Hey guys, hoping for some Christmas Eve advice.
I have 4 different varieties of autoflower planted in 5 gallon buckets, all using the same potting soil I bought at lowes.
The last week they've started going yellow, and a different variety that I planted a week after them has actually surpassed them in size, because I was growing it in some soil I'd already used from a previous grow.
I tested the pH of the runoff from the buckets I'm having issues with.

As you can see, wow, it was high! No wonder I'm seeing issues, they are probably having issues with nutrient uptake with the PH f'd up.
I typically water with filtered tap water pH'd to 6.0
I used a large commercial spray bottle, mixed up some water at 5.5. I used a cup to cover each plant and I misted the soil down really heavily with the water so it was nice an soaked, that way it wouldn't just run through really fast. Between the 4 pots, I went through about half a gallon of water. My though process being to try to gently bring down the soil pH, I didn't want to shock it too quickly.

I now have much greener plants, but all of the leaves are curled up like that.

Did I shock them with too acidic of water?
They do appear a lot greener than yesterday, so I'm hoping maybe I am on the right path to fixing the nutrient uptake issue?
