Nutrient lockout or PH problem?

[XLNordic]

There havent been much growth the last days and some leafs,mostly lower, has started yellowing.
It seems Ive run into either Nutrient lockdown or PH issues, or both.
Ive only been feeding them organic nutrients and i believed these are hard to overdose but i suspect that might be the case.

My cheepo 3 in 1 soil meter says PH is around 7,5 which is a little high, but high enough to cause lockout?

My tap water is hard but chlorine free and at around 7,2 in PH





Should i rinse them out with a spray pistol hose with tap water ( the easy option)
Or maybe give each pot 3-5 liters of winegar 6,5 ph'ed water?

Im not sure what and why but Ive been giving plenty of organic nutrients and addons and yesterday i also gave each pot between a tea and a table spoon worth og ash from the fireplace, which is suppose to be somewhat alkaline

Im aware that flushing with water will remove most of the microbes Ive been getting in the soil and that it compacts the soil.
But i have to stop this yellowing before it gets too bad

First of all those 3-way meters are known for giving false water readings and can lead to problems if using them. If you want to test the pH just use some distilled water and catch a little run-off out the bottom of the plant container and test the liquid.

Your organic fertilizer is not as fast as the plants want or need the nutrients. They look hungry for nutrients. If you mix a low dose of fertilizer and give a constant feed with every watering the plant will get accustomed to the ppm and start growing. As long as you feed high dose one time and skip to plain water many times the plants can get flushed to a low EC.

Using a good organic potting mix I only use water only for the first 4 weeks and when its time to feed. I use only pure water "RO or Rain water", with low dose nutrients with every watering.

I weigh my cups and write the dry and wet weight on top of the cups for the best water management. Thats all I got I hope it helps.

i have been giving them a high dose of organic nutrients and addons at least half of the waterings and then tap water for the other half and some foliar feeding also

my soil is mixed from plantbag ( with peatmoss) mix with potting soil, perlite, a little sand and like free 20% compost from the municipality
Would a flush and then foliar feeding them fix it ?

A little video update.
The water flush seems to work.
The plants are greening up again
