First time experiencing

Hello all,

Please may I ask for some advice I feel like this is septoria but not entirely sure as it's the first time I'm experiencing it, attached are some pics to view. I found a red mite issue starting so sprayed her off with water then gave her a pyrol treatment (can't play with red mites) 18hrs later I have found what seems to be mottled spots very close to her buds.

Not septoria

Do you spray your plants with anything or could anything have got on them?

Concerning that it's only on the calyx's.

I did a biogrow pyrol foliage spray to treat the spider/red mites that's all. Washed her down the next morning with distilled water and she went back into the greenhouse with her sisters 8 hrs later when I went to check the temperature and ph I found her like this.

It seems to be spreading still so a bit concerned she is contagious and will infect my others.

These are pics 1st is of the original Moby I posted last night, 2nd is of a Blueberry and the 3rd is a Cindi99 its definitely spreading. Anybody perhaps know what this is?

Took a head of hers to my growshop quick, it's the earlier stages of bud rot... Thank God I have a cloning project with all these strains readily available.
