Moved them up to their final home (8gal pots). I amended pro mix hp with:
2tbsp/gal of Gaia green bloom
1tbsp/gal of Gaia green 4-4-4
1 tbsp/gal of Gaia green rock dust blend
Watering with:
20mL/gal of terpinator
8mL/gal of diablos monster carb
PH to 6 - 6.5
I'll switch them to 12/12 after roughly another week to let them stretch their legs a bit. They both look perfect. No deficiencies or issues. I'll take some clones from each before switching to 12/12.
