Holes forming on leaves

Because in soil, the acidic salts remain in the soil more so than in hydro setups, causing a lower-pH situation. Thus, soil grows require a higher pH going in.

Note that each number on the pH scale is an exponential order of magnitude. A pH of 5 is 10 times more acidic than a pH of 6. A pH of 5 is 100 times more acidic than a pH of 7.

Have you ever seen this put holes in the plants? Like the pictures that I took of mine. Just scared because I’m about to flower

I’ll be honest, looks more like wind damage to me from leafs rubbing against each other. I’ve never worried about that. But pH can get things twisted

Personally, no. But I most definitely trust @Renfro. He suggested it could, so I'd take his word on it without a second thought.

Whatever you do, only change one thing at a time until you see if there are any positive and/or negative results. If you change more than one thing at a time, you'll never know what fixed the problem, or made it worse.

You’re saying my ph is to low and that’s what’s eating away at the plants?

I wager that if I stuck my Apera or Bluelab in your soil that the pH there would be lower than you imagine, low 5's, even 4's... Soil accumulates the salts from the nutrients and the pH crashes over time. If you can quantify the pH of the root zone (not the feed) then you can really correct matters. I posted a thread on root zone pH correction, https://www.rollitup.org/t/medium-ph-correction-soil-and-coco.1000514/
