This is a recent update to my post above.

As I mentioned, I have been trying to lower the PH by approximately .3 - .5 every 6 - 12 hrs or so, until I get to a steady 5.8 - 6.2.

When I sat down, and wrote my earlier post, I had just finished lowering the PH in my system using the method above, to about 6.4. This was at approximately 11:00 a.m.

I just checked again at 3:15, and it is once again is at around 7.0 - 7.4.

Why is PH raising so dramatically on a fairly even basis? And what could I do to lower it, and keep it stable?

I am here to help you, but I need more information.

Of course you already know, it is very normal for the pH fo flucuate as they eat the nutrients. Daily, I adjust mine, especially the first 3 or 4 weeks, then AFTER I remove the water pump (that harbors debris adn dead matter and trash) it stablizes for me.
I suggest no more than twice a day, once in morning, once in evening, adjust it to where you need it to be.

post # 13 starts talking about pH.

Did you soak the cubes all day in pH balanced water?

IF NOT, then make some 4.0 water, like a quart or gallon, and pour one ounce, like 4 tablespoons on each cube every two hours or so for a few days.

Tell me what week you are in, when you started, etc.

Hi Roseman,

I posted as much detailed information as I could here "http://www.rollitup.org/dwc-bubbleponics/261058-new-bubbleponic-grower-comments-advice.html" and in my grow journal. If you read that, it should give you a pretty detailed description of my set up and schedule so far.

I am going to try now, mixing 1 gallon or so of water, lowering the PH to 6.0 and pouring a once or so over my cubes, at 2 hr intervals.

I am also now going to adjust my PH again to aprox 6.4 or so.

Thanx for all the advice, and please follow my threads to keep updated.

To get the cubes pH RIGHT, soak it in 4.0 water . The 4.0 water brings a 8.0 pH cube to closer to 6.0 .

PH: 7.6
Temp: 80 F
Hum: 47

LSD: 1 1/4 "
AK-48: 1/2 "

As per Roseman's advice, I now am going to mix a gallon or so of 6.0 water, and pout about a ounce or so over my Rockwool cubes every 2 hrs or so. Hopefully this will help lower my fluctuating PH and help to keep my reservoir a bit more stable.

I was also thinking about putting some ice cubes in my reservoir to help cool the water down a bit. When I put my hand in to check the water, it was very warm.

I'm also wondering exactly how I should go about giving nutes to my babies. Saturday and Sunday I mixed 1/4 of my Grow Nutes, and Micro Nutes, strained them through a coffee strainer to remove all small particles, and then added that gallon to my tank.

I have included updated pics to show how far along my babies are now.



Oct. 26 6:30 p.m

PH: 6.0
Temp: 84 F
Hum: 50

I just recently finished draining out 1 gallon of water from the reservoir, and adding back in 1 gallon of 6.0 PH water. When I checked it, it was again close to 7.2. So lowering it by approximately 1.2 is quite a bit, but since I only added 1 gallon of 6.0 water to 5 gallons of 7.2 water I am hoping it balances out. I will also be watching my plants very closely, and at any sign of curling or yellowing leaves, I plan to re drain and refill using 6 gallons of 6.4 water.

However, now when I am testing my reservoir PH (with the 1 gallon added) it's reading 6.0

I also added in my 1/4 pack of grow and micro nutes at this time. (mixed and strained in aprox 950 ml of water, and strained.

It should also be mentioned, that earlier today I filled up a water bottle with tap water (7.0 - 7.2) and lowered it down to 6.0 and pouring a ounce or so over each rock wool cube, at 2 - 3 hour intervals to help and lower the PH of them.

I know I am probably asking retarded questions, but I'm just trying to be as active and efficient as I can, being as this is my first time.

As always comments and feedback are appreciated.

I said 4.0

"Did you soak the cubes all day in pH balanced water?

Rose,

I already mentioned that I forgot to soak my cubes before I put them in. I only soaked the 4 that now hold the clones, and they were soaked in 7.0 water. And currently the lowest my PH meter will go is 6.0

What I will do though, is use my crappy PH strips because at least they go down to 4.

I will try this today and keep you guys updated.

Thanx again

Today I decided to make a few major adjustments. After having constant fluxuations keeping my PH down, I went and bought some R/O water, 2 X 5 gallons. Then I emptied my system and replaced it with 5 gallons of the R/O water. The last Gallon, I mixed in exactly 1/4 of a Grow Pack and 1/4 of a Micro Pack and then added that giving me 6 gallons.

The SH guy told me apparently a lot of people having been having issues with High PH and the R/O water almost always fixed there issue. I have also been pouring 1 ounce of 4.0 water over my cubes every 3 hours, in hopes of lowering their PH. I'm kinda try the R/O Water, I've heard mixed reviews but I guess we will find out...

I also decided to add a 2nd 12 " air stone to my tank and attach it using a coupler to my air pump. And I added a Duel Spectrum flowering light bulb, so now I am running 1 flowering 1 vegging.They are hanging side my side aprox. 10 " from my plants.

LSD is starting to get a yellowish streak running down it's center 4 leafs, I have included a updated pic. And AK just started growing it's other fan leafs but not getting much taller. I promise myself, if my babies make it threw and stabilize I'm going to smoke a big one in their honor, and relax.

You're doing good, and ont he right track.

Don't let that discoloration bother you for now, they will be fine.

PH: 6.4
Temp: 86 F
Hum: 45
Wat. Temp: 90 F

LSD: 1 3/4 " (8 or so fan leafs, have shown themselves but are still showing signs of discoloration)
AK: 1" (now has 4 or so fan leafs, still the runt)

Notes:

- The PH still seems to be raising slightly, but I assume that's because of the still high PH of my Rockwool cubes. I was wondering if I should still be pouring a ounce or so of 4.0 water over my cubes. now that I have switched to R/O water. Advice?

- I don't plan on adding any more nutes, at least for a few days. Depending on how my babies adapt to all the changes. I will probably add 1/4 pack or so on Saturday.

- Now that I have switched to the R/O I don't plan on playing with the PH at all, regardless of it's little spikes. If there are any drastic changes, I will address them as they come up.

- With the additon of that flowering light, my room temperatures have risen quite a bit. Therefore, I have been keeping my roll up door, fully open and closing my closet door. This has been keeping my room alot cooler (closer to the 75 - 85 F range) but I had to turn the flowering light off last night, and just run the vegging one, so I could sleep in the same room. Later on today, me and my room mate are probably either going to install a small Bathroom sized venting fan up top, or 2 computer sized fans at the top of my roll up door way. Opinions and advice on the best way to keep my room vented, and temperatures down are always appreciated.

- Also, if you can see in the full view pics, my clones seem to be wilting quite a bit. I just pulled them out of the cubes 1 by 1 and still havent noticed even the smallest of root growth. Prob gonna try Petrol420's guide on cloning on Saturday to see if I can establish some good clones.
