Okay guys and gals. Quick question about mixing up some RY4. I mixed 30mg of TFA RY4 double at 12% flavor and 18mg strength. I steeped it and it sat in the cabinet and turned a nice orange color. It was so good I made a bigger batch. I always try to triple check my measurements but for some reason this batch is staying a light yellow color. The only difference is I went from 70%pg to a 50/50 mix. It's been sitting a month with no change in color. I'm afraid to try it in case I messed something up. Any insight from the pros? Thanks.
