<span class="link_user">@Needweed</span>, no problem g, everybody is a beginner at some point ;)
I have around 300ppm in my tap water, but for some reason the water from my shower is 70ppm :grin:
For the watering I still use distilled water but I use this water with low ppm for the flush.

Thanks for answering, iam rly just a beginner. What about your ppm in tap water? I have 350ppm for example so i doont have to add a lot of nutrients to go over 500-600. Thanks
