. Was fed bloom nutes yesterday but noticed lots of yellowing today.Week 9
