Indoor Hey AFN - Calcium or spider mites?

[cowboy]

Whats the deal. Calcium or spider mites. I do use sm90 and b1 tonic for foliar spray. I use no cal mag.

Jungle juice a and b ec 1.2
voodoo juice b52 tarantula piranha rapid start sm 90
ph 5.9
OG Kush S1 from reserve privada . 37 days old.

Old growth affected. Maybe two leaves.
Upper growth is lush and green. Slightly weak stems, (Lanky OG pheno maybe )))
Other lower leaves are like this. It was a mutant. Lower growth is a bit f'ed
Well that's the mutant old lower leaves.

Any help would be greatly appreciated

The tips of your leave are crispy right? That indicates a Ca/Mg def.
