Ppm and ph run off, why is it so high in my soil

Why is my ph in my soil so high it is 7.9 and another is 8.0, the third one is 6.9 and last is also 7.9. When feeding I keep it 6.3 to 6.5. Also my ppm run off is 1400 in 2 strains and 800 in the other. Are some eating faster than others but y is the ph so high, and i would like some input on nutrient lockout.
