are you over watering? that can cause a drop in ph with soil if it becomes too wet....making leaves droop and lockout available nutrients
stra8outtaWeed Reviewed by stra8outtaWeed on . Soil PH too Low Hello first post on this site. I am a newbie outdoor grower (green house actually). The PH of my water is around 7.2. My soil PH is around 5.5. My soil consists of CA Supersoil, Vermiculite, and Perlite. I use Jack's Classic 20-20-20 every third watering. Some of the big fan leaves are starting to droop a little and are slightly discolored. I'm sure this is the PH issue. I have read about adding hydrated lime but to raise it but that it can also be toxic and bipolar for PH testing. Rating: 5
