about how much PH- is good to add if 10 liters of water and need PH down 1? 2ml PH- for 10 liters?

I’m not familiar with aquarium ph downs so maybe stay clear in future. Lemon juice is a decent alternative if you can’t get your hands on any from a hydroponic shop.
Flush your plants through with ph’d water (not the aquarium stuff though) and quarter of the stated dose on the bottle of nutrients.
When it comes to using ph down etc don’t go by ml’s but add a little at a time and check the ph as you go to be sure it’s going in the soil at the correct ph. You want to ph after adding the nutrients.

As said above that's seems like a hell of a lot of PH down, you calibrated your pen recently?

I am using these drops (sera drops) to test the PH of the water. I think that need to buy this PH Pen but if I remember right, then the drops are more accurate and no need to calibrate anything.
I think I will pass the flushing this time because its 9 weeks and the flushing will shock the plants for many days.

I don’t think drops would be more accurate than a decent calibrated ph pen but they’d do a job at least.
It’s upto you, they’re your plants, but imo the stress of not being able to uptake nutrients is no where near the stress of a bit of over watering. Especially when it will help them cross the line. And by the looks of it you have at least another 4 weeks to go.. I could be wrong on that, but I’m just going by the pictures.
All the best

If you don’t want to flush I’d suggest just water only the next couple of waterings ph’ at 6.0 and see how they go after that. Maybe use quarter/ half strength nutes after you’ve done the water only.
Would also be worth reading up on some basics for growing cannabis for any future grows, that should prepare you for problems like these arising again.
All the best
