Brown spotting around leaf veins.

Started getting brown spotting a few days ago, is progressing more but is staying around the veins of the leaf with some yellowing starting on damaged leaves . Wondering what is wrong.

Using Sensi Bloom part A/B with Big Bud, Bud Candy, and Cal-Mag due to soft water. in Fox Farm soil, getting a constant 6.5 ph in water at around 800ppms. Cal-Mag+ is given every watering at 15ml in a 4 gallon bucket. Feeding every other watering. on day 28 of flowering, using a blue-lab ph combo calibrated regularly. Haven't flushed yet

Maybe try feeding a little heavier with the CaMg, and watch for a couple days. Don't flush. Almost every time I've ran FF soil, I ended up with some yellowing. They don't mix enough lime. Ideal soil ph is 6.8ish. So if you're nailing that, or there abouts, you're doing the best you can. If you are feeding every other watering, keep it around 1100-1300ppms max, and you should be fine. Consider mixing your own cooked soil next round. You won't be bummed.

It's not the soil, it's not Ca, you don't need more N!

To much P in bloom to early.

Its the Big Bud......you should not use a high P bloom booster like that, unless you know how to actually use the NPK ratio for the benefit of the plant.
AN lies about how and when to use it's nutrition for the best results.
AN makes to many products, designed to drain your wallet all the while draining the strength of your plant.

^ Listen to him. I've never ran AN nutes. Too sketchy for me. I try my best to keep it simple.

Yah after this run im done with AN for now been using the bagged TGA super soil for my out door and its been doing damn good or i might try earth juice.

forgot to add
I just started feeding them bloom and this started before i started bloom. Before i was just giving the AN sensi - grow and Cal-mag

What should i do then do i just skip feeding for a few and just water?

Thanks.
