Not knocking on your nutrients, just I think it could be the culprit, esp in my exp thats roots shit fucks with the ph immensely, and organic in hydro... I smell your nutrients might be the problem, but I have no exp with the roots organic in hydro.. Have you seen anyone on this site use it in hydro??

thanks for the article! I do have friends that use organic nutes and have read up on it. i TOTALLY agree that i shouldve gone with non organic for the hydro. but unfortunately 3 weeks ago i dropped nearly 800$ on 5gal jugs!!!!! considering i do have a fairly large soil grow as well. I mean if things persist to get worse based upon the looks of the plants i will flush and and start with a new line of nutes (would that be safe?) I also think that cleanliness has a lot to do with it all. My soil res i go every 2 weeks NEVER had a problem. but with this hydro i am going to clean and swap it out every week no doubt.

as for res temp. DAMN water chillers are expensive! id buy one too if one could manage both res. but cant afford TWO right now lol. fortunately enough i have an ez cloner and in order to maintain the temp on the water in the ez cloner res i got a drop freezer and stocked it with 1gal,2gal, and 1 liter jugs =) i did just add a 1gal block into the res and didnt drop but a degree or two... i will keep on with the trial and error

Yes you can flush and change nutrients. I'd go and buy small bottle of florakleen, gen hydro's micro, grow, bloom, kool bloom and rapid start. GH's 3 part is so easy to use and is forgiving. That would be a good start for the less exp'd in hydro grower. It's what I have used for the past 2 years and has been a breeze. I'm sure there's better lines and different opinions but in my exp its pretty fail safe..

Actually. I see a problem right off the bat. Your trying to ph balance your entire system. Here is what I can share with you.

If you add concentrated nutrients without mixing them into water first, and then adding them to your rez, you'll have random PH fluctuations.

If you run a feed cycle, ex: nutes/water only/nutes/water only. Stop that. I was correcting my falling PH with water only. I constantly had PH changes until I started adding PH corrected water.

Today was the first day that I woke up and my PH wasn't bonkers. I have been consistently doing my PH changes by making up a new batch of nutes. If my rez says 5.6, I'll make a 4 gallon batch of tea at 5.9, and I'll watch it slowly raise after it cycles a couple times. My PPM's are much more stable too.

To start this, I pumped out 12 gallons of old mix, and mixed up 12 new gallons and put it in. Remember, salt deposits are part of that PPM. So the way I circulate, I will 4 gallons of used water out, and put 8 gallons back in (they are going through about 4 gallons per day on their own).

Course, my experience might not help with your setup, but I feel your PH pain, and I wanted to help anyway I can!!

i havent experimented with teas yet ....your method is interesting, i understand it but by taking away nutewater and then and adding new nute water arent you playing with the NPK ratio, i mean how are you calculating each element. im interested in your method just still trying to grasp it...maybe because im not familiar with teas. i know what they are but again have never used or made one
. thanks

H2O2 and Roots organic?? Um you might want to rethink your fertilizer, just saying its a waste to use organic. Just use synthetics if you are adding H2O2 to your rez water....you are killing all of the beneficial microbes with the h2o2 anyway

awesome, i just bought a gallon of florakleen yesterday i might as well pick it up , and fix the error before it potentially gets worse. How does your product turn out for harvest, im assuming nice!

like these =) =)

I do see a little brown there.....

 

[bongmarley7]

im going to get the 3 part gen hydroponics right now. My gut is telling me to, so should i empty the res today, flush with florakleen and water by itself right? do i run a 24 hour cycle with that? it will be 3X15minute cycles at 6 hours apart and then i would drain that water and fill it back up and then start the 3part......is that correct, if so, HOT DAMN i gotta a busy day ahead of me........cant wait for my supersoil to be finished uuuuhgggg lol

 

[Krondizzel]

Actually.. Your roots look in decent shape. If you can, the h202 will help you.

I run the 3 part flora series, gro, micro, bloom and also run grotek instagreen and general hydro calimagic.

Now, something to say about that, is the instructions on the back of the bottle, are for 1 bottle. Meaning, instead of 1tsp/gallon like they all recommend.. I have to 1/4 that because I use 5 bottles of shit. If you follow their directions exactly, you'll have a PPM through the roof!!! My first mix was for 2400.. I was like... the hell?!?! Well that was a huge waste of nutes. damnit.

