As a lifelong fan of Crypts I'm blown away by the species here, many of which are known to be "troublesome" (esp. keei). It sure takes a while to read all this but good on you for posting so many pictures!
Two points: 1) back in january when the osmocode root balls made things go bad - too much nitrate at the roots too quickly. Better to get some clay, mix it with manure that's been wetted then dried, twice. 2) What's the CO2 at? What light is on that now? Crypts will put down their leaves parallel witht the substrate under (what they think is) high light. To get them to reach up and have nice pointy tips screaming upwards you want as much co2 as you can get and not that much light. Then try extra hard to reach the "sun". A gro-lux tube helps too, the extra red light stretches them a bit, red is filtered out of deep water very quickly (unlike blue which makes plants more compact; red elongates) and this puts some of it back. An incanescent/halogen bulb would do that soo, or I suppose high powered red leds.
Such a great effort! Thanks for taking the time and trouble to document it so thoroughly!
