Why u gelly by solfire gardens

So these girls are doing well.i have been useing tap water with declorinate. i just took it easy with only one base nutrient feeding and then the rest just clean water then i used all my microbes and made a tea.i will be switching over in a couple days.i want those microbes to do there job so i can switch my feeding to flowering.these pictures are from a few days ago and i just stripped them of all of leave and small branches.major defoliation before the flip.now that magic happens.i let them all get about 15 to 16 inches so they dont get to big for the tent after the stretch.
