AF COB soil problem calmag ?

They have been rotating already
My tap water was around 500 and is very hard so there should be a decent amount off calcium and magnesium in it already normally

A big difference is my watering.
Normally i fill up a big box with water and take the other plants and place them in the waterbox. So the roots become very wet and the soil beneath absorb it very good.
Now i just poor it over but i also made runoff boxes for each plant.
