Hey
@CaptainCream!
I'm growing OG Kush on coco. You can take a look by yourself on the week 3 and compare them.
OG Kush is a relatively small bush, with fragile stems. I think they're doing great, they got a great colour and size.
Just as tip, be careful about how much you feed them. As I have experienced they eat just a little until they start stretching.
