Hello everyone ,

i have a question ,i have been told to not care or check the run off water PH if i grow in a living soil ,but im facing a calmag deficiency and tea or adding calmag didnt fixed it at all ,when i checked the run off water it was around 5.4 ~ 5.5 PH , from my research's i found that and quote " In soil, calcium is best absorbed by the roots in the 6.2 – 7.0 pH range (in soil, it’s generally recommended to keep the pH between 6.0 – 7.0, but calcium specifically tends to be best absorbed above 6.2) "
anyway you guys are the expert i need your advise regarding that .

thank you in advance

Run off ph being that out of whack is a sure sign something is wrong. Typically it’s from nutrient toxicity. If your using tap around 8 and it’s dropping to 5.5 that’s a huge swing. I’d say you have too many nutrients in the medium. Need more info and pics to know for sure.

PPM of the run off is around 3300 PPM , dont know if is that accurate ,but thats the readings .
Well im using NLS concentrate supersoil 1/3 of 5 gallon pot ,and 2/3 peat+vermicompost + perlite mixed + adding 1 Lb of the concentrate as the company instructions .

i use RO water ,i thought thats the reason ,but i add calmag and still getting worst , and also it was the time for compost tea feeding ,and still after 3 days buds not getting fatter as it's supposed in that stage ,it's like stunt growing .
humidty - 40 ~ 60 % always , temps 19-20 C at lights off 21-22 C ON , i dont think its temps issue .
watering every 2 ~ 3 days ,and never overwater , i just water until i see some drops run off thats it .
soil PH its the only thing that im not sure about and i never checked it and never had to do it as in my whole growth cycle never had any deficiency at all.
do you think i need to adjust the soil PH ? and how do i do it , we have Garden lime available in our stores where im can i use it ?

Deficiency getting worst

Hi there here's a previous thread i posted when i noticed the beginning of that sign which they told me " calmag " deficiency CLICK HERE well from there until now i did foliar spray just a few fan leaves and watering with RO water 40 PPM before ,and after adding calmag went to 180 PPM. 3...

In soil use tap. Tap water only until your ppms start going down. Since you have a toxicity get 10-15% run off just to make sure the excess is forced out. Just do it super slowly.

After looking at your pic it looks to be a few different things going on. Most likely getting ph proper and excess nutrients out is going to be key.

6.5 ph water only

I prefer to use oyster shell flour to raise the pH, but lots of people use lime. Just make sure you really need it. Oyster shell flour is a lot more forgiving.

What have you been feeding them? Have you been feeding lots of acidic nutrients?

i have been using R.O water without even calmag in my whole cycle with 6.5-7 PH , 40 PPM ,my tap water has chlorine and its so fked up like 700 PPM .
should i just water like usual but with more run off to wash some PPM out ? do u think thats what u was gonna do in my place ?
thanks for helping <3

You tap is 700 ppm? That doesn’t sound right. Mine is about 250. If your tap is 700 maybe something is wrong with your meter.

i fed them nothing but R.O water 6.5 ~ 7 PH whole growth cycle with 40 PPM, i use NLS supersoil https://www.natureslivingsoil.com/original-concentrate
, oyster shell flour is not available where i live but i saw that garden lime once in some store ,i can buy it.

Nobody has asked this question yet, so here goes...

Are your plants having issues or are you just worried because your run-off is testing at a low pH?

I also wouldn’t test the pH of the runoff, instead take a few soil samples from a few inches down, make a slurry with that, and test the slurry.

Have you been top dressing with that stuff, and what soil did you mix it with at first?

i top dressed once before two weeks ago wih the same concentrate ,as you can use their for tea or top dressing too.
my soil is mixed of 40% peat + 30 % vermicompost + 30% perlite in 5 gallon fabric pot ,and adding 1/3 of the pot mixed of that concentrate creating a supersoil layer.

Yes im having a calmag issue as the pics shows in this post CLICK HERE
all possible reasons might cause this issue has been figured and found nothing related to them " temps ,humidity ,overwatering ..etc " ,problem getting worst ,i start facing that in my week 3 into flower ,and still does and im in week 5 ,i beleive that defeincisy gives you small bad looking buds which i dont want that to happen :(

Part of your issue is that you are in small pots. I was told to go no smaller than 10gal when I started my current organic grow. I’m new to organic growing, too, but from what I understand you need to keep feeding the soil to keep it going. I give each of my plants 1.5L of tea, once a week, and every now and then I top dress with my dry amendments and some worm castings. Also, if you are watering until you get some runoff then you may be watering a little too much. For organic soil you don’t want to let it dry as much as you would with salt based nutrients, and you don’t want to water until run-off. You want to water it less, and more frequently, to keep the soil moist but not saturated. I had a hard time figuring this out, went with a blumat system, and that made watering a non issue for me.

Thanks for that specific detailed information's really find it easy to understand the idea of watering and how to water ,i left them many times dried so much ,but my watering never went too far with so much runoff ,i water them like almost 99% with a few run off .
i use tea every 3 water feeding ,started from week 1 flower .
well i think i will just keep do what im doing and hope and pray for the best :D

I think you probably used too much of that stuff.
