I'm pretty much stumped. All I can do is say I SUSPECT that some of whatever was causing your tap water to be up around 9 is still in your soil.
I would not take the nute solution much below 5.0 (I believe sunshine mix is technically soilless; if it were a soil I'd say 5.5) even if your soil IS showing high pH.
You need to lose that water source entirely. If it means going to distilled or RO with calmag, or getting jugs of tap water from a friend in another town; hell, even RAIN water that you've adjusted the pH on would probably be better, lol!!! (I'm kidding about the rain water... but only partially)
There's a product I've used to flush stubborn soils and save plants; it's called 'soil syrup' and is nothing but Humic acid from Leonardite. It buffers in the proper range for cannabis. I'd use a flush solution of purified water with the soil syrup added at 1/10-1/8 the strength recommended on the bottle.
This is a really unusual situation. You may notice reading around here that the vast majority of pH problems in soil and soilless grows are actually that the soil is too LOW.

Well it fucking Rains here 9 Months out of the year...LOL what about just like filtered water? like those brita things that use carbon? I would love to go RO but i need a carbon filter bad and i would hate to have to use the money for that to get a RO system.

I've thought about maybe getting a garbage can and filling it and letting it sit...Would that help? Could it be i maybe mite not be letting my water sit around long enough? Alot of times i pull it out of the tap and then adjust within 5 minutes.....BUT my roomate has mentioned that hes scene the PH actually go up after sitting around at times....

Faulty Meter? Fuck i just bought it and calibrated it...It's a Hanna and it wasnt cheap and when calibrating with solution i didnt even have to adjust it was already on point....

What to do what to do.....On the bright side though alot of the plants look fine im lost.
