About 3 weeks ago I purchased my first orchid on a whim, suspecting I'd end up killing him. But he's been growing happily, I've had 2 new flowers from him within that time! (I've recently learnt that I have green fingers :D) I haven't used anything other than water and Baby Bio to grow him.
A few days ago I noticed a new growth on him and I'm unsure what to do with it as I hadn't researched them much before my purchase.
I've attached a picture in hope of some advice, thank you!
