I wouldn't have thought the higher light output would be a problem its not one I've found just watch the extra heat is all. Guessing you're planning to start it further from the plants than the 250 was and then lower it to a comfortable level anyway which I've always found works for me.
Best of luck with the grow anyhows.:smokin:

The jump in lumens from 250 to 400 watts will not stress plants. And likely a 400watt light is a warmer red...which the plants would all too happy to utilize.
