THC vs. CBD a little disappointed in results

So I grew Runtz auto, and Grandaddy Purple autos this year. Just tested my buds at a local shop, who use the Purple Pro tester. This was my 3rd grow, and I use a handheld mocroscope to know when trichs are ready before harvesting. Dried out, and been curing for 3 weeks in grove bags. The smell and taste I thought were my best ever. However, when it tested, the Runtz came back at only 6% thc, and 8% cbd. The PG came back at only 13% thc. This was the first year I tried an AC Infinity bud cleaner, which definitely saved time. I like the high in both, but again very disappointed in thc levels. Don’t know if the bud cleaner took off a lot of the trichs, or just bad genetics on plants. This was the first year I wet trimmed also, don’t believe that would make much difference. What’s everyones thoughts?
