Hey all, I know that my GH 3 part drops the pH of my water, I want to know about your nutes. Could you please tell me what line you use and if they drop, raise or have no effect on your pH, trying to compile a list. Thanks.
Do your nutes drop your pH?

Maxibloom drops my ph.

Yeah my Fox Farm nutes do the same thing. Specifically the tiger bloom, and grow big take CHUNKS out of my Ph. like a 3 full point drop almost. 4+ when I use them both!!
thanks guys, it helps a lot.
Well, an "expert" at another site got in my face for trying to tell people that nutes drop pH, I can speak for my nutes but I wanted first hand experience even though I more or less believed it was the case.
lol, don't even get me started on R/O water. Ever try to tell a person that their problems are because they are using R/O water instead of their perfectly good tap water? Oh man do people go ape shit.

my veg and bloom nutes drop my pH, but i hear Rhizotonic raises it.

Hey I run a recirc DFWC. I mix nutes then ph up to 6.0 mine feed hard so I ph up and top off everyother day or so. I reccomend a flush every few weeks too.
I don't know if this will work with your nutes, but it does with mine. If you adjust your water's pH before adding the nutes you'll end up using less pH up or down. I don't bother doing it anymore because I'm small time, but back when I had an op it did save me many trips to the hydro store for product.
Example: I wanted my nutes at 5.5 so I adjusted the water to 6.0 and then added the nutes and it would drop the rest of the way. Obviously you have to do the math.

I find Rhizo raises pH but I think thats probably the only product of maybe 6 or 7 that I use that does this... well spotted
General organics drops me from 7 down to 4.9-5.2. They say not to PH it but I had problems. I raise the ph to about 6.4 and feed. Plants love it.

Yes, but why?
for the o.p. of the thread and anyone else:
learn
Alkalinity refers to the capability of water to neutralize acid. This is really an expression of buffering capacity. A buffer is a solution to which an acid can be added without changing the concentration of available H+ ions (without changing the pH) appreciably. It essentially absorbs the excess H+ ions and protects the water body from fluctuations in pH. The presence of calcium carbonate or other compounds such as magnesium carbonate contribute carbonate ions to the buffering system. Alkalinity is often related to hardness because the main source of alkalinity is usually from carbonate rocks (limestone) which are mostly CaCO3. If CaCO3 actually accounts for most of the alkalinity, hardness in CaCO3 is equal to alkalinity. Since hard water contains metal carbonates (mostly CaCO3) it is high in alkalinity. Conversely, unless carbonate is associated with sodium or potassium which don't contribute to hardness, soft water usually has low alkalinity and little buffering capacity. So, generally, soft water is much more susceptible to fluctuations in pH from acid rains or acid contamination.
Methodology: Alkalinity is an electrometric measurement which is performed by the computer aided titrimeter (CAT) and the pH electrode. A potentiometric titration is taken to an end-point reading of pH 4.5. The amount of acid required to reach a pH of 4.5 is expressed in milliliters. The calcium ions (CO3) neutralize the acid in this reaction, and show the buffering capacity of the sample. From the amount of acid used, a calculation will indicate the amount of carbonate (CO3) involved in the reaction. This then is expressed as mg of CaCO3/L even though actually part of the alkalinity may be contributed by MgCO3 , Na2CO3 or K2CO3.
Ya, Fox Farm is real bad about dropping the ph...tiger bloom drops my ph 7 water to 4. Nothing like some ph up to fix it

I know it was mentioned earlier but silicate blast will raise ph. I love this stuff. I only use it in veg and first half of flower. I use ph up for 2nd half of flower cause the silicate is chem based nute not organic (needs good flushing).

Yep ,
Good ole Buffers .
All nutes I've used yet drop ph in an attempt to get you in the ballpark of being proper for your given grow style . Hydro , soil , soiless etc...
G/H 3 part , Maxibloom , FNB so far here .
Wish Dongle 69 was still around , she'd have killer input on this I'd bet .

Almost anything you add to water in teh form of nutes will drop yer pH.
