Brown rusty spots? Calcium def?

[0ddj0b7]

Ive got some type of brown spots that seems like calcium def but i feed with calmag every watering and i also have well water that's 7.0/320ppm out of the tap.

Of 2 outdoor plants this is the only one with these random spots. I want to say i noticed it on older leaves first.

Im about 4 weeks into flowering, 10g air pot with organic soil plus amendments. Also feed fox farms trio every other watering.

I can't seem to figure it out and I'm thinking it's some type of fungus.

Im going to try some organic fungicide. Will let you know how it goes

Edit, also i remove affected leaves regularly and hsve moved one plant away from it. Now that i think about it i believe I've saw this issue on the leafs in the trees in my yard so possibly that's where it could have came from

Good luck.

It's just effecting lower leaves mate, bottom two node

I don't see much of a problem, the new growth looks good, slight nuteburn, a little to much N. So I know she's been well fed.. Bottom leaves are expendable..

Ya hmmm that looks like something I've saw before but I cant remember. Did you disturb the roots at all lately?

Mine seems to be doing much better now! Don't see many of those spots or any new ones developing.

Same thing was happening to me, you're actually giving to much cal mag. Id say cut your cal mag for about 3-4 feeds and just give em your base nutrients then when you introduce you cal mag on the following feed half the amount of cal from what you'd normally would do and only incorporate cal mag every other/2nd feed.
