Calcium def.

Am i right the start of calcium def. With these twisted leaves. But this could be over watered too though right?

I don't see Ca def. I have seen my leaves do strange things (like roll over) prior to showing an Mg def. I've never known if that's related or just coincidence from heat, dry air, too much fan blowing.

A couple of people have said buckling, twisting leaves are pH problems. My soil is perfect 6.5 and I'm getting it. (My humidity is about 20-23%. So, I'm still thinking that's what it is.).

Looks green..
