So I have been running irrigation water in my garden. I noticed last year my foliage yellowed and fell off. This year things started to yellow a little bit early. So decided to check my ph and it was 7.5-8. Way too high. I have some dolomite lime in the soil, but I think this may be my cause of yellowing. Because my plants are on a drip system with a fertilizer injector, any good ideas to pH the water? There's no Rez I can adjust pH in. Should I top dress a little more lime?
