Fast Buds Purple Lemonade FF

Went away for 10 days and these plants exploded with growth. I watered in very well with pHed water before I left. I set up a watering system with 5 gallons of pHed water and hooked it up to a WiFi outlet. I was able to water twice while I was away using this. Obviously nothing bad happened while I was away. I HAD to top these girls because I never thought they would have grown so much in a week. Unfortunately, i usually do not top right before I switch to flower but i did the day I switched because i need to control the height. Still no nutrients thus far. Will amend the soil with a flower booster next week.
