New Phal for the home (black spot)

[milan360]

Hi Ladies and Gentlemen,

So I couldn't resist but get myself my third orchid (1st phal died, 2nd dendro doing well sprouting a new cane) which is a nice huge and beautiful Phalaenopsis with white blooms.

I was a bit hesitant given the fact I was a total noob(and still am) at taking care of orchids and let the first one die.

However, I did a careful check on the roots and leaves with this new one (plenty of fleshy green ones with 1 or 2 rotten roots. Leaves look OK to me . Nothing unusual)

I got it from Ikea as with most retailers they just squash them in sphag and a plastic pot. Some questions:

1) I know I have to repot it in charcoal (where I live humidity is high and charcoal seems to be the recommended medium), it's in bloom any issue with replanting it now?

2) The crown looks fine to me except for a small black spot at the base (attached picture) anyone able to assist?

3) Any tips other that the above which I can receive before I repot? I foresee balancing the plant might be an issue as it's huge and the spike it held by 2 metal canes clipped to it. The pot I'm gonna use is a plastic pot with holes below. Couldn't find clear pots.

Thank you and best regards,
