Hello Bili_R,
You did answer your own question.
Order a new pH pen, the cheap chinese ones will do for cannabis.
Make sure to water till at least 20% runoff when you water the first time with the right pH.
And one more thing, measuring the runoff from soil is useless. You need to do a slurry test if you want to measure the pH from the soil. Just google it and you will find how to do this.
Happy Growing Buddy! 💚

Hey mate,
yes your guessing right. Thats a slight nutrient lockout due to a wrong pH. Your plant cant take up the nutrient it wants, because your pH is out of range.
You can use citric acid to lower it, when i dont have ph-regulator i simply use lemonjuice. a teaspoon lowers the ph for around 0.5 on 1Liter.
Happy Growing, dont stress it👍
