cal/mag deficiency? pics included this time

[WayBaked]

they're in flower with about 3 weeks left. the problem started during early flowering.

The darkening of the leaf tips leads to a different conclusion than spider mites.

edit: Checking my grow bible for you. Will update if I find relevant info.

Do you spray anything on your leaves?

This is during veg right?

What nutrients and soil? This could likely be toxicities not deficiencies.

Is it appearing on new leaves?

^ Important questions.

I know you sprayed Spinosad on your plants, but did this problem occur before or after spraying?

And have you sprayed anything else?

When did you spray the plants with Spinosad? And you showed pics of 2 leaves, but how widespread is the problem? Is it all over the plant, in the middle of the plant, bottom only, top only?

check roots for braod mites, you will need a scope

definitely a calcium issue, but you or these other pro's must figure out what it stems from. gl.
