This is a relatively common occurrence, and it's a very easy fix! You can just write "first time only" or "second time only," depending on the situation. For clarity, I'd write "both times" by the final three articulations (if I understood you correctly).
Note that this could also be done with a first and second ending situation, but for something this simple "first time only" is sufficient.
On another note, I'd recommend adjusting the rests in the first measure of the drums; it looks a little unnatural. I recommend you follow the eighth note with an eighth rest, quarter rest, and then a half rest since it shows the beat subdivisions more clearly.
Edit: Here's an example using first and second endings. I don't know exactly what comes before or after your example, so your situation might differ, but this is the general template.
