Could This Be A Calcium Deficiency?

[Sponty]

Good afternoon.

Could anyone please confirm this is a calcium deficiency please? I've given the plant a folair spray to try and help but don't want to up the Cal-Mag in the next re-charge if it isn't that.

All the best!

Please take plant out of tent and take pictures in normal light so we can see well.

Hopefully these are a bit better. The tips are beginning to curl now also.
