My soil ph tested 8.8 yesterday. Can I put vinegar on my hemp field? Will it destroy my plants? Need some help!

Are you irrigating, if so you could irrigate with compost tea which will add organic material to your soil and adjust the pH naturally. Also many nutrient product lines lower pH. So again adding those to your irrigation should be good. 6.5 is your sweet spot.
