How can I check the values of two execs, and branch them as a condition

It’s probably better to have all the inputs in the same blueprint, like the PlayerController class, instead of having the input events directly on the bush. From there, you either grab a reference for the bush with GetAllActorsOfClass or GetAllActorsWithTag to set a bool variable in the bush.

On the bush itself, it’s just a question of setting the bools and proceed to the health decreasing code. As an alternative, you can also use a looping timer for the decreasing health
