It's hard to burn plants with cfl light. It is pretty mild, but grows great plants. What you've got going on looks ok.

You could bend those wings out a bit, so they are directing more of the light downwards.

The twisting is sometimes a reaction to the environment. What are your temps/humidity?

Yeah. I like the way it makes my plants develop early on. Just tall enough. Still bushy. I don't use it for very long.

29% RH is too low and 80% is too high. Are you experiencing this swing daily? What is it during lights on?

when lights are on it RH sits around %60-65 . Yeah its cold in australia - if i zip the tent up it gets warmer but i was starting to think because no fresh air that was the cause of the twisting.
