You have to use calmag in coco. But I'm having a really hard time interpreting what you say you are using for nutrients.
You're using Celsius and referencing some products I'm not familiar with, just out of curiosity what part of the world do you live in?

They will survive. This is a very common thing that people don't think of when using coco for the first time. I was guilty of it myself the first time, too! Some lower leaves will drop but you will be okay.

now I come with an update about my plants ... having problems with calmag having no other solution I washed the roots of the plants 3 days ago only with PH7 water and after 2 days I added in 1 liter of water
3ml phosphor plus
5ml hesi bloom
2ml bloom bost
and wather again it start to look better but im not satisfied
yesterday I received soilmeter and I was shoked when I saw that the soil has ph 5 at the moment. I use the flat water from the store has PH 7.5 after adding nutrients it reaches 6.5 but it is not enough to increase the pH of the soil you have other ideas to increase the ph unthil my PH- solution come please leat me know

After you mix your nutrients set the pH in the water jug close to 7 to offset the sour coco and try to get the water coming out the holes of the pots (=runoff ph) to right around 6-6.5.

One thing to try in the future that has worked well for me is to mix about half of your dirt as compost. Pure coco is good for setups like drip-to-waste but if you're just hand watering in pots, having a bunch of compost in there makes the soil more stable over time and this is what I personally swear by.

Still use some calmag though! I hope it gets there soon! : )

i washed the roots with 10L wather with ph 7 also with nutients but the f*ucikg soil have 5 fuc*nk PH i just don`t .... FU.K!!!!!!! WHAT I do not understand is ... I put in a jar 10 l cocosoil I measured the ph, had 7. I added simple water with ph 7.5 the acidity of the soil decreased to 5 PH even to 4PH how to explain this I do not understand anything ... im going crazy WTH??? i will never use coco soil

Have you do7ble checked with a different measuring device such as a real pH electrode (different from a soil probe, usually glass or epoxy) or with indicator drops?

i'm thinking you didn't rinse and buffer the coco with calmag if using a lower quality coco or bricks. what brand of coco are you using?

I personally rinse my hydrated coco till the run off is pretty clear then "charge" it with a mild nutrient solution for 24hrs., drain off the "charge water and spread out on 3mil plastic to evaporate excess water. Then I mix pearlite in at a ratio of 30% whatever my total volume.
On another note I'm a firm believer that if you using coco coir especially that you need to feed your mycorrhizal fungi and microbes. I use URB(www*URBnatural*com) and Green Eden concentrated soluble mycorrhizal fungi. Advanced Nutrients Carboload (Amazon) for their food. They break down the nutrients to make them more available to your plants. Hope this helps out

This is excellent advice right here

Hey there! Bear with me, I'm just waking up.
Some cal mag products contain Nitrogen. You could be unwittingly adding N into flower cycle.
pH- it's a pain in the rear at times! The best thing I've found to do is save those water jugs, fill them from my tap and let them set for 24 hours minimum. I know we're in different locales with different water treatments but water is full of chems that aren't beneficial to much these days.
Lower ppm a lot. Back way way off. Lower ppm to almost nil. 200-300. You should flush with only a cal mag additive at this point imo for 1 week and reassess. You're not going to see any recovery on the current leaf damage. That won't happen but the creeping damage will stop once the errors and deficiencies are corrected.
When you flush your plant you're going to go for 50% run off, some say 100%, but really it doesn't look that bad. Normally you'd only want to water until about 20 percent comes back out, that's runoff, what comes back out when watering. Make sure your temps are good, the rh is good and don't let your pots sit in the run off. Test samples of your run off if you've received your pH meter. A cheapo meter, $10, will get you through if you store it in calibration solution properly. Keep that glass bulb clean and covered in reference solution in a little jar, not the pen cap it comes in. Use a jelly jar or something that's been properly cleaned, steamed ideally.
Let the medium dry. You can tell how dry the medium is by lifting the pot. It shouldn't weigh anything. Try not to let your leaves begin to droop though. You'll want to keep proper levels within the plant. You don't want it bone done dry and sucking everything in that gets introduced in the next watering immediately.
How many weeks in are you now?
Have you done foliar sprays or spilled water on those leaves? Do you treat for bugs? I feel like there are fungus gnats about as well.
I hope I helped some... Good luck man. I would seriously start a calmag flush.
I'm not sure where your pH should sit. Hydroponically Coco would be low, 5.5- 6.2 can be normal but you've got compost. I would take one plant and use it as a tester. Drop pH to 5.5 on it and see how it responded. That's just the things I would do and the whole ship could crash because of it. Good luck dude!
