Not to sure where to put this but any way here we go. I’m growing auto flowers in fox farm happy frog soil and today was the first time I checked the ppms they were over 3000. They are in 3 gallon fabric pots and I have not given them any type of nutrients yet. The pots are re used from last grow. So my question would be could there be left over nutrients built up in there that didn’t get rinsed out that’s causing those type of readings
