Do my plants look ok?

[THE BEAR]

First time using hps 600 w and would like some reassurance that my plants look ok as I'm only at around 50-55% RH , ,Just worried the humidity might be a problem, but I've been told it should be ok so I will pay a few pics and see what yous think, any help and or advice would be greatly appreciated

This one's very compact and tight together with lots of growth, will it spread out more ?
