31°C is pretty hot - especially, I would think, for seedlings. And I would consider a 1000-watt MH to be overkill for newly "hatched" seedlings unless you have several dozen going and require the area-coverage of a 1kW MH set at a higher height than what you would be running it for normal (established plants) vegetative growth.
Of course, I'm not the kind of grower that gets into an extreme hurry right off the bat, I don't advocate killing a fly with a howitzer when a fly-swatter will do the trick at a cheaper price, and I believe in waiting until the plant is (sexually) mature before flowering so trying for extreme growth right off the bat would be counterproductive for me. YMMV, of course.
