How to stabilize the PH?

Jalbit said:
if the correction is in the range 0,1-0,3 nothing to worry about.
Your ladies are too young to make any correction. Wait until the next res change and see what happen.
Try to follow this schema.

I don't know why the leaves are turning inside like this. PH almost 5,75 EC 710ppm water temp 25ª they have about almost 3 weeks they are watered 15 minutes hour a hour. Everyday the PH changes 5,75 to 6,75

Potassium silicate will help a lot to keep pH stable and cause good cation exchange. I aim for 20-30ppm of silica in solution.

You have products like Protekt from Dyna Gro or Agsil16H if you want salt based and make your own solution.

We have "Kaliwasserglass" locally, that's 36% potassium silicate in solution. Used for impregnating concrete. I think Protekt is 10% Si if I remember correctly.

You want it to drift between 5.5-6.2.
If your ph falling to fast you are probably over feeding them, if its rising to fast you may need to feed them more, that chart above is very helpful.
