If you cant get it below 30 I take it that it's going over 30 quite a bit?

That is quite hot, you need to drop the temp by 5c or so, maybe get a bigger fan in there?

They are quite squat, but thats prob. because they dont have to stretch at all to get the light which is a good thing. You could drop the plants a bit lower and they would grow taller.

Give it another 5 days or so and start flowering.
