Drip System run off

[singlorigin]

Runnin a drip system for 32 plants in 20L pot with 1 dripper in soil+vermicil+perlite mix.

Schedule for watering is 3x55 min and each plant gets around 3 L of water.

But should i be worried that they don't get almost any water run-off?

I have also increased the watering from 3-4 times a day still i think i get less then 10 % water run of.

What are you feeding? Ec ? But yes, if you aren’t getting sufficient runoff you will build up salts and burn pretty quickly.

Now im in 4 weeks of flowering and EC is 1.2 but i dont go higher as 1.6 wit Wedding Gelato strain .
Just found a thread that i should flush with clean water with PH 6.5 every 3 watering time to get the runoff and I should be fine .
