need help lowering pH

nicklebag05 · 11-11-2010, 06:20 PM

2 of my girls are at a pH level of 11! all i can find is how to raise pH and nothng to lower it... ive been told white vinager? can anyone help me out? thanks

here are a few pics... plants bottom fans are perfectly fine then everything just turns all skinny and sharp blades- plant is very stiff other that leaves basically healthy for most part.

Add a weak solution of vinegar (acetic acid) to help lower pH.

Are you sure? How did you measure pH?

SmokeaJoint · 11-12-2010, 01:57 AM

In hindsight, yeah. 11 is closing in on being as caustic as lye. The ladies look pretty great for being chemically burned.

**mothernature** · 11-12-2010, 02:26 AM

I'm curious as to how the PH got to 11 in the first place?

**Pharm Girl** · 11-12-2010, 03:39 AM

what kind of medium are you growing in???

im using soil. hydrion paper to check pH. i tested it again and had someone else compare the color and its not quit at 11 more like 9 to 10. I think it happen cause i was to cheap to go buy water so i just filled up a bunch of jugs and where i live we have hard water, it seemed to happen after a few waterings of the house water but didnt think anything of it cause the water sat for at least a week... but i actually dont know how they got that high. all the other plants were fine. just sexed and only one good plant was a female and i have 2 for the skinny ones. they do look healthy but plants are stiff and leaves are sharp and feel brittle. heres more pics and some of the healthy one

I have to assume your readings are flawed or your paper isn't accurate. A pH that imbalanced should lock out most nutrients from the plant, especially one that high. If you leave water out, uncovered, it absorbs H ions from the surrounding air. Too long, and pH WILL be affected, but not to that degree that I've ever seen. How long do you suppose the ladies have been dealing with that high of pH? I'd expect to see negative effects from that sort of imbalance within 3 days to a week.

more then a week thats for sure... maybe 2 at the most. so if its not a high pH thats causing these tight skinny leaves- what could it be? even the new small leaves are tinner then grass(like lawn grass leaves) and very very hard. you cant even bend the main stem its as hard as a dam pencil. i gave them a 20-20-20 fert about 3 weeks ago and they responded very nice to that and it seemed when i started adding house water they went down hill... my house water leaves terrible film on my dishes and shit- could the calcium(i think thats what the film is) have anything to do with it? but all 6 plants got same water and only 2 were affected? thanks

When diagnosing deficiencies, Ive found this link most helpful.

The availability of boron, copper, and zinc is also limited at high pH and may cause deficiency symptoms on plants grown on alkaline soils.

Keep this in mind, because a pH problem also looks alot like a nutrient deficiency. It very well may be a pH problem, but geez the readings are so high its hard to just out n say "Yeah thats the issue".

You mentioned hard water. Its usually full of Ca, Mg, Sulfates, and Bicarbonates. And its always basic. Try the vinegar solution, but realize it takes a few days for results of the correction to manifest. The plants look decently healthy, color wise anyways. Correct for high pH, test for a few days, correct some more until your pH is around the range of 6.5-7.5. And perhaps consider investing in an electronic pH meter for accuracy?

I'm not sure why only 2 plants would appear affected if you're doing the same things on each.

farmergiles · 11-13-2010, 03:16 AM

The skinny leaves are due to the plants' expression of their genetics or phenotype.

The ones that have fatter leaves are more indica. The ones with the skinny leaves are more sativa. This is natural.

Your pH test is not giving the correct results- we can tell because if the pH of the soil or water was 11 the plants would die. They would look a lot worse than they do if the pH was 9.
So either there is some error in your method or the pH test you are using isn't designed to work in the way that you are using it.
So be careful adjusting the pH- you don't know what it is yet.

Could you describe exactly how you are checking the pH with the hydrion paper? That's like litmus paper, right?

You mention lots of tiny leaves and the stems hardening. Is this the plant changing the way it grows as it starts to flower? What lighting schedule are they on? Have you induced flowering?
Have you noticed any other changes in the way they grow recently?

**mothernature** · 11-13-2010, 05:05 AM

hmmm....

What kind of soil are you using and where did you get it (yard, garden, store?)? Do you have pets?

And, have you checked the PH of the house water? What is it?

nicklebag05 · 11-21-2010, 10:15 AM

im using just plain bag soil with no added fert. I didnt even give any nuits or fert til after they cam outa the phototron and under MH for at least 2 weeks. my house water pH is between 8 and 9 on the paper strip. i just bought a digi reader so ill check it out when i get back.
i gave the 2 a dose of vinegar last Monday and it seemed to help very nicely. then hit them all with sum Beastie Bloomz yesterday... i also noticed i started to have to purple stems?
They are like 3 1/2 weeks in to 12/12 and loooking great.
i was stealing internet from someone and got booted off so ill try to get some new pics sometime this week of the new and improved girls.
thanks for the help

SmokeaJoint · 11-21-2010, 11:32 PM

I've had plants with pink and purple stems with no problems. I think sometimes its just the plant.

nicklebag05 · 12-05-2010, 05:45 PM

alright here ya go.. some fresh pics at about 5-6 weeks into flowering. the couple that were having problems came out of it very nice. the beastie blooms is doing awesome. dont have a very good camera just a cell phone but can definitely see how good they are doing
