Peristeria spike or new growth

[adritakar]

Hello। This is adrita from West bengal, india। Recently I came across this peristeria on an online orchid nursery and bought it। It has been in my care since 2 months। It is beginning to grow a ton of new growths with the advent of our monsoon season, but there is one particular nubbin who has confused me whether it's a growth or a spike! Can you help me to identify it?Some tips regarding culture would be welcome too।
