hey guys, i have another problem...

the dendrobium that i got a few weeks ago had a few leaves yellow and fall out.

when i got the plant, it has about 5-6 canes. 2 of them have leaves. the smaller cane had 3 and the newest/biggest cane had 8 leaves. the problem started like last week when 2 of the 3 leaves yellowed and fell. it didnt dry out, it just yellowed and fell. 3 days ago, the 4th leaf from the bottom in the largest cane yellowed and a day after it dropped. and now the 5th leaf is starting to yellow.

is it normal for middle dendrobium leaves to fall out? the medium is coconut hust and charcoal in clay pot with holes. it is also as of the moment flowering, 3 are still buds. do i need to repot?

thank you guys!
