You might want to mix 3:1 RO/Tap

To be factual.
You can't tell SHIT from a cpl of leaf pics!
Pic of the whole plant.
The effected area
Close up of the area - Here the leaf pics do help a bit.

I suspect that your heavy pounding of a bloom feed is giving you a starting P tox condition....Can't tell, can't see the whole plant.

At what rate are you using the cal-mag at?

 

[SDK420]

Every other week i add about 200ppm to the 0 ppm water

1500ppm 3 times a week? that's your problem

How would ypu feed 10 gallons of coco, with a plant that drink 2 gallons of water every day? Just a rough estimate

[polishpollack]

your ppm is a different matter.
you could probably cut that ppm to 1000 or less. those fert molecules are probably binding to the coco. is the water loss all being consumed by the plant, or is warm temp causing evaporation?

 

[SDK420]

Water is being consumed. The plant with nute problems drink like a half a gallon a day and the are both in 10 gallon containers and the same size

The one that looks good is the one i barley feed lol

So do you think feed 500 ppm every other day? I suspected ive been overfeeding.

I also have hypoaspis miles

Over feeding - salt build up in the coco....

Do a salt leech to the coco (flush) and reduce the ppm's to 800. Raise it if the plant shows a need for more.
Ca/Mg at 7 ml. Use the Ca/Mg in the leech water too!

How often should i use the cal mag and thanks, i thought i was overfeeding i just wanted to confirm it

In every watering by the dose written on the bottle.

After the initial charge of the cations, CNS-17 has enough calcium in it. Coir does best with a balanced nutrient make-up, fed at least once a day. Keep it moist, never let you're coir totally dry. If it's more pith and peat than fibers add some perlite. I rarely have to feed over 600 ppm or 1.2 ec.
My larger plants I do in 5 gallons almost always require at least 1 gallon a day through multiple feedings
