Creme de la Chem

This week the plants got very bushy and wide. Stopped using Root Juice and Used Recharge microbes for the first time one day out of the week. LST also began this week. I noticed separate issues on two of the plants on their 21st day; the girl on the right showed some yellow color in some of the tips of the new growth at the top of the plant, while the girl in the middle had low hanging leaf tips which look burned / discolored. I think I might be over-watering. I'll confirm all of their soil is completely dry with my a moisture meter before watering next time.
