Leaves, rust dots, yellowing margins
marihoochistarted grow question 2 years ago
These leaves look like torture, are they getting too much or not enough? Brown rust dots, yellowing margins that turn brown; petioles are purple.

Looks like issues in the root zone. Test your runoff. I would bet the ph is in the 4.5-5 range. This will affect the uptake of nutrients the plants need in flower.

Did those leaves come off the top or bottom of the plant?

Looks like a calcium deficiency. Coco always needs extra cal mag. The other option is your ph in your coco is getting out of range. In heavy flowering in coco for myself my ph will rise causing lock out if I don't heavily dose it with extra potassium and phosphorus to maintain and stabilize it. Lack of enough nutrients is what does it to me. I would run a ph 5.8 water through till run off. Get a test reading of ph. If it is 6.3 or up there is the problem. Ph is very important in coco grows, but results are strong.
Feel free to dm me if you need more assistance. Happy growing 🌱

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.

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 you

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.

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate
