How can I craft the level 50 two-star recipes?

Most of my Disciple of the Hands are level 50 now and can craft the one-star recipes just fine. The two-star recipes require 347 Craftsmanship or 318 Control, but here I'm coming up short.

I have the blue tool you get upon completing the level 50 crafting quest, a left side of HQ Patrician's Gear, the one-star green offhand, and a right side of HQ electrum gear. Yet, I'm still around 30-40 short on both stats, and I cannot unlock the master recipes without two-star materials. Nor can I upgrade my main hand weapon without some upper-star tier materials.

I tried melding some materia to my gear, but frequently encounter item stat caps that prevent me from gaining much from the materia ("the selected item's level is too low to maximize the materia's potential"). Heavensward crafting gear is also currently not available to me.

How were people able to bridge the gap between one-star and two-star crafts at level 50 in ARR?
