What do you think is a safe ppm, about 25ppm potassium?What I consider more important is not to overdose potassium. It may cause imbalance among potassium, magnesium, and calcium uptake by plants.
What are the water parameters? GH/KH ? Substrate?I want to start using KCL as a potassium source.
But I see that I am also adding Cl to this. Is that harmful?

Don't have water parameters yet. But I'm going to use ADA aquasoil, lean-dose approach.What are the water parameters? GH/KH ? Substrate?
No problem using KCL but it truly will add lot of Chloride if you going for 25 ppm K, this is extremely high for both K and Cl in my opinion.
I believe there are endless topics on this same question which are already covered here on this forum. @_Maq_ can probably send you in the right direction.Don't have water parameters yet. But I'm going to use ADA aquasoil, lean-dose approach.
But why is that too high? If you use the EI you'll have between 10-30ppm potassium. And according to the ADA approach (lean-dose), the potassium goes up to 25ppm
I would use KHCO3, this is same as using ADA Brighty K, Easy to find and replicate. The KH coming from KHCO3 will be neturilized by ADA soil.Perhaps use K2CO3
Frankly, I've asked myself that question many many times. Why do they recommend so much potassium?But why is that too high? If you use the EI you'll have between 10-30ppm potassium. And according to the ADA approach (lean-dose), the potassium goes up to 25ppm
Yes.Perhaps use K2CO3?
