Expl0reranswered grow question 4 years ago Thank you very much for that quick and excellent comment. I will try to fix the issues.
I have the power supply at 600ppm.
Tap water is 340ppm here.
i started feeding yesterday as indicated in Vitalink's schedule. But then I took the minimum. instead of 1/2ml/l I did 0.75ml/l.
With a bit of ph down this resulted in a ppm of 600.
What can i do?
I should use filtered water with nutrients?
or can I only use tap water without nutrients till they have grown bigger to consume a higher ppm?
