For heavy feeders like Crypts or Echinodorus, I'd give each one
a stick for themselves. Wells since Crypts are often growing close
together, maybe a half stick for the large ones and a quarter for
smaller ones. It really makes em grow!

Looks pretty good indeed. You might want to add chelated iron although
your soil substrate should supply a fair amount of Fe.

I've used Jobe's Plant Stix but yours also seems to have a lot
of micronutrients. What's your water like? Does it have calcium?
