Some pics would be helpful in diagnosing the problem @papichulo Welcome to the forum

Promix really has no nutrients , what are you using for nutes? Do you have a pic of the plant?

And for clarification when you say soil @papichulo are we talking your own garden soil, or soil you purchased?
Reason I ask is half of those who post Soil here are actually using a mostly peat moss type that is often mistakingly refered to as soil.
Peat seems to act more like Coco Coir and as such many are given the wrong advice by giving their medium as soil.
Brown spots are usually Calcium related but without pics no diagnosis can be made properly.
Gaia green nutes/ compost teas,pics i will post one light cycle comes on in 2hrs thanks for the help ,this is my second grow.

That is nitrogen toxicity. Your plant is overfed. Are you managing runoff pH and PPM?
I can see a Fish Sh~t label there. Overuse of microbe products can also cause burning. It may be a combination of overfeeding and the Fish Sh!t.
I also expect your pH is very low.

Awesome,i will just start on straight ph water/ i dont manage run off, i soil test.
You should be. It will prevent issues like this from happening.

Or should i flush, wont that remove my microbes i have in my soil
It’s hard to say without understanding your runoff pH and PPM.
Microbes are easily replaced.
Id just water the next few times with a little more runoff and monitor new growth. Definately check your ppm and ph. Do a slurry test for more accurate results. Let us know the results.

So i flushed plants, got the ppms down to around 700 and tested ph of run off, going to hit the with Recharge and some liquid nutes ph to 6.5 and 1100ppm, any other things i should be doing.

To me it looks like a calcium deficiency. Are you using calmag? The leafs are dark green and def loaded with alot of nitrogen but atleast the tips are not burned bad and there is no clawing i can see. I would cut back on the nitrogen or grow nutes and get some calmag. I see your in flower to, too much nitrogen can really impede bud growth.
