Thanks for the suggestion. I have soil acidifier sitting on top of my soil, and it's being taken down into the soil every time I water. I'm a little hesitant to water with to low of a balanced water. Because I don't want to end up with a super acidic soil after I water one day.That is quite a high pH for soil, if I were you I'd feed water of around pH 6.0, or even lower, cos then the soil would balance the feeding to a somewhat decent pH.
On my own grow I didn't notice much stress at all from transplanting, it could just be the seaweed extract powder I liberally coated the transplant holes with.
