So i did little more testing here. This is my first grow so im am experimenting a little.
Firstly i only topped 1 of the Imperium x and the Euphoria.
I only defoliated the topped imperium x.
The one Imperium x which is a little shorter than the rest had nothing done to it.
I am not that consistent with nutrients since i dont water by hand, but by dripping. I give nutrients like 2 times a week in a small dosage.
