I'm struggling with what looks like a calcium deficiency in my "just add water" setup. I think this is because I didn't realize I was using de-mineralized water, not spring water, which is what I thought it was. Doooh! I've since been searching for a source of spring water or even just mineralized water with a Ph between 6.3 and 7.0. So far I've come up empty handed. The closest I could find was a supplier in a nearby town who sells "mineral water" with a Ph of 7.1. In the mean time I picked up a Ph pen and I've been using tap water with a natural Ph down from Blue Sky Organics. The first time I took it down to 6.0 because I thought it was a zinc deficiency. Then I discovered calcium won't be taken up in that range and I started to see more dead spots on the leaves. After that I watered with Ph 7.0 adjusted tap water. That was two days ago. No obvious improvement yet. I'm seeing it on the other, smaller plant that didn't have it before I corrected the water but this might just be from the Ph fluctuation. I'm nine weeks in and I'd like to flip to flower but I'm compelled to wait 'til I can see some improvement. My question is: does RO water permanently trash the supersoil ecosystem or can it be restored?
