If he actually is solid folding pre isn't bad at all. You semi-bluff when you are trying to win the pot because you have fold equity, but have equity if you're called, so if we raise turn it's because we think we can get him to fold BETTER hands. pretty much the only better hands we're folding out are pp's, and it's doubtfull that he's going to be barreling with that part of his range. I think this point pretty much holds even more true after he called your flop bet. Only real reason to bet the turn is as a blocking bet, in which case I think your bet should be about 2.30, and obviously it's a fold as played.
