PH lockout question

[false]

when you have a plant in soil thats been overwatered with low ph water causing yellowing , is it ok to flush and start feeding with a ph adjusted solution or should they be transplanted into new soil ?

it depends how old they are but i would try 2 get the ph up without transplanting....and what do you call low ph?

thanks for the reply Core , ph varies from 3-5. i have some moms about 15 weeks , and some teens 5-7 weeks and some babies 3-4 weeks old .

False, soil is not exactly like hydro... the water's pH that you put in may not be affected in the root zone, or it might...

Ex: Soil that has a pH of 6.5 (with dolomite lime)... you can water this with water pH'ed at 4.00, 7.00, etc...and believe it or not, in the actual root zone, the pH will REMAIN 6.5.

The goal here is to get the soil's pH dead on, not the water you're putting in it. If you suspect a pH issue then I'd highly recommend following the standard soil mix of 2tbspn of dolomite lime per gallon of soil. If ya dont you'll be playing the pH sliding game for the remainder of your grow.

Thanks Klutter , thats good to know . But ive been using two tblspns of dolomite per gallon of soil and still getting major ph issues . im trying to use earth juice organic ferts and didnt realize how acidic they were ,(shouldave been monitoring my ph levels )

What??

Klutter, are you saying that if you water perfectly balanced soil with 4 ph water it's going to come out of the pot at 6.5, therby proving this rootzone theory?

Hey False, good luck on your grow!!

I've only been a soil man, and if my water gets outside a 5.5 to 6.5 range they begin to suffer. The few times I accidently doused them with a 4 or a 7, they suffered much more.

The soil, well prepared and treated with lime, will DEFINATELY help buffer water ph issues, but you won't be growing at optimal.

I agree with Klutter, the soil is of prime importance, but if you really want to nail this you gotta spring for a good ph tester, and test the water after you've done your chemistry. Your plants will love you for it!!

I'm sure Klutter would agree with this formula:

Great soil, (it's amazing how many people don't know about the lime), PH balanced well + Great nutes and ph'ed water = Kick ass plants!!

Peace

kanibush: that's called buffer capacity, your system(soil) is stable enough to "eat" those ions that are out of the balance when u water

by adding lime you raise b.c.

that's why you have to add a lot of ph- or + sometimes, because ur buffer capacity is high, when you need to add just a little, your b.capacity is low

that's it

thanks everybody , im gonna get a digital tester today.
