How do I measure them? I am using a basic plant food 5-5-5 which I double up and add liquid nitrogen but I would I measure these dry form plant food to water as I want 5-20-10 I always use a 2 gallon bucket just under the rim plus anything that spills.

If you're doubling up a 5-5-5 and ADDING nitrogen, how on earth are you ending up with 5-20-10 or even think you are going to end up at that? Im a little confused or just outright not understanding your question.

I'm sure somebody should chime in. Myself I've been under the lights since 1985 and have never found a need to do something like this.
 I have a little experience.

I have no experience with this math yet, but I've been reading up on it. Here's a link to some helpful info on the subject.
