Techniques. Defoliation grow question by LittleBigTrees

LittleBigTrees started grow question 4 years ago

why does my soil PH keep going up ? I'm adding water at PH 4.5 and feed at pH 4.5 (alternate) to try and lower it, I add 4 litres and have run off between 1-2 litres but the run off is always 7.4+ at first and 6.2 after the run off.is this normal ?

Just a small thought...in the podcast i listened to tonight they mentioned that soil that gets dry has a tendecy to have the EC and such go significantly higher. They were stressing the importance of accurate and consistent watering practices. Do you ever let the soil get just a little bit dryer than you'd like? Or have some days that you just skip watering? I know im guilty of having some longer dry periods until i realized my 1 gallon pots needed water every day and sometimes twice.:v: i hope you find the solution. I know soil does have incredible buffering capacity though so if your ph is staying below the 7-7.3 range i wouldn't worry. Ph runoff seems to usually be higher than the initial input water. Perhaps the nutrients and the organic material both cause it.

the soil is alive with micro-organisms that basically will exist and digest things etc and this process will balance out to a neutral pH for example 6.5 Hope this helps ! :rocket:

Hi,well i never measure ph of my soil grows,. only if i have any problems with the girls. Soil is able to regulate(buffer) the Ph by itself. And i never had problems. Just 1 time when i try to regulate the Ph in my soil ( my first indoor grow) it ended in a total mess. Since that day i know plants are ok in my Soilmix. I only measured the Soilmix before uisng it. with a soil measure kit

It vary's from what the PH in the soil will be , and how much nutrients are there already . This plays a big part on why your run off might be a different PH then what your feeding . When you feed what ever is put into the medium will get used up over time there for changing the PH slighty over time . This is normal if the numbers are to drastic then Id say you have something to worry about but based on what Im seeing and what you are saying its pretty normal . I hope this information helps shed some light as to why your PH run off is different then the PH that you feed with. Other then that your doing a really good job and it looks awesome ! -Happy Growing!

its normal that you get higher ph in runoff.

Because the soil have buffering capacity so it will tend to get back to the previous PH but I would not water with 4.5Ph and I would not check a soil runoff value. To know the real PH and Ec values I recommend you to bit a soil PH tester ( generally testing PH and moisture level of the soil )

why does my soil PH keep going up ? I'm addin...
