Advanced ph soil issue

Here it is. PH of my grow soil was around 6.5 when I first started grow. I added some Vermiculite and nutes in my fourth week, and the PH went down to 5.8. I live in a country where it is hard to buy stuff (we dont have grow shops and such) so I was thinking about increasing the PH of my soil by increasing the PH of the water I use to water the soil. 1st question:

Is that even possible?

2nd question:

I got my a buffer 7.2 for aquarium that contains phosphate. Its used to balance the aquarium water. If I mix that with my mountain spring water (ph 6.6) and water the soil, will that increase the ph level of the soil?

i appreciate any help! please, Ive been trying to find an answer to this for weeks.

Stay away from the aquarium buffer, because phosphates aren't good for your plants. If I were you, I'd flush with that 6.6 water, until the runoff comes out close to, or at, 6.6. It'll hold there for a few weeks, then you might have to flush again, to bring it back up within range.

Do you have access to dolomite lime? Many stores have it, not just grow shops.

...rapid release dolomite lime. Google it up.

Damn, money wasted on that damn aquarium buffer... Dolomite lime it is! But how do I use it? mixing with water or just mixing it with soil and then watering... and btw, do I need to flush the soil if Im gonna use dolomite lime?

...in pots, add 1 tbls per gallon of soil as a top dressing and water in as normal. Flushing is not nec. Good luck.

And that will raise the ph ???

...correct. Dolomite lime has a pH of 7, or neutral. .....lime will not lower a high pH however, it will only raise a low pH.

Thanks for that bit of info, as it was something that I wasn't sure about.

but i read some place that if you have used any type of nutes lately that it is a bad idea to use lime to bring the ph up... it causes salt build up?? is this true?

...imo, if I were you, I would stick to all organic in soil, I've never had salt build up issues.
