Good ph levels

Hi there I'm a new grower and have just bought my self ph tester but am finding it hard to find the correct ph levels for my plant it's a great White shark about 14 weeks in veg now (having to LST her) does any one no what sort of levels i should be trying to achieve please?

 

Yeah will do it came with buffer solution. Presumably once I have buffered it it should be reading 0 right?

 

Yes of coarse. Apparently before using my ph meter it has to be buffered with buffeting solution. I can only assume that during the ph testers life on the shelf and In different atmospheres it picks up dust and all kinds of other shit that would affect your ph read out. So I have two pots of solution that came with the tester.
one being an acid and the other an alkali, which solution you use depends on your read out when switching the meter anything over 5 would need an alkali anything under 5 needs an acid buffer Thats what I make of it any way.

So for example let's say for argument sake that 10 was the most acidic you could get and 0 the most alkali you could get.
You turn on the meter before it is buffered an it reads 8 presumably you would then dip it in the alkali solution to bring the ph down.

From what I have been reading so far I think this is how It works, but would greatly appreciate it if somebody knows better if they could help me out a little.

What should my meter be reading at once it is buffered and how do I calibrate I know I have a tiny screw driver to do it but what is the purpose of this how will I know if I am doing it right?

Cheers G.C

 

Ok that's great thank you will have to wait until I am back home for make and model. Thanks for assistance it's much appreciated.

 

Hey yeah got it all figured out now but thanks. Yeah I really didn't have a clue what I was meant to be doing. God bless YouTube lol
