OP, upgrades to crafting leveling gear post 50 (or rather after ARR) typically happens in two level increments (51, 53, 55), (61, 63, 65) etc. The idea behind HQ leveling gear is it allows you to skip a tier of NQ as far as stats go. The only way you are going to get HQ though is to either craft the gear (either yourself, or someone does it for you), or buy it from the MB (crafting/gathering gear is usually really expensive).

As others have mentioned, you can just buy the NQ stuff from NPC vendors at various hubs and merchants in the towns/villages you visit. This should easily get you the stats you need so any recipes that are grayed out in your log become available. If gil is an issue, then you don't have much option other than to gather your own materials and craft the items yourself. You would need to look at your logs to see which crafting set closest to your level is available for you to craft.

If you've hit a roadblock here that usually means that you are leveling faster than your resources allow you to.
