  We present an atmospheric retrieval analysis on a set of young, cloudy, red
L-dwarfs -- CWISER J124332.12+600126.2 and WISEP J004701.06+680352.1 -- using
the \textit{Brewster} retrieval framework. We also present the first elemental
abundance measurements of the young K-dwarf (K0) host star, BD+60 1417 using
high resolution~(R = 50,000) spectra taken with PEPSI/LBT. In the complex
cloudy L-dwarf regime the emergence of condensate cloud species complicates
retrieval analysis when only near-infrared data is available. We find that for
both L dwarfs in this work, despite testing three different thermal profile
parameterizations we are unable to constrain reliable abundance measurements
and thus the C/O ratio. While we can not conclude what the abundances are, we
can conclude that the data strongly favor a cloud model over a cloudless model.
We note that the difficulty in retrieval constraints persists regardless of the
signal to noise of the data examined (S/N $\sim$ 10 for CWISER
J124332.12+600126.2 and~40 for WISEP J004701.06+680352.1). The results
presented in this work provide valuable lessons about retrieving young,
low-surface gravity, cloudy L-dwarfs. This work provides continued evidence of
missing information in models and the crucial need for JWST to guide and inform
retrieval analysis in this regime.
