Still use zym and rhizotonic. I'm adding some bat guano on new soil, seem perionyx works well with the bat. And canna zym is very good with the soil. I usually add canna zym when watering, and rhizotonic when i chang the pot (0.8 ml/ litre)
Some little dyna 9-3-6 twice per a week work good with plants.
All the girl in bigger pots will enter the 12/12 light time soon! Then others will veg for more few days.
