'Indoor Marijuana Morticulture (misprints interpretation?)

Where can I find out what those weird measuring symbols in Cervantes 'Indoor Marijuana Horticulture' mean?
one example in page 89:

"many growers use / cup hydrated lime and fl cup dolo"
(I assume it means 1/2cup and full cup, but assumptions are for asses. It also doesn't say what it is added to. A ft3 soil?)

"Do not use more than fi cup hydrated per ft3"
(What the hell is fi cup? there are fi cups and inches all over this book's edition. Will the fi's and fl's all mean the same measurement once someone tells me what one means on one page or was fi & fl a printers error where a measurement was supposed to be inserted, therefore requiring a different measure on different pages of the book?)

Otherwise, as everyone knows, its a excellent book. But without a clear representation of measurement, for mixing, it's pointless.

This question, & others the annoying symbols/shorthands will invoke, is the reason I joined this network.
Can I give Jorge's pubilsher this book back in exchange for one without the errors? Is there a place on this site or marijuanagrowing.com that interprets the errors from various pages? Seems like there should,at least, be one for those of us who purchased this book. May I suggest one become posted at marijuanagrowing.com considering it is his site and listed in his book? It may be several months b4 I can afford to buy his 5th edition.
Also, does anyone know if the 5th ed is prone to such critical errors?

Personal note 4 Mr. C:
You're still a demigod in the world of MJ(Shiva & Kali being THE ones), Jorge, so no offense. But how about a corrections post on your site, eh? Or a link to one if its already somewhere out there?
