new grower ph question

[MrJee]

Hello everyone, this is my first time attempting to grow a nice crop, and i have a few questions about ph.

How important is it to adjust the ph of water each time you water the plant?
will a too high or low ph of water change the soils ph level over time?
Is there anything other than water\nutes that would make a soils ph level rise or fall like air circulation, humidity, temperatures of room etc like if you were not feeding the soil anything at all?

The water i will be using is at 8.2 til about 8.5.
The ph level of the soil says 6.6 on the bag, so i watered with water i had ph'd down to about 6.5 and the runoff came out at 7.1.
Why is this?

Can i change my soils ph levels using only liquids?

Hoping to get a little better at understanding this, and how to combat ph problems, since it looks like that is a common issue amongst us newbies

It is very important to ph your water every time as nutrients are made available at certain ph ranges

and yes if your soil isn't buffered with lime the ph within the soil will change if fed incorrect ph'ed water

i would get some ph down and ph your water to 6.4 and give it a good flush with that and continue to water at 6.5
good luck

The first thing Mrjee should do is read this article on water quality from the plant nutrition series that can be found at this link:
http://www.firstrays.com/nutrition.htm

OP Read this, you won't regret it --->Understanding pH management and plant nutrition - Part 2: Water quality

This one publication should answer questions one, two and the last one.

Is there anything other than water\nutes that would make a soils ph level rise or fall like air circulation, humidity, temperatures of room etc like if you were not feeding the soil anything at all

I don't know how to quantify this, but it's been said the plant species itself can have an affect on the pH of the substrate over time.

Honestly I'd just use your tap water as is and see how it goes, if you run into any problems then think about adjusting your pH.

This is precisely my point. Better safe than sorry.

Test your tap water first. Test for alkalinity, not pH. If the OP doesn't understand, he or she should read the document that I posted.

I didnt see how alkalinity is more important than ph, as it affects ph over time.

Thanks for the link, i have read it and found it very useful.
