Something is Not Right

This image was taken at night as it best shows the yellowing issue with the leaves. Originally this was thought to be a sulfur deficiency which is commonly seen in colder soils, but even after adding Epsom Salts the issue persisted. Turns out the soil heating cable thermostat had failed causing the soil temperature to reach 91F! So, this is likely the result of heat stress on the roots.

An external thermostat has been added and is working out great so while this may look bad now, these leaves will likely later be removed anyway. Since the problem was caught relatively early the overall negative impacts on the plant will hopefully be minimal.
