Justin discusses taking a minor pentatonic / major pentatonic approach to blues in this lesson: https://www.justinguitar.com/guitar-lessons/mixing-major-minor-pentatonics-bl-804
If you have not used major pentatonic in blues previously, the three lessons that precede that one are essential too.
Also, in the live session, Justin mentioned using the ‘6’ and / or the ‘9’ notes. I seem to recall that he name checked Robben Ford as an example someone who incorporates these ‘other notes’ to the basic minor pentatonic.
Many years ago, on the old website, Justin had a short series called Blues - The Dorian Approach. They no longer appear on the new website but are still available on Youtube. He shows where those extra notes appear in the five pentatonic patterns with examples.
