Weird yellow brown spots on leafs. 10th day in bloom. Recirculated cocosetup

[passion]

Hi

Im day 10 in flower and have some weird looking spots on the leafs. Getting worser. Saw it first time 4 days ago.

Running clones in straight coco with full canna schedule. Its recirculated dripsystem.
PH is around 5.8 but sometimes i have to adjust it. Always try to have it between 5.4 and 6.1.

Here is picture.

Hope anyone have an idea!

Can you post a better pic?

I can't really see any detail on there. My first guesses would be pH, calcium, or pests

Where on the plant is this happening? Can you get a pic of the whole plant?

Will you fill out Stitch's guide?

I use straight tap water and i get that sometimes...
I think its calcium / magnesium defect..

Have u tried Epsom Salts..??

I agree with 'tang--thought I was tooooooo high(is that possible?)to focus on pic
I have that same looking problem on well water
I was told to get a reverse osmosis water filter setup
Running well water for now --
good luck
