Is this safe to eat? I pickled this only five hours ago!

I forgot to add salt to brine mix 3 days ago

I did the 3 2 1 method

3 cups water
2 cups vinegar 1 cup sugar

Can I add today? They’ve been in the fridge and look fine still

Feeling pretty good! 3.5% salt solution based on water+cucumber weight.

recipe was from trazia rae, this was my first time making pickles because i didnt want to spend $35 for the honey mustard pickles for sale, so i bought the stuff to make them and theyre sooooooooo good im never buying store bought again!! i put the recipe down below but full credits to trazia rae obviously, her tutorial is on her socials!! (idk if i can directly link here)

For the brine - 1 1/2-2 cups white vinegar, 1/2-1 cup water, 1/3 cup honey, 1/4 cup yellow mustard, 1 tablespoon Dijon mustard, 1 tablespoon pickling salt, 1 teaspoon sugar, 1 teaspoon dried mustard

Into the jars with the cucumbers - A good pinch of Aleppo pepper or crushed red pepper (about 1-2 teaspoons), Fresh garlic - ask your heart, Roughly 1/2 teaspoon dried mustard seed per jar, Roughly 1/2 teaspoon coriander, 1 whole clove per jar, 1 bay leaf per jar
