nft system phosphorous and potassium.

had no look really in the advance section so thought i would try here.

all i have been reading is nute intake is best at 5.8 in nft system but what i want to try find out is what p.h level would be best for a plant to take in P K. the plant will absorb nutes/metal better at diffrent p.h levels

so what ph leavel is best for phosphorous and potassium to be absorbed?

The reality is - genetics plays a role.

5.8 is a good place to start. But if your plants are not happy there at any PPM then try higher and see if they like it better.

The plants will speak to you.
