Chech the bottom of the leaves for spider mite, use a magnifier or a loop they(mite) are tiny but mighty.

You've got a problem.
Fert burn or deficiency, pH, and heat are all likely culprits... pics and a description of what you're doing would help LOADS.
Mite damage to the point of defoliation would be pretty obvious; look for white speckles like overspray on the surface of the upper leaves.
