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.

Deficiency or Pigment?I have strange brown spots appearing all over my top fan leaves at week 7 of Flower. I thought this could be genetic coloring starting to fill in, but now I think it's something more. https://media.growdiaries.com/static/post/photo/31218/4085521_grow-journal-by-livewire99.jpg

Brown/rust spots have been increasing on one of my 3 plants. Appearing on upper and lower, newer and older leaves. Does not appear to be a light/heat issue. Treating it as possible Cal def by increasing cal-mag nutes.

Their appears to be little brow spots/specs scattered on the fan leaves, I feel like I’ve seen it before but completely forgot what it was so if anyone knows if it’s a deficiency of any kind it would be appreciated. I ruled out nute burn because only one out of four has it.

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

should I be worried about those little white spots, do they indicate on some kind of deficiency or they will go away eventually by themselves? I mean there aren't much but still, got me little worried.
