Testing my auto strains

Hi everyone this week whent ok I have stopped feeding for now because of a high PPM in the soil. I tested the runoff and it was over 1000 ppm . I'm not going to flush it because I will just drown them and that will have no air . They have showed no sign of being burnt and seemed to be pretty happy so just going to feed plain water with 6.5 ph . This is why I normally grow in coco perlite naw because of all of the problems . Don't get me wrong I've been growing in soil for 15 years and I have learnt to get the right recommended soil for cannabis and just feed it ph water. Mixing your own soil just ends in high PPM . Thank you for looking and will be an update next week
