My plants sick...duhhh its the PH

[racerboy71]

Yes hex, pH is important, this is not debatable imo, that's not sayin u can't harvest if u don't check pH tho

PH is not important if you're growing in soil.. can't stress this enough.
How many people that grow other plants aside from cannabis check their pH? I'd say very few. Been growing veggies for a good decade or more, never once ph'ed the hose water they get. Get tons of big ass tomatoes year in year out.
My moms been growing house plants since I was a baby, she probably doesn't even know wtf pH is, yet she's got a house full of thriving plants from African violets to rabbits foot ferns.. never an issue.
But people start to want to grow cannabis and suddenly they want it to be a science project... its really not that hard... water them when they're thirsty, fed them when they're hungry, give the roots room to grow, and have healthy leaves and that's about it...
Like I said earlier ... if you drink the water and don't die, you're plants will do just fine..
If pH was all important, I'd never have grown a single bud as I don't pH poo, and my tap water is over 8 pH.

Danm racer your the shit, I use RO and have to use pH up all the time, if I don't my plants go all deficient after a while..i feel there are alot of variables to just say " you dont need to pH in soil"..but hey I could be wrong, I think ill still pH anyway

CRAZY!! the people i know that dont check there pH use nutrients that have pH buffers, what kind of nutrients does your mom use? i never pH tap water or let it sit out for hours but i always check and correct pH of feedings

what are you feeding/not your plants to see deficiencies ?
i like to cut anything out of the system that is unnecessary, i found PH adjustments or measurements to be unnecessary, i use tap water and 2 part hydro food, no other additives

My post clearly states I use RO, after I fill my res with feed my pH is suppr low, I have to use pH up...just cause you use tap dosent mean everyone does, just cause ur tap is fine, dosent mean everyone's is..

.and comparing a house plant to a indoor MJ plant is just silly to me

Why are you talking about house plants ?

if your system is PH dependent that's a poor design imo

i am aware you use RO water i read that ,from your post above
i am stating what i use .. is that wrong ?

why would you assume that i assume everyone uses tap water ?

you seem to have a gripe about your water supply or having to regulate your PH,
why not change your system if these things are not satisfactory to you ?

I've started using tap water -> calmag -> cocoA&B with no PHing, no adverse effects yet. Soilless makes a bit of a buffer though, and my area has pretty good freshwater reservoirs.

I believe PH is pretty crucial when you're starting plants, but as they get older they get more and more tolerant - that is unless you're constantly out of whack for a long time (growers getting used to a certain amount of PH adjuster, and their water content suddenly changes i.e. spring).

Holy crap guys, seems like theres a pretty common answer going around these days in plant problems. The answer im talking about is, "Well your ph is off". Im starting to realize that that means you have no idea what your talking about. Nutrient lock out from an improper ph on a plant less than a foot tall to me sounds pretty rediculous. Theres usually a really easy answer to the problem you just have to find it by asking questions. A couple times since ive joined i have seen threads started and the first post is the problem with no info on the plant, and the second post is some jabroni saying....duhhhh, it s ph. AAAAAGGGGGGGGGGHHHH !!!!! No its not! Provided your water is close to the proper ph theres alot of growers out there that never ph adjust the water that goes in our plants, but we know that things go wrong all the time when your brand new to this. Most of the time its grower error thats causing the problem. You just have to be able to find where they made it. If you dont know, dont help is what im trying to say. Im not sayin that theres no plants out there that are suffering from ph being off but wow, this ph off comment is turning into a calling card for i have no idea what im talking about, but it sounds like i know what im talkin about right?

omg alien your pH is so out of whack you got a yeast infection LOL

 

[Situation420]

pH and Alkalinity are the two most important things that determine crop quality and yield. It's a known fact, improper pH or Alkalinity levels are what leads to a number of root zone problems and nutrient uptake issues. The differences in yield and quality is almost unnoticeable when pH is kept between 5.5 and 6.5 in hydro and 5.8-6.8 in soil. Outside of that range you start to run into deficiency and growth issues along with many other possible problems.

 

[BygonEra]

There's no question that pH is crucial in hydro... in soil there's a broader acceptable range and it's much easier to maintain. But I disagree that pH isn't important in soil... it is VERY important, but it's also harder to screw up.

Ph changes in soil comes from what you put in. The soil you start out with may be too acidic or basic. The nutes I use generally lower the pH quite significantly. Luckily my tap water comes out around 7.5 to 8, and after I add my nutes, I get around 6.5-7 with 5.5 run off. If you don't CHECK the pH of what your plants are growing in and using to grow, you sure can screw it up and it will definitely matter! But it's perfectly possible to grow cannabis (and all sorts of other plants) successfully without testing the pH in soil IMO.

ph is a big deal

 

[Alienwidow]

If ph is such a big deal then how can plants even grow in soil thats not perfect ph? According to some people on the thread lock out will deprive plants of some vital nutrient and it should die in no time from lockout right? you look at a map of plant species all over a continent you can be sure that the ph on every river bank isnt the same, but willows thrive all over. As racer said. Growing things from the ground doesnt have to be a science project. As soon as people realize that theyll start saving alot of money and the part i like the most is that im saving time. Science project style grows take forever to feed and water.
Have you ever seen california monster grows out door? 15 foot plants or higher in some gardens, fifty gallon grow pots. Twenty gallons of water coming from a hose, not a big bucket of phd water that sat out overnight, or river water pumped into water tanks. Phd? No way brother. They do amazing, and thats because they have what they need, light, dirt, water, and food. Not ph up or down.

Omg sunni, ph and yeast infections? Eeeeeew, i just barfed in my mouth a little.

most water treatment plants pH the water with calcium

pH of tap water doesnt need to be adjusted because its not out of this range 5-8

some nutrients when you mix have pH lower then 4 and it will reduce your yield

Your right. As stated as fact. MJ has an optimal ph. This is where it is happiest and will give the best results. This thread is turning into a debate on the absolute importance of the ph which is not what it was intended for but whatever, lets battle it out.
The question i have for you hex is if your growing a 12 oz plant in dwc which isnt hard, how many dollars will you spend to try and keep that ph constantly the same. Its going to rise every day and youll need to always ph balance your water at rez top offs. A 12 oz plant takes about 5 months from seed to chop and honestly what do you think costs more, two gallon jugs of ph down 200$, or loosing a half oz of that plant? And holy hanna, if your nutrients are bringing your ph down to four then i think its time to rethink the plan cause youll be spending more money than your making on blue and orange juice

You must REWLLY be a newb.
I've been here since June of last year, and my fav. thing was if it was ailing, and somebody didn't know what to do, the suggestion was "Throw Cal. Mag at it".

Using GH after adding 3 tablespoons of micro and 5 tablespoons of bloom to 4 gallons of tap water the pH comes out to 5.6-5.8 so Zero pH up and down is what i need for hydro

for soil i have to add pH up to get the same results

for random shit i use like CalMg+ i have to pH up cause its super acidic

i dont pay for GH's pH up or down i use botanicare's cause you get a higher concentration for a lower price ...so i dont buy anything blue or orange, my shit is clear

No man, I haven't even checked PH since Oct of last year.
