Both FS#3 and FS#4 are doing great. I still learning and before I explore any training techniques or topping, I just want to see how the plants grow. I've also been considering pruning but I'm hesitant as a newbie.
Using General hydro 3 part flora nutrients: Grow = 3ml/L, Micro = 2ml/L, Bloom = 1ml/L, CalMag = 1ml/L.
