Soil "flush" to clear salt buildup Y/N?

Thanks for the quick and very thorough response. I do use a EC PH PPM pen to prepare my feed an have looked into the 'correct' ratios(cause so many people have different an conflicting suggestions) But also regarding fox farm products feeding heavy an recommending flush to basically have you get more product an all that, I mean didn't think of it like that🤔 but yeah I mean sounds like a standard business model 😮‍💨 but yeah this is what I needed to hear, appreciate it @m0use thanks 🙏
