This is my very first grow of my first clones, grown from C99 seed by a lovely friend -- my many thanks to the generosity of @FairyBudMother for the clones and patient guidance.
The Girls look good today. They were transplanted from airpots to their large growing pots with added mycorrhizae on 6/24. I watered for the first time (~1/2 cup plain water each, per instructions) yesterday (6/26), and the plants are distinctly perky today.
I measured my tap water on 6/22, finding the 5.86 (PH) & 186 (PPM) sufficient to use without tinkering with it. So far that seems to have been a fine choice.
