What you need is a stable nute regime, stable temps and humidity, and good air circulation. Egg shells will take forever to break down. They have to be composted. Epsone salt is fine but too much will cause even more problems.

Mine looked like this but not as bad, was my humidity was off and my transpiration was out of whack. Caused uptake of nutes to overfeed. Humidity change brought them back pretty quickly.
