Ph Help super confused

I added some fertz to my plant in second phase of flower, as my ph was very basic then 7.5 or so. Then I added the fertz. Happy Frog 5-5-5.
I took samples of the water running off of the soil and it is bright red. Very acidic 4.5 but when I take a soil sample it says 6.5-7. Is it because I'm using a soil ph meter on water? Please help because if it's really that salty in in trouble.

Yes soil meter don't work in water bro...go get a cheap liquid test kit,one that uses the drops....just a few bucks.

Also you should only try to oh your water, them water plant and check runoff. Don't add ph up or down directly to soil....

Runoff is what you want to consider in soil grows. Also,something to consider is that a lot nutes have buffers in them that will naturally make your pH #'s dive a bit as well as some soils.

No I added a dry fert top dressing then watered.

I had tested the PH before I added the fert. But the plant is having problems.
my plant that's in second phase of flower is getting dead curling tips on the leaves. It looked like the plant was eating itself (stored fats from ferting in the past) so,I did a PH test on it, and it was very alkine or basic @ 7.5 (the soil).

I then added the fert "Happy Frog 5-5-5" and got a PH reading of betweeene: 6.5 -7.0.( when I tested soil)

Then; I got courious, and decided to check the water dripping from the bottom of the container.
See, I figured that when I do a PH test on soil, i mix the soil with water then add the ph dye and transfer the solution to the test bottle.
So why wouldn't testing the drip water from the soil be any diffrent?

But I'm understanding that there are water "insoluble" nitrogen, phosphorus, and other things that don't mix with the water.
Now correct me if I'm wrong but is this why it's so hot because it's testing nothing but water insoluble run-off. All the edible nuits are mixed with water and stored in the soil for the plant to later eat.
