Has anyone tried DIY hydro nutrients?

I saw a recipe online for mixing your own hydro nutrients with Epsom salt and other basics. I gave it a shot, but growth wasn’t as strong as with store‑bought mixes. Has anyone had success with DIY nutrients long‑term?

Yeah, one time I gave DIY nutrients a shot, and my lettuce basically staged a protest! Tiny leaves, slow growth. Once I went back to store‑bought, it bounced back like nothing happened.
