how can i adjust my soil's ph?

i have 3 nyc diesel seedlings that are starting to develop nicely. i have a ph & moisture meter that i keep stuck in the soil just so i can see how fast my soil mixture will lose moisture.

anyways, my ph is showing to be around 7 to 8 on the meter and i want to know the proper way to lower the ph. should i wait until the moisture meter is showing low moisture and then water with a ph lower than 5 or 6 in order to try to offset the higher ph, or should i just water with a ph around 6 ?

this is the first time i have really payed attention to my soils ph and i have never adjusted it so any help would be great!

thanks in advance

Viniger...or does that raise it? i know baking soda raises it... so i think viniger lowers it... haha wait for another person to post tho xD... wow... what a waste of a post... sorry bud...

Vinegar or lemon juice will lower the PH........more acidic.
Baking soda or lime will raise the PH.........more basic.

Vinegar usually takes a couple drops per gallon.
Baking soda usually takes just a pinch or two.

well i have ph up and down that i can add when i water them. should i not just use that?

lol, well why arent you using that then... so yes... I see nothing wrong with using it.

to answer yiour question about lowering your water ph to offset the high soil ph yes u can do that i had to do the same thing

i just don't want to be an "over-waterer" and have problems with my seedlings from watering too much to try to constantly alter the ph in my soil. i didn't know how much it ph mattered with soil grows. i know i heard soil can buffer it or maybe not?

well my soil has been at like 7.5 for pretty much my entire grow so far and i havnt had any problems yet

ok, well my ph appears to be almost up to 8 this morning so i watered them good with watered with a ph of 5 today to see if that would help lower it. so far it hasnt helped at all though

many probe style meters aren't made for constant immersion in soil. Something about corrosion of the metals iirc. This steady incline of the readout may be accurate or misleading. Check your directions and see what the manufacturer reccomends. I know on mine, storing clean and dry, and lightly scouring with a "scotch brite" type scouring pad prior to use is suggested. Also, it specificaly mentions not leaving in soil for longer than one hour or damage to sensor probe may occur. For what it's worth.

whoa, just read the back of mine and it says clean tip after using... i just assumed they were supposed to stay in the soil constantly to avoid root damage... i just cleaned it and will check the ph later... if i haven't messed up the sensor already
