Brassavola Nodosa (Remar x Mas Mejor') spike nub?

[Ashleyma23]

I bought this orchid the other day since the other members said it was a great addition to have.

I kept it in the same media (charcoal , bark , and perlite) since it didn't show signs of decay. I think I read somewhere they don't like repotting , I am not sure thou.

I placed in in my south window.

I couldn't find info on fertilizing or watering.

If anyone has additional information.
At first glance I thought I saw three spikes but they were new growths. Now I am aware of where the spikes grow from and there are two forming.

On the top bulb there is one spike nub if I'm correct? The other one I didn't not take a picture of.

What is the requirements for spikes?

Thank you.
