Ph of water is about 7,5. Lowered it to ~ 6,6 - 6,7 (lemon acid) and flushed the plant with approx. 2 litres of water.
I was really impressed, that flushed liquid had ph about 7,5! That means that real soil ph level is up to 8!!!!
Damn...
Can I lower soil ph with permanent watering (provided I lower water ph to about 5,5?)
