half a flush

ok i think i have a ph lock out issue and i watered and tested my run off it was 5.8 to 5.9.the plants are in 5 gallon buckets.so i flush with 4 gallons of ph`ed water of 6.8. SO MY QUESTION IS THIS CAN I FLUSH AGAIN IN A FEW DAYS WITH SAME TYPE OF WATER SAME PH OF 6.8,AND WILL DOING THIS RAISE THE PH OF MY SOIL BACK TO A ACCEPTIBLE LEVELS.IF NOT CAN I ADD SOME DOLMITE LIME TO THE TOP OF MY SOIL AND THEN FLUSH THROUGH IT WILL THAT RAISE MY SOILS PH.

I use dolmite lime to bring down the water PH for my flood and drain system. Apparently the ideal PH is somewhere between 5.5 and 6. The lime will bring the PH from 7 to 5.5 as an example. Make sure you don't overuse it. The effects of dolmite lime can be lasting in the bed.

I just keep posting nothing until i can get an answer

No i`am in soil ideal ph for soil is between 6.4 and 6.8 for all nutrients to be available and right now my run off is 5.9 6.0 SO I WANT TO RAISE THE PH OF MY SOIL
