Ive got a plant in day 21 of 12/12. using FFOF soil. My water going in is 7.2, run off is 5.9. What do i need to do to get the ph back up to 6.8. I flushed with FF sledge hammer. Didnt make a differance, still comes out 5.9. The plant is not showing any sign of deficiencies, yet. would like to try to get the ph back to 6.8 so i dont have problems later. Thanks for any help.
