They both stop growing and Smalls(60cm) is bigger/taller than Biggie(50cm), but is a little behind in flowering with smaller nugs. I heavily defoliated both of them. I use 1/8 of the nutrients feeding guide and they are still way too burned.
@Rollin, Well it does have it's smell, but if you are using a carbon filter with induction fan you are goot to go. If you do not have this you can buy Ona Gel. Depends on your grow. PM me for more info.
