If the meter is flashing x10, multiply the number by 10.
so 166x10 = 1,660ppm
that's quite high, for most plants. depends on where you are in your grow. More information is needed.
You want to be measuring your TDS in 1L then multiplying that ratio for how large your reservoir is.
If that cup is a solution you prepared from the main tank, then it might be to high.
If the entirety of the teaspoon/nutrients are in that little cup, that might be why the reading is so high.
Over all need more information to know if its to much or little. But I'm guessing its to much,
Best Of Luck and Happy Growing

Yellowing a bit too soonDuring the second week, leaves started to look a little bit yellow. The first true leaves yellowed way too soon. I'm guessing lack of nutrients. It never showed signs of drought or overwater stress. Your thoughts?

Help with sex of plants. Regular seeds, not fem.I’m concerned on the sex of a couple of plants I have. I diagnosed a couple as male last week and removed them, about 4-5 weeks old. This week I am noticing growth in the others and am concerned so looking for experienced input. 1&2 appear to be female to me with calyx open? 3 M?
