My colleague's orchid is looking very, very poorly. I rescued it initially as it wasn't receiving sufficient sunlight, then during the recent heatwave my colleague neglected to move it further away from the window and as a result the poor thing got pretty bad leaf burn. I've now relocated it again to a spot where it gets plenty of indirect sunlight but it is not recovering very well.
I've also noticed some tiny white spots on one of the leaves, and the stem seems to have died off where my colleague tried to prune it back to encourage new growth. Can anyone please help me save this orchid??
