Pure Blend Pro Question

[cocktail frank]

im guessing 100ml for the res? and not per gallon?
pbp drops my ph a good point or so, but never down to 3

now that i think of it, tap was 7.0-7.5 ph.
after bout 15ml/g pbp, 10ml/g lk and 5ml/g calmag+
ph would be under/about 5
so i guess i could say my drop was bout = to yours.
being you have a lower starting ph.
nothing silica can't raise tho.
or you could run an airstone in the res, that will rasie your ph for sure w/ pbp

I noticed the same exact thing at 10-15mls/ gal. For a while i just used some ph up. Then i started testing the runoff PH and watering with 5.8ish ph hoping the medium settled at 6.3ish. The runoff PH was really high. PH had risen drastically in the soil. Im convinced a res of PBP only rises in PH everyday. I quit even adjusting the PH on feed res and am having no more issues, although i will switch nutes after this round because of that and they have changed the ratio a few times on the label in the past year which cant be a good sign.

the values have changed because they used to have a soil and hydro formula, now its all in one

Wow...this has become a very informative thread! Love it.

To address some issues:

you cant accurately gauge RO water's pH. There is just not enough dissolved solids to get an accurate reading.

In all my discussion about this issue, this is the first I've heard of this. Again, very informative.

As far as Hydroplex goes, I still had some of the old formula left. Went and bought this one specifically for this formula.

It's 0-10-6

if you are absolutely sure it is the hydroplex that is causing your pH drop, use some common sense and stop using it.

That's good common sense. However unlike the past two cycles, I have had 0 problems with this grow....save for the PH drop when using Hydroplex. Which really isn't a problem, just a concern. My plants look the best they ever have, so MY common sense (which may be wrong) says "keep doing what you're doing!"(ya I hear my common sense out loud like the lol).
I too am in the

However, my plants do love PBP. Theyre super healthy.

boat.

Fifth, stop using 'ppms'. No one knows which ppm 'scale' you use. 'ppm' meters do not measure parts per million, they measure electrical conductivity (ec). The meter then use a (superfluous) conversion to something it labels 'ppm', but again this has nothing to do with elemental parts per million.

Again...in all the previous discussions I've had on this subject, no one has pointed that out, so this is the first I've heard of this. More homework for me to do. I thought PPM was PPM and was unaware of different conversions for this. I will give specifics, as you asked, down below.
I'll check out your sig Shroom Dr. and school myself on more of this.

and for the users of hydroplex, do you still have an old bottle with the old label?

No, I'm using the new one: 0-10-6. Only because between cal/mag and ProBloom, there's enough N, so I wanted a bloom enhancer that had none. The only reason I know there's enough N is because my plants tell me so.

Onto specifics. I will cover what I do to obtain a 500PPM mix. 500 is what I mixed to the last week or so, so it's my most recent results. Now I know that PPM are somewhat erroneous, but it's what I've been going by, so for the sake of consistency, I'll stick with that for now.:

Using this Watts Zero Waste RO system:

I secure 3 gallons of water.


Then I mix 150ppmm of this (roughly 1tsp):

Then 150ppm of this (roughly 1.5tsp):

Then +/- 150ppm of this (1.5 to 2 tsp), or whatever it takes to get to 500.

Then I measure it with this: The Hanna HI 98129 meter.

This is how I come up with my results of a PH in the low 3's

Any more input would be great.

@Carl....I'm going to go over you PH thread you started about the importance of PH in coco to shed some light on whether or not this is really and issue to be concerned about. I've read it before, but I think this warrants another reading or two.


Looks like I have a lot of research to do in the off season.

Thanks again everyone!

 

[mr noodles]

long time botanicare user here , it drop the ph to 5.5 -5.8 but not to 3....

i also complained a few time by the ph mood swing of the pbp soil formula for a while , i also complain on the multiples formula change botanicare went in the last years . they water down the pbp and release many fucking additives .


get a blue lab ec meter !

Perfect. Thanks. I knew I wasn't alone.

Im using the same , minus the cal/mag. I also get drops to low 4 upper 3's when doing a heavy flower dose. I been using earth juice ph up. Buds are hard as a rock and ginormous . Some minor issues last few weeks of flowering , but thats just me getting used to these nutes and new genes .

I currently have a DWC bucket with Botanicare as the nutes. I normally grow in soil, but want to try it all, so small experiments here and there are the way.

Last time I used Fox Farm in the 5 gallon DWC. No good. I love it in soil, but IMO, it ain't for hydro.


Anywho, this time around.....using PBP Grow, PBP Hydro Bloom, CalMag (as needed), Liquid Karma and the new Hydroplex.

In veg, this was the mix....... (oh, BTW, I am on well water....6.0 @ 70 ppm.

The bucket was filled once a week with fresh nutes and topped off with plain water in between feeds.

4 gallons plain water + 4 tsp PBP Gro + 1 tsp CalMag + 4 tsp Liquid Karma.....then ph'd to 5.8. Normal EC for this is about 1.0

Now that I am in bloom.......

4 gallons water + 1 tsp PBP Gro + 4 tsp PBP Hydro Bloom + 2 tsp Hydroplex......ph'd to 5.8-6.0

I am having VERY good luck with this formula. The sched and bottle rec's are VERY high IMO. Also, when running DWC, you can run a much lower PPM than other hydro systems.

I am at week 4 bloom with this DWC run and loving it. But I like soil better. LOL

I do not notice ph fluct nearly as bad as with Fox Farm.

Remember, all water is different as far as what is in it. The composition of the water will play a role in ph correction. Possibly making it easier or harder to correct regardless of what type of nutes are used.

JMO and 2 grams worth.

My water comes out near 9 for a PH and 115 on the PPM...when adding the PBP nutes it will lower the PH to 6.5...or there abouts...ya really wanna see some nutes drop the PH, go get yer self some Earth Juice and drop it in...the bloom lowered my PH to 4.5 and the grow was lower then that...
