Ok Yesterday she was doing well I touched the top too see if I could cut it but I didn't, so this morning I notice the top was getting brown and I don't know if I should top it off so it wouldn't effect the lower half

Anytime you touch the flower it will burst the sacs and also bruise the flower as shown here.
