Leaves dying
Cannabisflakesstarted 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.

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10This is my second attempt at cocus
I work with Plagron nutrient solutions(Coco Nutrient)
I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!Leaves. Edges burnt

On lower leafs some brown patches started to appear and leafs are turning to a yellow color. Think is either Cal def by how it looks like or it is because of PH fluctuations as last week we changed our PH to 6.2 for 4-5 days and now it is back to 5.9 and under 24h spots appeared?Week 3

Leaf issueGot 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.Leaves. Color - Mottling

Purple Queen show some spots on the leaves, what do you think it is?The middle plant show some spots on the leaves, what do you think it is? 😜 Note: I lower the PH in my autopot system to 6.1. Normaly my bat mix have enough nutrients for the first 6 weeks. The dark color is because of the higher PH > to much Nitrogen intake I think.Week 6
