raising and lowering ph

[greenmatter]

also POWDERED dolomite is what you need MO. run it through a coffee grinder if you cant find it. look for the growmore brand if you have to grind it. your woman will not be happy with what this does to the blades in the coffee grinder. just sayin'

the pro mix hp that I use has peat moss chunky perlite and it says lime for ph balancing but doesnt say how much. Thats absolutly everything in it. The dolomite I got is 65 ag, its a fine powder already so I dont think any grinding is necesary. I got the dolomite today at the growshop so it should be what I need just not sure on the ammount. When I said 6 db that was cause Im using 3 gal cont. so Ive heard from 2 teaspoons to 2 tablespoons per gallon I realy want to get this rite. When I asked about how much lime is in the promix they dont know just say not much. Not enough, is what I was told.

oh and my ole lady isnt happy with a lot, just sayin lol

 

[greenmatter]

never grown in the stuff so i have nothing for you first hand. it is a peat based medium so i would lean toward the higher dosage, but there is already lime in it so it gets sketchy from there. see if there is a promix thread in here, some hands on experience is what i would be looking for.

when u add ur nutrients it will change ur ph so I wait until after all my nutes are in then I adjust my ph so theres no guessing. If u had some pics of ur plants it would help a lot or a better description of what the problem looks like but if u flushed good and water back with correct ph balanced solution make sure u have enough mag and cal that can cause a lot of problems, some strains more so than others, I dont know how or what u feed but if u use the bottled nutrients u need extra mag and cal u could mix lime with ur soil before a grow and u can buy cal/mag as an additive to correct and prevent those deficencies.
as for the drops Ive tried em and just personaly, mabee its my eyes, but I cant tell the differance in the colors there so close. But thats so much better than nothing. What are ur temps and also make sure ur not drowning ur roots the soil should be ready to water again in a couple of days.
I actualy spent a summer in Denmark and I know it stays cold is why I ask about ur temps. It should be about 75 at ur cannopy top and good air circulation is important.
Ur temps can be higher if u supp with co2, but if not u should keep em around 75f I think would be best, of course other pep out there please give better info if I am misinforming, I dont want to steer anyone wrong, I ask becasue I grow in hydroton and also in promix but I qiut growing in soil years ago, and I also co2 inhance so my temps are higher also. Mine run mostly at 85 sometimes 88 but just a little and thats at the top of my cannopy but with my co2 at 1500ppm thats a good thing. They grow faster that way.

Thats also what i have seen, that my pH change when adding my nutrients, but how important is it to let the water be for some time, and how long time is that, is it an hour or 2, or maybe a day or so, before doing anything to it?

My problem there is that i dont have so much room, so i cant store 50L ready water for making that trick, but does that have a big effect on my problems?

I will just show a picture, maybe you can tell me what's wrong, but i think myself it's maybe because i havent adjusted my pH in soil until now, and maybe my pH in the tap water is too high.

Here is my Affigum, seem's ”OK”, but it also looks like i have been flushed, and it havent on that picture, but i flushed them all today with pH adjusted water using a manual test strip color thingy (dont know what it's called)



Same plant, another camera (dont have macro on both)

Full format to see it better:



Im not 100% sure what you mean when you say lime? Is it lime on Danish also you think? Maybe citrus?

Is it something that you can buy specially for plants or what? Im not sure and i dont want to add something when i dont even know how much to add, my plants work fine, they just seem a little strange, therefore im thinking what i can do better, i have seen many grow green plants, and first last in flower they start to turning in color sort of speak, hope you understand me

My temp is approximary 25-28 degrees celcius, somethimes a little higher, it seems like my fan is a little to little to hand the job (18cm dia) and 740m3/H.

Im growing inside my bedroom, so the lowest temp are around 20 degrees celcius, so i dont think that is the problem longer even if the leaves seems a little burned, and seems to die slowly.

About watering i only water when the plants are almost dryout, i have killed some plants before on that becost.

About my setup, it can been seen here :

I'll be back later folks, im not so good to english, so i have to read it several times to understand!

Thanks for the help so far.

the more times you ask about ph in soil the more different answers you will get. i always add lime to the soil so i think that is what works, while i do check the ph of the run off now and again the only way i have ever adjusted was with my nutes ( bubbling or not). i have never had to adjust that far. some guys on this site who know their stuff say ph in organics does not matter anyway. all my soil is 100% organic but i still check it. lime your soil and i things should work out.

Can i ask how much lime do you use and is it lime fruit as i understand it?

I havent heard about adding lime before, but i will check this out!

Ahh, just reading and reading, the dolomit is maybe the one with lime in? I have plans for using that and perlite and clay pebbles and then a good soil, and then adding my nutrients on it's way. but then i have to adjust pH anyways, right?

NO NO NO not lime the fruit. i wish i spoke danish as well as you speak english. i know the german word for lime is kalk. what kind of stone is travertine? in english its limestone. hope that helps

Maybe "dolomitkalk"?

This is why misunderstanding happens!

But what will you folks say about my plants, not looking too good?

i am no plant doctor but i think you have to little magnesium and some other micro nute things going on. how many weeks in are you? post that pic in the infirmary. plenty of info to be had over there

I know! But im open to any suggestions!

It could be right, i havent been so generous with my nutrients, and they are about 14 days from harvest, if i harvest 60 days after they went into flowering.

Ok, i will try to find this infirmary you are refering too!

Thanks for the help, i hope my next grow will go a little better, i have done one grow before this one, and that was the same, but got 410 grams dry on 600W, so i think it was "ok" for a beginner.

forums then cannabis infirmary and you are there. if i found it anybody can.

Thanks alot mate!

Im not so good to find the things in here, theres alot to find!

But i guess it will come with time.

Have a nice day, i will go get some rest before i read more english!

Try ph up and down by GH

 

[Spotten]

Thanks for the help to you all!

I will try to mix my soil with dolomit and perlite and claypebbles and then i will also adjust the pH as i have done before to, and i know it's not to low, i use 3 ml pr 10L water approx and i got my old pH meter to work and got i calibrated, and my tap water is 7.7 - 7.8 and when i add 3 ml pH down to 10L tap-water, then it says pH 6.5 approx, and that i think is better than the too high pH, and i will wait and see what happens, and like someone told me in here (cant remember the name on standing foot), then i will measure the water draining from my pots, but im not sure what to look after then?

If i do as i just wrote when adding pH down and then nutrients, without letting the water stand for sometime and without bubbling it with a airpump with an airstone and then just add my nutrients directly, what should the pH then be at the drained water if it's lets say 6.5 when watering? Lower or higher or same?

In advance thanks, and thanks for the help until now, sorry im so slow when im typing english, but it seems to be okay, got some pretty good answers!

Thanks peepz!

basicaly the same. When u measure ur run off it will tell u if there is a build up of nutrients in the soil which will let u know if ur plants were eating everything u were putting in or not. If its a high ppm comming out then u need to find why they werent eating the food. Many reasons it could be, ph probly being the culprit if ur not overfeeding, or killing roots,
you should try to maintain a constant ph, close to the same everytime, whatever point u choose to set ur ph at, u shuld always keep it the same or as close as u can.
U dont want the ph run off water to be out of whack. U want it to be where u want ur overall ph. Im no plant doctor but thats the best of my knowlede.

Ahh on that way! Sounds prette easy i think?

It's ”just” to get the pH the same as you fill in your plants when draining, then it should be ok?

Thanks for the help and your guide sounds pretty easy to go and sounds not like it's totally wrong, so i give it af go, but i will still post my picture in the imfirmary as told!

Thanks again, Greetings Spotten Denmark.
