Ph questions

Hello growmies,

I’m wondering how my ph is getting so low on some of my plants i thought it could have been from over feeding and nutrient lockout. I have 1 plant that has a ph of 5.0 and is in week 4 and has only had 1 feeding of nutes so far. So how is the ph drop to 5 when i put it in at 6.3 yesterday. Is it the ph up and down soloutuon disapating and leaving the ph left of the water plus nutes? If that’s the case should i maybe you a smaller amount of water. Is it fine? That plant shows not one sign of stress. Then i have another 2 plants in late flower on week 10 with a ph of 4.9 and the lower leaves are more yellow green as you would expect with ph issues. Any insight is welcome.

When you say you are growing in coco are you talking pre sifted and buffered coco or some plain old rehydrated block coco? Was your coco buffered? If not your your pH will be all over the place. As far as yellow leaves at week 10 that is normal as you stop feeding and she starts eating herself to feed her flowers. At week 10 of flower she should be very close to harvest if not already past peak period. Pictures please.

All of this right here, and TBH most new hybrid strains are done at week nine, some even at 8, if you push them too far after that very good possibility of hermaphroditing.

Hi @greenbtree

@mayakid, makes a valid point about the buffering, but its something you should look into due to the fluctuations in your pH. Best to test your source water, and your runoff water to get a better idea whats happening.

to be honest - never checked PH - always had great plants and yields --try to keep it simple and don’t go down the “rabbit hole”

That would be just great luck @HawkMan . Ph is incredibly important. When you go to the doctor that the very first test they do on you.

The human body maintains a very narrow pH range, typically between 7.35 and 7.45. Any deviation from this range, either towards acidity (acidosis) or alkalinity (alkalosis), can have serious health consequences.

A slight drop in pH (towards acidosis) can lead to seizures, heart arrhythmia, and even coma. A slight increase (towards alkalosis) can also cause issues.

With understanding the plants, comes better understanding of the human body as well. It is a beautiful similarity.

Most plants thrive within a pH range of approximately 6.0 to 7.0. While this is the ideal range for nutrient availability, many plants can tolerate and even thrive outside this range. For example, blueberries, azaleas, and rhododendrons prefer acidic soils with a pH between 4.5 and 5.5. Conversely, some plants like roses prefer neutral pH, around 6.5 to 7.0.

Cannabis, like many plants, prefers slightly acidic soil conditions. It tolerates a wide pH range (5.0-7.0) without symptoms of bronzing or interveinal chlorosis (yellowing of top leaves), but pH levels outside of the optimal range of 5.8 – 6.2 will limit growth

I do understand - Guess grows would be “better” if I PH-ed them) understand - thanks for the info – old saying “can lead a horse to water” or something like that. Do have PH equipment and even use PH perfect nutrients by advance Nut

So i noticed that when I’m feeding them sometimes the ph will start to drop from when I’m pouring it in ie water going in at 6.0 first but of run off 5.9 then proceeds to slowly drop is it because it’s buffered ? Or what is the reason for this usually… i check the ph of the water before feeding the runoff and i check with soil tester it always is low then climbs as it dries as expected . Just sometimes 1 or 2 plants will start to go down right away i figure if it’s low and dry that’s probably too much nutes but can’t figure out why it does it at first… i got all my plants within range after flushing them and I’m having far less problems with my feeding now. But I’m just curious.

When using AN pH perfect products I have found them to be very accurate and no need to pH. The waterings between feeding have always needed to be adjusted. When I first started growing I didn’t pH. When I found out the importance I started pHing and my plants stayed healthier and my yields increased.

So its losing oxygen and hydrogen molecules.

Various chemical reactions can produce or consume H+ and OH- ions, thereby affecting pH. For example, photosynthesis and respiration in aquatic environments can influence pH levels.

I took a bowl, filled it with my nutes and a straw to blow bubbles in it. After seconds of blowing in it, i watched the ph jump.

It was really cool to see and understand that.

My Dr has NEVER checked the PH of my body. They have done a bazillion tests, but never PH. You know I always wondered about that too. Because I knew about the fact that with Ph that is off it can cause a lot of problems. I think I will talk to my Dr. about that and get it done.

If organic i dont believe u need to ph the nutea but soil coco and hydronit is an important step as plants uptake nutrients in certain ph ranges in coco its between 5.5 and 6.4 5.8 and 6.2 being the sqeet spots. Soild is like 6.2 to sometimes a 7 but 6.8 being a sweet spot like coco vegges better in the 5.8 range and in glower they uptake nutes better in the 6.1 6.2 range i always check my ph but rarely ever check pph or ec only if i see issues arise will i chase all yhem numbers. Lol. I wont even do ph run off unless i see an issue arise that i believe might be a ph issue.

Lmao. I dont think mine checks mine either. And we basically do as a plant does but in diff ways. I think im lacking silica as mu joint hurt me anymore. Not strong enough to jold the weight. Lmao

He doesnt have you pee in a cup? Ph would be one of the pee tests they do after taking that sample.

Oh yeah lots of pee in a cup episodes lol….just never listed PH. Just got one a month ago for kidney tests no ph listed.

And
D it’s a she lol

Doctors often test urine pH. It’s a routine part of a urinalysis, which can be used to assess various aspects of health, including kidney function, metabolic conditions, and the risk of kidney stones. The urine pH test helps determine the acidity or alkalinity of urine, providing insights into a patient’s overall health.

Here’s why doctors test urine pH:

Assessing Kidney Health:
Urine pH can indicate kidney function and the potential for kidney stone formation, as different types of stones may form based on urine acidity.

Diagnosing Metabolic Conditions:
Urine pH, along with other tests, helps diagnose systemic acid-base disorders, which can be related to metabolic imbalances.

Monitoring Treatment:
Doctors use urine pH to determine the effectiveness of certain medications, especially those used to treat urinary tract infections (UTIs), as some medications are more effective at specific pH levels.

Detecting UTIs:
A high urine pH can be a sign of a UTI, and monitoring pH can help guide treatment.
Investigating Other Conditions:
Urine pH can be part of a broader urinalysis, which can help diagnose a variety of conditions, including kidney disease and other underlying health issues, according to Centers Urgent Care.

The urine pH test is typically performed using a dipstick that changes color to indicate the pH level. The normal range for urine pH is generally between 4.5 and 8.0, though ranges may vary slightly between laboratories.

Women usually have more ph conversations than men do.
