First Time Hydroponic. Somethings off

You need to have a fresh sample try increasing your next infeed to create more output to test.
Can you supply info on water input volumes I see 4 per day but no volume.

okay i will handfeed them a bit more in a few hours and see how it goes.
Currently only 1 ring per plant is connectet. Water input is 2l/m per Ring. Always for a minute. But with the tube and its length its probably more 1,5 l/m

Okay so i check the fresh runoff an its still the same.
Input was now EC: 1,3mS
Output was the same as last time with 2,3mS
