5.2 ph water for 7.5 ph soil?

is this correct ph adjustment or should i always be using between 6.0-6.5 water?

6.5 no higher than 7

can i get a second opinion?

Why do you think this is a correct adjustment, it makes no sense.

First how did you measure your pH?

If that really is your pH, you just want to water with a pH of 6.5 to 7.

There's some leeway there but too high or too low pH will lockout nutrients.

When that happens you flush the soil with correctly pH'd water and this will correct your problem.

Throw some finely granulated dolomite lime into your soil, then your ph will be dead on throughout your grow no matter what ph your water is..

Simple as that

in one of SeeMoreBuds' books he says the optimum ph level for soil grows is between 5.9 and 6.0. to begin with the soil they had was 5.1 ph so they used 7.4 ph water. the graph shown with it only goes from 5.1 to 6.1 with 6.1 ph soil using 6.4 ph water. just seems that the opposite would also be true for soil with a ph of 7.5. i like the idea of dolomite lime, but my water comes out at around 9 ph usually. i'll consider the idea though, thx. PH readings taken by electrode ph meter.

I dont think you understand ck. If you use the lime, it doesnt matter what your waters ph is. soil will always going to be 7

good to know. wasn't sure if 9ph was too extreme. dolomite lime it is then. will be a nice contribution to my laziness =] thx for your help guys.

if you are using water w/ ph of 5.2 to bring your soil down to 7.5, your soil is way way too basic in the first place.

dry soil was 7.5 water was 5.2. i figured that would bring the average of the soil/water to about 6.3. if that's not logical then can someone tell me what i'm missing? . Sucks for SeeMoreBuds too because no one on here agrees with anything that came out of that book lol.
Taken from the end of the book "SeeMoreBuds can often be seen playing frisbee on Santa Barbara, California beaches and hanging out on the
message boards at www.rollitup.org." funny he's esteemed by ed rosenthal yet the community he supports doesn't. maybe someone can send him this way to resolve the confusion. i'm sure i'm not the only one who read that book that made that assumption.

I am superNUBE, so please forgive my ignorance, but please explain how the lime perfectly adjusts the ph of the water and the soil. And how do you measure the ph of the soil?

Thank you.

dolomite lime has a neutral ph (7.0). if used in the correct proportions it will stabilize soil ph to near 7.0. apparentally damn well too if these guys are recommending to use my 9 ph water =] also i got my ph tester for under $30 at my local hydro shop.

checked the ph again today and it's down to 6.6. haven't used higher than 6.0ph water for the past few waterings. watered with 6.4 ph water today.

been using apple cider vinegar for the past few waterings also which obviously holds it's acidity much better than the normal stuff. thx to an old hippy grower =]

i water my plants with 7.3 water with a runoff with around 6.7...

The lime is a good idea, i use it myself. But, whether you use the lime or not, you still need to adjust everything to about 6.5 before pouring it in. Since your PH is a little high, it wouldn't hurt to water/feed with stuff PHed to around 6.0-6.2, but i wouldn't go any lower than that.

7.5 to 5.2 is a big jump in PH, and would likely shock the plant, so i'd recommend against it.

the thing is that on the next page it says you should usually use between 6.0 and 6.5 but since the ph of the soil was so low to start out with, they used 7.4ph water for the first few waterings.
so i'm thinking the science behind your statement to not go any lower than 6.0-6.2 would be because 7.4 is only 0.4 into the alkaline category but 5.2 is 1.8 into the acid category. sounds good to me, anyone else agree?
