First PPM Reading - Feedback Appreciated

  • White Widow CBD Autoflower from ILGM
  • Method: Soil-Fox Farm Happy Frog
  • Vessels: Plastic 3- gallon Pots
  • Light system: Bestva 600W LED

All three (3) plants are 21 days old. They all are green and healthy-looking. PH is in good range. One (1) of them looks like it has the start of a flower.
Today my PPM Meter came. As they had not been watered for four days, I split a gallon of distilled water with 1/8 of a teaspoon of Foxfarm’s Tiger Bloom and 1/8 of a teaspoon of Grow Big.
I collected the runoff of all three into one container.
The PPM said 1,702
any input is greatly appreciated.

Also, all the pots have holes and a tray underneath to collect runoff. But, in the very bottom of two of the pots, I put some small rocks, (see pic), and now I’m wondering if that is gonna screw up the runoff reading?

I forgot to add:
all the waterings up until today (today was the first time I used distilled water) have been in de-chlorinated tap water which has a PPM of 343

I would recommend adding cal mag if you continue to use distilled water.

Okay, thanks. I will.

Closing this as you have the same thing on another thread.
