Leaves dying
Cannabisflakes
started grow question 6y ago
I removed these dying leaves, they were burned, with signs of necrosis and curling down. Now the plant siting next to the "sick" one started to show some early signs, similar to what her sister showed weeks ago 😪 Does anybody know what is going on?

Calmag problems usually caused by too much phosphorus. Bloom booster is a likely culprit.

What are this yellow spots? They are getting worse each day, and if they are on the edges the leaves start to break.

Leaf issue
Got an issue with some leaves turning this colour. Anyone got any input? We are nearly 7 weeks in, growing in compost and only feeding 1ml/ltr. I’ve also attached a picture of the whole plant. Leafs at the bottom seem to be turning, the ones up top all seem a good colour.

Calcium Deficiency Won’t Go Away DWC
So plant #1 is still having some Calcium deficiency issues. I’m using RO water and giving the recommended dose of CaliMagic which is 1tsp(5ml)/gal. I’m in DWC and using LED full spectrum lighting. Why can’t I stop these spots? Should I give more than recommended dose of CaliMagic

Does the leaf in the close-up picture look like the beginning stages of a spider mite infestation to you?

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...
I was looking after them just yesterday evening and the plant was fine, however I did a mistake. The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on. Right plant is completely fine. No pests (thrips spimis etc.)

Sugar leaves burnt/dry spots.
Weeek 10 of Girl Scout Cookies Auto is showing some deficiency/excess or lockout but just on the upper sugar leaves of the older buds. Rest of the leaves on the plant look good.

Calcium Deficiency? pH problem?
Brown spots on some newer growth now on both plants. Canna Terra Flores brings the pH of water down too much even at a half dose. I didn’t think I’d need to adjust pH much in soil. Any suggestions at this point? Thinking to just feed plain water to bring the pH up at the roots

See the last photo from Day 24. There are a few spots on this one section of one leaf. Because it's limited to this one area, I'm not too concerned.
