hello friends i ve feminized lemon haze og plants in peat , i ve issues with soil ph im water them with acidic water but its keep raising wathever i do, and i decided to give liquifided elemental sulphur is anyone tried this ? i read its safe
peat haz a lower PH value i c u said you r using peat moss which has a lower ph value plus u using acidic water what PH r u looking for n soil 6.3~6.8 is what u need ..
you are using organics I would leave it alone I don't know what your plant looks like but if it looks good why worry. A lot of people don't ph in organics that is supposedly one of the benefits. I think you are chasing a ghost....imo I never ph out always in and I have had no problems
İm trying to grow since 2020 and i disnt been successfull yet because they are dying middle of flowering stage but i think this time i found the problem after the clones get big enough i saw roots coming out of the soil and they look like dried i tried to bury but they kept coming out so i found its root rot . They are yellowing and dying in 3- 4 weeks of flowering
u r using soil and peat moss as your medium that don't sound good 2 me but then again you said u don't have a problem until flowering you may have used up all your nutes out of the soil have u check your PH pin u need 2 add flowering nutes do u water/feed until u have run off check out growweedeasy.com lot of good advice u can learn a lot .... my 2 cents
i use 2 make my own compost never add peat done very good 4 me ... the medium i use now has peat n it and they add a buffer 2 it 2 keep PH n a range of 5.5~6.5 i use 5.6~ 6.2 i have been using 6.1 looking 4 more flowering nutes .....
What is the PH raising to ? Peat itself is acidic 4.0- 5.0 so the raising of your PH must have something to do with the input water you're using, or amendments like compost that have been added. Here's a look at what watering can do to PH.
Leaching washes out nutrients and raises pH can do to PH.
Fig. 2 shows an experiment by Angelica Cretu at University of Florida where she added increasing volumes of pure water to a peat/perlite growing medium. The medium had an initial nutrient pre-plant charge using water soluble fertilizer that raised EC to 2.1 mS/cm using the saturated paste extract method. By the time about one container volume of clear water was washed through the substrate, the nutrients were almost completely leached out and the EC was down to 0.4 mS/cm. As the substrate-EC declined, the substrate-pH increased. This effect also happens under mist propagation when excess water washes through the plug tray and pre-plant nutrients are leached out.
Fig. 2. Effects of leaching with clear water on substrate-pH and substrate-EC.
Cation exchange capacity
Peat is naturally acidic, and lime is usually added to the substrate to bring pH to around 5.6 to 6.4. Lime is typically calcium and magnesium carbonate. The lime reaction adds base (carbonate) that neutralizes acid from the peat. Lime also supplies calcium and magnesium.
Calcium (Ca2+) and magnesium (Mg2+) are examples of nutrients that have a positive charge and are called “cations.” Acid (which is a proton, also written as H+) is also a cation.
The surface of peat particles has many negative charged locations called “cation exchange sites.” These negatively-charged sites attract positively charged ions, because the peat and cations have opposite electrical charges. The cations adsorbed to the peat include nutrients such as calcium and magnesium, and also protons. The “cation exchange capacity” or CEC refers to the amount of cations that can be held at these exchange sites by a certain weight of substrate. “Base saturation” refers to the percentage of exchange sites occupied by cations such as calcium and magnesium, rather than protons.
Adding lime before planting tends to saturate most cation exchange sites with calcium and magnesium, displace the acid on the peat, and neutralizes the acid with carbonate. Nutrients are also added to the substrate from other sources, including fertilizers and irrigation water.
Adding calcium and magnesium displaces acid protons (H+) from the unsaturated exchange sites. These displaced protons move into the soil solution and drop pH (Fig. 3A). In contrast, leaching with clear water removes cations such as calcium and magnesium from the substrate exchange sites and soil solution. Protons in the soil solution then adsorb back onto the peat, which raises pH of the soil solution (Fig. 3B).
Liquified elemental sulfur is pretty much car battery acid man I wouldn’t recommend to use that until you really know what your doing. That being said I seen people mention peat, there are 2 types of peat - sphagnum peat moss & plain peat moss.
The Sphagnum type has a ph around 7.0, an the regular peat has a ph around 5.0. If your having trouble with the ph tho, my first question is are you using tap water?
Tap water from where? Southern Ca. has the worst tap water I have seen next to Mexico. I sent a sample into Culligan and they recommended Sparklets if I couldnt get the dead animals out of the res.
never had a problem like that when i used soil but Sulphur does lower the PH ... have u tried flushing then come back with the wright PH ??

when your PH is n the seven's something ain't wright ....
i can understand that with u ....

This is root rot right ?

I dont know anything about soil growing but I do love a good chart
Hi!
Well a slightly acidic soil is the best for marijuana, like roses
I always have a tendency to believe that nature knows what to do and let her do her thing…However…
If you want to organically raise PH you can add a solution of white vinegar and water.
For lowering the PH you can make a solution of baking soda and water
Hope I am not out of subject…Good luck

Odessa Texas that shit catches fire. lol They don't drink it unless it is bottled
I only drank Lone Star when I was there, I thought anything besides Lone Star and Ice Tea would get you hung
some visuals would be nice..

@ Persian Farmer, my friend you have that PH comment backwards ! Vinegar lowers PH Baking Soda raises PH .
how are you measuring your soil pH??
They always claimed the acidity in the soil in KY is why weed grows so well there, tobacco & cedar trees like it too
I forget depending on your location the difference in water...my water is 7.3 ph and 100ppm...
So yea your right Josh...
