2 weeks flowering PH PROBLEMS HELP!!!!

Ok my plant is 2 weeks into flowering and some of the leaves are curling in and showing signs of nute burn and such..... I know its due to just the ph fluctuation cause I have been looking around.... Im using advanced nutrients 3 part formula grow/micro/bloom and mixing with distilled water and watering once a day... I have no ph tester I will be picking up 1 asap but I read that the ph of distilled water was already 7 and with the nutrients im sure its even higher and unfortunately i just watered again =(.... I need something fast that will drop the ph a lil untill i get this tester tomorrow I cant afford any more dying leaves. Plzzzzzz help.

lower leaves or upper ones are yellowing? It is normal during flowering for the lower leaves to yellow out and drop off because the plant is pulling as much energy as it can to help produce buds. But upper leaves should still be nice and green.

Its not yellowing its more like the edges are burning and turning brown and crumbly along with some of the other leaves curling like each blade is trying to roll itself into a joint you know? I know its ph problems Im going to flush tomorrow with distilled water after dropping the ph from 7 to like 6-6.5 just to clean out all the acid still would like a lil insight though.

I just got 2 gallons of distilled water what can I add to drop the ph below 7 some so I can flush this girl out right now....?

flushed with 1 gallon of distilled water with a few drops of vinigar to lower ph a lil.. Goin to water with just distilled for a couple days and gonna pick up a ph tester and ph down.

Don't forget if you are using distilled water, you will need to add calmag to the water.
Either way, you should feed right away with a very weak solution of your bloom fert to replace the 'good' stuff you flushed out with the water. That's the very important last step of a complete flush.
Now, the pH of distilled water is actually more like 6.6, because you have dissolved atmospheric gases that lower it. But the ionic strength is very low so it doesn't matter. Unless you have a pH tester, you should not be mucking about with up/down! Adding nutes does NOT raise the pH automatically. That depends on what the nutes are composed of. A quality fertilizer is buffered at the exact range for cannabis, so if you use one that is desinged for the type of grow you are doing, and your soil is not sour already from overfert or the lime being used up, you should not have to adjust your pH at all.

Hey dagarden4me :thumbsup:

For sure, do whatever stinkyattic says!!!
She is like the Goddess of Ganja :D

My thoughts are you can't really go wrong with tap water, it has been PH balanced for human consumption, it's real close to what your plant needs.

Without a PH test kit it's a gamble to guess on the proper amount of additives to correct your PH. If it is off, without a kit it's hard to say.

Flushing is good to help correct the burnt edges. Just be careful adjusting the water PH when you really don't know what you are starting at and what you have ended up with.


Good Luck!!!
:hippy:

I added another link to my siggy... veggii inspired me this morning... lol! It's the second one; check out the long ass post on page 2 haha!

Apparently cannabis cures writer's block... :rolleyes:

Wow... I was so wrong. I just picked up a ph tester and tested my nutrient solution and ph wasnt to high but WAY to low for soil making it to acidic and burning my plants with horrible brown spots on a bunch of the leaves. I used the pretty cheep tube tester with the drops but it was below 6 without a doubt and im using advanced nutrients 3 part and it says to keep between 6.2 and 6.8. I tested the spring water we drink here from the zephyrhills springs and the ph was above 7 so I kept diluting the nutrient solution with as much as i Needed untill I got the ph somewhere between 6.2 and 6.8 im not sure exactly. Do you think this is ok untill I can get to the hydro store and get some ph up and down? And will the buring on the leaves effect the plant to much before its done, it still has around another 40-50 days left in flowering? Buds are starting to look and smell really nice and just dont want to be disapointed.

Thanks for the help

And what would you say would be the proper level ph for my nutrients that i should keep at before feeding daily? Im using advanced nutrients 3 part grow/micro/bloom in soil mixing in 1 gallon of distilled water. And I thought they were organic nutrients but i think im wrong...?

bump.

Make the pH of your nute solution such that the runoff from the bottom of the pots comes out around 6.7.

Diluting your water does not actually change the pH; to acidify, you need to add pH down, or in emergencies, a bit of cider vinegar.

Stinkyattic every post of yours that I read is always spot on, I am currently on my first grow and you have helped me so much already believe it or not so thank you very much for sharing your knowledge, much appreciate. Peace out.

add your nutes to your water first and let the water sit for a few before u adjust ur ph...i have a hydro set up and i read to do this in the cannabis bible, ive noticed my after i add the nutes to my water it goes from 7.2 down to 6.3. then i drop my ph and then check it a lil later. so my advise would be get ur water and nutes mixed then wait an hr or so, check ur ph and then adjust

I had these issues using advanced nutrients aswell, and i found cal-mag to work wonders. Also I think watering once a day in a soil based medium may be over kill for your plants.
