I've seen another guy who mixes the fertilizer into the water and pours it directly onto the media and roots. However, he only does it after he's watered with straight water first. Supposedly so they won't overdose on the fertilizer. They'll absorb the straight water first and not have a lot of room left for the fert. water.I've seen another guy who mixes the fertilizer into the water and pours it directly onto the media and roots.

This is about what I do. Working a shelf or two at a time I take them to the bathtub, run the shower for a minute or two so everything is a little wet, wait ten minutes then using a watering can, fertilize. Then I wait another ten minutes, carry those ones back and move on two next shelf. I do the wetting down thing because its really not a good idea to fertilize dry roots. It takes about 5 hours two or three times a week and is a total pain in the patootie. Lordy I need a greenhouse!!!
