I say fire up the HPS if you can manage the temps - the light intensity will be better.

Looking at the pictures, the leaves are perhaps looking a shade light (unless it's the exposure), perhaps a little bit more feed (grow) would green them up a bit!

Hope this helps!

No worries buddy! I'd start feeding right now!

Looking a little hungry! ^_^
Go in light with the feed , it doesnt take much to perk them up!

Also while i'm here lol

Do you have a fan blowing in there?

The bottom leaf on the bottom left plant in the picture - you see it rolling up (in on itself) at the sides?? That means it's too hot. A fan blowing accross the top can often sort that out. ^_^

What you think 18/6 of light will do??

18/6 will do fine! As will 20/4 or if it's a true autoflower - 24 hours should be fine too!

Some people see no difference in the extended hours and believe the plants benefit from rest. I've tried them all and don't see any difference!

Temps are good - Humidity's good for veg!

Presuming you've got extraction and the air's getting exchanged - it sounds about perfect
