EVs

[Tomatoman1]

Hello.
I was EV training some pokemon for the first time and I screwed up. I took 4 pokemon with me and of those 4 needed 3 perfect EVs in Attack. Before that, I was giving one a perfect EV in HP, but the other ones got it too. Is there a way to delete those HP EVs?
Please help and Thanks!

You can use a reset bag in super training or certain berries that lower the base stat.