As far as what 303 said, I agree, I run the 3 part series because I saw someone use it before and it was tried and true. So far is tried and true for me as well. General Hydroponics gear is legit.

Florakleen? I still have a quart unopened. Haven't needed it yet.

Yep exactly. Being a week into 12/12 I'd run "Late growth" on their chart diluted down by 20% or so, I have gotten some amazing results with rapid start, unfortunately its expensive, you can go without it. The floralicious plus you can skip as well, I have it but don't use it.. Good luck.

PASTED....



If you don’t know, there exists a site by the name of CannaStats that contains a wealth of thick, numerically-balanced information on efficient managing of the more important aspects of the indoor cannabis grower. The page in question today refers to the discovery of a nutrient profile for cannabis that is both very simple, and economical to maintain.
Here’s the direct link. http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htm
There’s a somewhat magical ratio in there, referring to the amount of General Hydroponics Flora Series fertilizers to use to sustain healthy, optimal cannabis growth indoors under HID lighting. The ratio is 7.5 (round up to 8 for ease) ml per gallon of GH FloraMicro, and 15ml per gallon of GH FloraBloom.
This ratio can also be described in shorthand as 0G-8M-15B, referring to the three-part system of the Flora Series, using 0 ml’s of FloraGro, 8ml’s of FloraMicro and 15ml of FloraBloom per gallon. Some people refer to this formula as the Lucas Formula, arrived to by someone on a cannabis forum of said name. Anyway, the name doesn’t matter, it’s the ratio that does.
That nice little ratio right there gives us these ballpark PPM figures. (These PPM figures represent elemental PPM values, which are different than those measured by TDS/EC)
100N-100P-200K-60Mg
In other words…

• 100 PPM Nitrogen
• 100 PPM Phosphorous
• 200 PPM Potassium
• 60 PPM Magnesium

Now I know that there are more elements than these that are needed to grow good bud, however, these numbers are the most important since they are needed in higher quantities than other mineral elements like Sulfer, Calcium, and the trace elements. Using a complete hydroponic mineral fertilizer like the Flora Series from General Hydroponics will contain all the mineral elements needed for optimal plant, and bud growth.

WOW that link is GREAT! thank you sooo much! So i know i said i was going to get the 3 part but i got the 2part A&B Aquaflakes by house gardens!

Florakleen? I still have a quart unopened. Haven't needed it yet.[/QUOTE]


I am going to use the florakleen because i started roots organics november 26th and need to flush everything out so i can start the Aquaflakes and go the clean chem route for this hydro setup!

 

[bongmarley7]

Alright guys! thanks for all the help! i finally finished EVERYTHING lol cleaned and detailed every bucket and more! am running Florakleen right now to start fresh tomorrow with Aquaflakes A&B . Current ppm is at 50, temp,70degrees, and ph 6.1!!

 

[Doer]

View attachment 2423063alright. novemeber 26th i mixed up my hydro nutes in a 55gal res.When the ebb flow ran the ppm was 630 and the ph was 5.2 so i added 50ml of PH up and it brought it to 5.6....in the morning i woke up and the ppm was at 590 and the ph was at 6.4, (I added 50ml of ph down and it brought it to 5. THIS MORNING i go in View attachment 2423062and the ppm is at 780 and ph was at 7.1!!!!! I added MORE ml of ph down and it brought the ph 6.7.....

I dont know why its fluctuating so much. I use all roots organic nutes and understand that may be why because theirs no way to measure the EXACT NPK of organic notes but should i just keep using PH down to stabalize the the res? am i using tooo much PH? or should i mix my nutes....

Well, I've run a computer track for months on my UC rig and there is nothing really stable about pH unless unless using buffered nutes. I'm using Dutch Masters finally and well worth it. Not organic.

The medium can contribute to pH rise. Rock wool is the worse. I buy clones in rockwool and I know what I'm in for that first week or so.

On my pH graph with GH nutes, unbuffered. The pH swings a full point on its own between light cycles. The plants do that. It is well documented in the literature, also.

Another thing was I had pH swings big time before I went to RO water.

So, if you are just stabilizing the res., just keep going until it is stable. I keep careful notes on what does what in my 70 liter pond. And I use the 13% Nitric acid and 13% Potassium Hydroxide, (rarely) 1/2 ml at a time. With 55 gals you will move to the cheap route soon enough.

Also good to mention, pH swing is desirable around 6.3 - 5.4. That will get some uptake of certain nutes that don't do so well at 5.8.
