As the days go by... Day 1: I use root tone for my clones and a root enhancer. At a very low ppm. Maybe 25 ppm if not just plain water. I have my ph at 5.5. After about 5 days you will need to water again. Pick up your tray and if its real light then it needs watering.
Day 14: On the second water I raise my ppms to 100. If I have a third watering it will be at 250 ppm. These are the kind of roots I like to see.
