I want to try to use epsom salt but I don't know how to use it. How many times should I use it and what dilution rate.

Thank you.

Hi bdelfiero,

discoloration of the leaves might be a natural process on some orchids like, dendrobiums where the leaves turn yellow then falls off or it can also be a sign of too much light. What kind of orchid do you have? Post some pics!
