Ph problem with pics

[ShroomDr]

no, im conserned in gereral. The white spots are just a symptom. When i started this thread, i thought my PH fluctuations were over with. and wondered if that was the extent of the problem.

I came home 6 hours later, and see that the pH is rising again. it was stable the past two days. (I added the H2O2, the first time, 3 days ago.). But i am POSITIVE the rising pH is not good, and it is possible, the the high pH is locking out boron, copper, or whatever is causing the white spots.

I just want to fix the rising pH, i am growing dwc, so no dol lime.

measuring with a hanna 19829 combo meter. I calibrated it two days ago.


pH6.31

well, the lights will go off in about30-45 minutes, any more help would be appreciated.

I applied 35ml of H2O2 to 3.25Gal of water btw.

I edited the first post, but only to BOLD the pH, I have earlier data, but this is when i think the problem started.
Heres the earlier data

Whats you EC been doing this entire time? Has it been going down/up or has it stayed the same?

 

[Guest]

bah, had no idea this was hydro, forgive my slacking skillz

well its a boron def for sure... PH could contribute to it since it is fluxing like that but honestly I don't do hydro...and with no lime...I dont know where to go from here.

It looks like your pretty deep into the grow though... so it wont be too bad if it continues to get worse.. least not as bad as if you wer ejust getting it going... what day flower again?

sorry i am no help

my friend listen to what i say...up your nutes and your ph wont go up
in fact if to high it will go down..over 4 hr to 12 hr...ec...you can control ph with it and in fact in my humble opinion it is the art of dwc reading your pens...what the plants have ate...ppms go up they are consuming more water than nutes..ppms go down they are consuming more nutes than water...nute solution to hot ph will go down...nute solution not hot enough ph will go up...i personally use gh nute with the lucas formula...it really does not matter if your mix is rite(recipe)its most likely the ladies consumption...again...ppm's...ph = everthing you need to know

Ca162
Fe1.5
Mo 0.9
Cu 0.9
Here is where i get my calculations from.

actually, its 11/12th of that, because those are based on 3 gallons, and i add an extra .25G to top off(3/3.25 = 11/12).

That should eliminate the Cu.

Could they not have added Boron to the PureBlendProBloomSoil? (Ive seen the thread by sproutco.) I dont see B in my catalog with Liquid Karma, and its not listed on the Cal Mag Max.

Maybe i need to start adding some sweet back to the program. It does contain boron.

But Do you REALLY think i need to up my feeding regime? I never read where a lack of a micronute caused the pH to constantly rise
I will for sure add some sweet later, but the pH is the problem.

Ill keep reading...

Thanks for all the help so far...

i am telling you what i know from experience...listen to it or no...thats up to you...but if you follow what i say you will see

how long hydro my friend?

 

[ShroomDr]

hydro for 6 months. hydro is all i know, but i have a few extensive grow logs here at Icmag.


its not that i don't want to listen to you, its just i would like at least one more person saying the same thing.

hmm that's difficult, can you show us pics that show the actual colours? Maybe take one heavy affected leaf of?
I do see a little fert burn though

1vs1 and its not like the pH rising was gradual, it was an all the sudden thing.


The ppm was steady after topping off before this pH problem. If it would have been dropping, I would have added more nutes. I thought this is what 'watching your plants' was all about.


Im all ears (or eyes, in this instance), im just doubtful that a more nutes is better, im already over lucas on most.

 

[Guest]

do a test with one plant learn the way ph and ppms and consumption work...quit following advice and follow the pens...they tell all

You stated molybdenum and copper at .9 ppm...Do you mean .09? That sounds more right. This is very little. Your probably giving the plants too much phosphorus. You should be using sulfuric acid for your ph down so you don't overdose on the p. Your using more than 4:2:1 on the calcium. Too much calcium = boron def. Ph will affect your micros because they are probably not chelated. Iron may be chelated but I bet the others are sulfates. This is very sensitive to ph. Boron can not be chelated. I still am leaning toward copper problems but boron could be a possiblility with the new pictures. Get your fe, mn, zn, cu, b, and mo totals and we can be critical of the levels. Too much zn can cause a cu problem, etc...Mo should probably not equal cu like in your solution. I have heard this can cause a cu def. You might consider in the future making your own nute solution including micro levels. Manufacturers give you a generic level especially micros and are shy to raise levels of things.

I had a dream we were both on my computer and I was getting you the boron spray rate for your plants. I was giving everyone fried chicken.

that is all.

I understand the B or some micro is out of whack. But the pH rising almost 1/2 a point in one hour. I have never seen a reservoir act like mine that was healthy. And i thought too much P would cause a low pH, not a rising one.

I couldnt care less about the B or Cu, since i keep having to drop the pH every hour. It isnot possible for me to stay with my plants 24/7 and keep dosing them pH down.

Im sure all the pH down is not helping my P level either.

the lights come on in a few minutes, hopefully the H202 has stablized the pH.


I had a dream that i went o purchase a bottle of SM-90, and it was $50 a quart.

Fuck that dream.

.....I just don't understand why no one is chiming in on my CONTANTLY RISING PH, that has been basically uncontrolled, for 6 days now.

The only thing that settled it was the first aplication of H2O2.

Light on in 15min

Outta curiousity, what's your res temps and water source/ppm? Root rot can cause some funky PH issues as well as hard water buffering the PH...

 

[ShroomDr]

water temp is HIGH, 81.1F, im working on lowering it; but the cabinet right next to it has the same temp, and it has a stable pH.


We are having an abnormally warm Nov, and that is why the temp is high, i realize it should be 68-72, but if one DWC, is pH stable, and the other is not, the high temp is not the SOURCE of the problem. Both DWC's are above optimal temp.
