To feed or not to feed...

[SouthPark]

Could maybe think of out in the wild. Orchids can still gather nutrients when their flowers are open.

Also - for my own setup, I add fertiliser at the beginning of each month, and just guessing that the orchid roots can still actually get some fertiliser hanging in the media whenever the media gets wet. I then also apply mag-cal at the middle of each month. I have the option of applying both together though - but just purposely apply my fertiliser and mag-cal at different times.
