On the Blues Jam in B minor you have the opportunity to step out of the pentatonic box at :19 when it moves to the iv chord (E minor). Use the minor 6th of the B minor scale at this point (G), because that is a chord tone of the chord happening at that moment.

Also at :33 when it goes to the v chord (F# minor) use the 2nd of the B minor scale (C#). You still use the pentatonic minor box as a visual reference guide. But practice seeing, planning & using the diatonic minor notes inside & around the pentatonic box.

I cover this approach in depth in this tutorial on improvising in a minor key.
