Question

[Caper]

I have grown hydropnicaly many years ago things are not going like days of old i am using gh flora trio do i add nutes all three weekly or do iadd as ppm tells me to thanks

I use the Lucas formula for adding nutes to DWC. So if the plant drinks a gallon... and the reservoir is low, I’ll add a gallon of water plus nutrients for that added gallon. Then I do a complete reservoir change every 2-3 weeks.
