Guys here’s a quick update
5 days passed till the pots dried and I watered them again and it seems to only get worse
I made a trial and took a small amount of soil from the same bag I used for the plants and put it in plastic cup then I watered it with 8 ph water and the runoff was 5.6 ph so it seems like the soil I used was extremely acidic so that must be the problem
The whole week I was only reading in order to resolve it and this is what brought me to make this test
And on the watering I did to my plants the in ph was 6.9 and the runoff was 5.3 so it’s all just ph issue I don’t know how to fix it because it seems like doesn’t matter if I flush with alkaline water the ph seems to return acidic till the next watering

Lol yeah this is exactly what I’m working on right now
Btw in the last watering I watered with 900ppm and got 950 runoff so this is fixed only issue is soil ph and throwing all those advanced nutrients shit to the garbage I will go buy GHE you know them maybe?

Plain peat moss is naturally acidic. Plenty here grow successfully with it. They just feed with a higher ph. Sometimes certain bags of peat will have a really low ph so you feed with a ph of 8 or 9 to do a hard correction. Better quality peat will have domolite lime in it to raise ph and add Ca and Mg.
I can get coco but I tried and I can’t get the watering schedule for it
The soil is in very good quality it’s mixed with perlite but for some reason it’s very acidic and I only now discovered it I can’t find dolomite lime where I live and I really wanna grow in soil so you say the only solution is watering with high alkalinity to balance it to 6.5?
I can’t just flush it couple times with 6.5 water and make it balance on that number and after planting just maintain it?

Yes you can flush a few times with higher ph but you will have to continue to feed at like 7-7.5 ish. Again runoff ph means nothing I know it makes sense to check it but it’s no accurate. As long as feed ph is good that’s all that matters. What you can do is a few paste tests. Mix peat with distilled water. Let sit and check ph. It’s not 100% but it should give you an idea.
There’s a couple posts in forums from my country who also wonder how come we don’t have dolomite lime here and if I’m not wrong in coco you’re supposed to water almost every day and it’s too much effort for me since I work 12 hours a day
I thought of investing in r/o system
And how does gypsum effects ph level?

All this ph talk in soil really baffles me. Those plants were growing fine for a while weren't they ? I imagine yes or you never would of got so far as plant would of died quick ! That tells you that it's what you are doing to it that is causing the issue ! I once had some bad soil and plants went bad instantly ! Too much feed, do you feed every watering ? If so then stop, give just water between feeds it helps lower the salt content if you empty run off ! Do you get limescale in your kettle ? Quite a lot ? If you get limescale don't use cal mag !!

Straight peat isnt soil,its soiless so just like coco you fertigate often to runoff.
I just used gypsum as a reference that regular garden supplies arnt available.

Using too many products that are mineral based in soil you are asking for trouble in my opinion. I'm using a mineral organic mix called mills and I'm not happy with it. I'm going back to biobizz as had burn from nitrogen then instant deficiency of something else when used less. Used lots of nutrients and never liked mineral in soil but mills a and b is terrible in my opinion. The other bits I've used so far are ok, start r the root stim is ok, the vitalize silica product is top quality . Not used bloom products yet. Ordered some bio bizz grow and bloom !myself as should not have to have nonsense issues. Mills a and b is not cannabis specific, no way ! Sorry to bring all that into your thread.
organic nutrients are easiest in soil at the end of the day as no mineral to cause issues.
