A quick word from the heretic:

I have tried to do the fertilizer-with-water thing in the past, and I still
do it for special plants, but with over 500 pots it takes a long time to
fertilize everything by hand and I end up forgetting to do it on a regular
basis. I also tried adding dissolvable fertilizer to the dripper system, but
I got the impression that it was dissolving all at once and dumping all the
fertilizer at the ends of the drip lines.

So I started putting a complete granular fertilizer with micronutrients in
every 8-inch (20-cm) pot, each time I repot (about every three years).  I
use a couple of tablespoons (30 cc's) per pot. This is horrible
overfertilization according to many folks, and I've seen growers flinch when
I talk about it. But I'm focused on what works. Sometimes I see a bit of
leaf tip burn that I think is related to fertilizer, but I also get rapid
growth from my plants and a lot of flowers.

This approach does also result in rapid growth of my "indicator plants,"
