Ok to start with I don't have the best ph testing equipment...im using a milwaulkee ph tester that I always have to stick in the calibration liquid before I test, and I also have a walmart brand ph chemical test and it basically always comes up the same thingmy chemical ph probe tester says my ph is like 7.5 and my chemical tester says its 6.0 or lower, I trust my digital tester more than anything but I just don't knowI know my plants are all being affected they are about 2 weeks old and have a UGLY new growth defiency, all the new growth is like a dirt color, like brownish black, and the leafs are curling upI never imagined id have this type of prob at all im using RO/ DI water and I am now using a compost tea to water and in my bubble buckets to try to keep things under control but my ph meter is saying that my compost is still 7.4 and that's after I soaked some wood in it for a while im pretty much stumpedare my plants gonna dieI will post pics tomorrowI need help I don't want my plants to die, im growing white widow, and AK-48 they started good but I was unaware I was suspose to check ph to start with, cause my last grow I did without cheking for itthanks in advance

Your flying blind, but not as much as the people in this thread that are trying to help you.

heres my 2cents.

1. try and replace that digital ph pen with something you know will work.
2. get backup litmus paper strips. they're better than the drops imo.

Your plants will die indeed unless this ph problem is fixed. Get your ph fixed and everything else will fall into place.

I would stop useing the compost tea also. If I were you, I would flush my system and refill with RO + base nutes.

make sure u use fresh/good calibration solution... also dont contaminate the calibration solution bottle..

Thanks, believe me there is nothing i would love more than to go out and get a ph pen today but no one sells digital ones at all, so im stuck with my OLD milwaulkee one,lol so i plan to go out to walmart or somewhere today and get a jug of distilled water, and test it out and if its ph balanced im gonna flush my plants with it, the ones in soil, and the bubble buckets

its my only option today, thanks for the help god i hope this works

i may even but some ro water from my local department store and test it and see what it comes up as

sorry if i confused any one

yea i think its ok seeing as my reading always goes to what it is suspose to be, but thanks for the advice

have u had any probs with your calibration liq gwetting contaminated before, i dont think mine is but it could be

i looked in it yesterday and it looked pretty clear!!!!

i use a milwaulkee ph also... i've never had any problems with it.

maybe youre adjusting your PH to aggressively? how often are you adjusting? you could try less PH down more often.

blind blind blind. First thing determine wether your meter works correctly. This means using something else like ph paper.. First determine if it is indeed correct. Once you figure this out the solutions will follow.

Yes, thanks i did clean out my buckets tonight ( thouroughly ) I did have to BLINDLY add a small amount of vinegar to my BBs after feeling them back up, ive herd different opinions on whether or not u should add vinegar to a hydro set up but i trust the info i came across to be correct

Like i said tho i had to add a small amount per gallon to my BBs, and just wait

i had a digital meter to start with and it started going crazy today, just when ireally needed it

Im wondering tho, a good ph for soil, (organic) is like 6.2 to 7.0 correct, and a good hydro ph is like 5.8 to like 6.2 but i can go as low as 5.5 for hydro tho for error correct???

well my ph was last reading before it went coco for coa coa puffs that i had a wter ph of like 7.5 to 7.8 and when i added vinegar it took it down to like 6.5 to 6.3, i really hope this works guys i really dont wanna loose my freaking CROP...

thanks everyone for your help, please continue, im almost there, i dont know when i can get a digital ph meter

i ordered a ph chemical test online last night for like 6 bucks, its a general hydro color test

hopefully those will be good

thanks guys!!!!

Vinegar is a bad ph down due to its instability. Acetic acid (vinegar) Is not suitable as a ph down. Get your hands on some nitric acid or phosphoric acid.

Do not use vinager unless it's a VERY temporary solution(as in you ran out of PH down) . Start with a good base nute, GH or fox farm, go from there.
 
Another thing you might want to check is the softness/hardness of the tap water in your area. Your local government website should have that information. If the water you're using is low salinity it would buffer the nutrient uptake into your plants which I imagine would cause all sorts of deficiencies.

I mean seriously, how are you going to treat your water if you don't even know what it's composed of. At the top of this page there is a sticky on basic water chemistry. This guy knows his shit - I advise you to read it and then reread it until it really sinks in. The more you know about your water, the easier it will be to troubleshoot your plants.

Because really.. none of us know what the hell is wrong with your plants as we cannot be there to see how you operate. And if you're ignorant to the cause of the problem who knows if you even have a clue or would have a clue to share with us that would allow any of us to better assist you.

(and btw, I'm not saying you are "ignorant", I'm using the word to mean "lack of knowledge", so I'm using it as it was originally intended).

The high PH might be a symptom of something else, perhaps your tea isn't made right because to make the tea would mean you'd have to know how your water is going to interact with the recipe.

Water is one of the prime variables in this equation and it would help to know exactly what you're dealing with before you try to figure out your PH problem.

Another thing to consider, water temperature. You want to keep the temp around 74-78 degrees. Too high or too low will definitely cause some deficiencies.

First off i want to thank all of u so far for your help, yep evryone that responded thank u sooo freakin much

Thanks to u ALOT uniformed to where as i had no idea there was a water expert on the forums, and yes i will read up on his knowledge this weekend

I had no idea that my water temp affected my ph, i will have to get a freaking bucket then and keep my RO/DI water i use in like a 10 gallon bucket, or aquarium or something, i believe that could be my problem


Yes, u r correct right now im real ignorant to my waters ph, my god its so hard to keep control of, and hard to test, but i just found out i do have a HYDRO shop near me and ill be investing in a ph meter this weekend even if i gotta order a new 20 dollar milwaulkee 1 ill be getting a new

yes i wont be using any more vinegar now that i know its unstable i need to get some nitric acid, but i need to know how to add it tho, and i have no wayof testing for how much it brings my ph down until like this weekend, and i cant go that long without watering my plants, so im just gonna add a heater to my water put it on like 74 to 80 degrees and cross my fingers it equals it self out my god, my first grow wasnt as half as difficult as this one has been

Also if i havent mentioned on my soil grow im using a organic worm casting, and a organic jiffy soil mix

thanks for all the help thus far, and trust me your help wont go invein, everyone that helps me if u live in indiana, or if u wanna travel, ill give u a bud AND burn 1 with u

im growing white widow, shark shock, G-13 AK-48, and LSD, currently waiting on my LSD, and G-13 to get here but yes ive have unphed balanced white widow, and AK-48 growing as we speak

thanks guys!!!!

I'm sorry but you really don't need that electronic pH meter. The drops are more than accurate enough, you just need a little experience reading it.

Do yourself a huge favor and start using RO water. The price of two good pH meters would have paid for an RO machine by now and saved you a lot of hassle.

Also get yourself a bottle of pH up and pH down so you can reliably adjust it in the future.

thanks for the response, and i have a RO/DI unit, but i do not have any ph up or ph down

i was told if i use this that my organic soil would get killed because of all the bacteria suposidly in it??

but i guess it would be ok for the bubble bucket seeing as it is hydro

my ph chemical tester should be here by tomorrow, im hoping

thanks i hope it is enough cause im really not wanting to by a digital 1 right now, though i will invest in one later on

thanks!!!!!

Not sure about organics, do you need pH up or down?


i think i need both, but i wanna stay organic cause i herd that if i use a ph buffer that it will kill alot of the benifical bacteria in my organic soil, any ideas???

i know vinegar, and lemon juice for ph down is good for organic, but what about a good ph up!!!!
