I'm having this issue of rusting.i live in a coastal climate using well water..i tested the water and had a PH of 8.2(using pool test strips)i started using water from those dispenser machines at grocery stores 2days ago that water test was spot on.so im stickin with that water. but do you think the water is the issue?...never adjusted it with ph up or down because when i checked with my meter it always showed 7.0.in the soil.i now have to meters that give me diff. readings inground but read the same in ro water.1 is a digital meter(ferry-morse) the other is a needle(holdall) from home depot..also i water every other day sometimes every day beacuse of the 110D.heat and the soil i have it drains pretty quick.should i feed them more since i water frequently? i feed them once a wk
