Tissue cultured explant developing black edges on leaves

[Vidyut]

So, the angle of the sun has changed and it seems one of the truncatas fresh out of TC caught direct sunlight briefly before I woke up. Luckily with the fogger and misting, it isn't dead, but the edges of the leaves have gone dead(?)

Any idea how to help it recover? Not sure what to expect. Does the damaged area remain as it is or recover (looks deadish). Does it spread? Anything I can do to help it? The green part looks healthy. No wilting or anything so far.

It is dark right now. I will post photos in the morning.

The blackened material will stay that way. It won't recover or become green again. However, it won't spread if its conditions going foreward are good, which it sounds like you're doing. That's all there is to do. Keep on hardening off your fresh plants until they are able to take that sun.
