Confused Lazy Grow

Day 30 toady, i switched to 12/12 3 days ago e the babies are already stretching hard and some are showing preflowers i'm pretty happy i'm watering with no nutrients as i'm using Canna Pro Plus soil and it should have enough nutrients for the first 3/4 weeks of flower. I cleaned the bottom of the plants from lowers branches and leaves and i will continua till day 14 of flower and i fixed it with a bamboo stick i got gifted from @AlpineGoat i will fix the other branches in the next weeks i'm pretty stocked with this grow this genetics are really solid growing strong and fast! Good job @Exotic_Seed!!🙌👍
