That's fine if that is the table culture and everyone is familiar with that culture. For a player who isn't familiar with the table culture, it could lead to culture shock and assumptions that the DM is a "gotcha" DM.
I'm a "gotcha" DM, and until I'm familiar with how another DM works I assume the same of them and play accordingly.
Put another way, if you're that new to that table it's best to start by erring on the side of caution.
I, personally, have found in the past that it engenders an atmosphere that doesn't match the way I or my friends like to game. We prefer a friendlier atmosphere.
Not related. We're usually the best of friends at our table even in a "gotcha" game.
Hence, I will typically give them reminders and warnings if they forget a pertinent detail of a spell. Some of these guys, including myself, have been playing since 1e or 2e and have multiple versions of spells rattling around in their skulls. Others are complete newbs, for whom this is their first RPG. It's something the character (who has studied magic) should be aware of, but the player (who only pretends to be a mage for a few hours a week) might have made a mistake regarding.
Also not related, really.
I'll also remind people of how something works if I realize they've clearly mis-remembered it, or at worst will give the character a roll to remember in cases where the character is smarter/wiser* than the player.

But with something like a wish, if you ain't careful, sometimes it's gonna bite you regardless. Much of this depends on the wish's source - in my game last night, for example, during treasury division the party had to sort out a ring which they'd determined, through a nicely-done series of divination spells, to contain a somewhat malevolent wish - almost like a really elaborate trap.
(example: if the ring-wearer wished for one or more physical objects those objects was liable to appear
inside the wisher's body - and just think of the mess that'd result if someone wished for something big like a castle or an elephant!)
