First Grow Ever

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.
