Regarding ppm

so I'm going in FFHF soil in 3 gal fabric pots. I finally got my ppm meter today and tested runoff at 2700 ppm. This is crazy high this i know. Im on day 23 from seed and have fimmed for the first time and am doing lst. Ive added 1/4 strength grow nutes 2 times, once per week and added cal mag once. I started with tap water testing 156ppm. Then switched to distilled as I can better control things. I tested unused FFHF at 630ppm. So I guess my question is... why is ppm so high? Is it my ph? Please let me know

What nutrients are you using?

What is the ppm of your water after adding nutrients?

Day 23 from seed means they are still quite small. You should be fine with the FFHF without adding any additional nutrients for a while.

Any pics?

Every time you water, are you getting about 15 - 20% runoff? This helps prevent salt buildups. Usually when I see such high numbers it's due to the plants being watered just enough to prevent having to empty saucers of runoff.
