    Water my plant and 2 days later she has some brown spots turning up. Ironically it’s the first time I’ve ph’d the water. She’s 2 weeks. Next watering I will test runoff ph but any ideas?

    No I I just planned on adding some salt to my water. I can get cal mag if that would be better

    yes it would be.!!

    the spots will not go away, but you don't want more to appear, so just give enough cal/mag that the spots don't get worse.
