Small update
Slowly everything started moving. After the little problems I had, everything is back to normality. I made a mistake and wanting to load the coco in final pots with some fertilizers when replanting the plants, I poured them only with water. I have two identical tanks, one with tap water and the other with nutrient solution. Well, I confused them. The plants turned yellow, but I noticed it in time. So I increased the fertilizer concentration for a while, lowered the PH and slowly everything returns to its original state.
I also want say THANK YOU to ACE
