Leaves Twisting: Should I Worry?

Should I be worried about the curling of the new growth? She's a 4.5 week-old NL+autoflower that started pre-flower last week, and has been given 3 tsp/gal Big Bloom + 2 tsp/gal Grow Big @ pH 5.5 twice a week lately. The leaves started to twist around just this week.

Too much N, 1/2 the big bloom.
Why does every auto i look at have these mutated, strangled looking phenos?
Stay away from ruderelis crosses mate, nothing good comes of it.

Those are broadmites for shure I've grown some autos never done that. I've also had plants infested with broadmites thats the type of damage those little fuckers do!

I hope it's not mites! I examined a few leaves under a 60x lens and didn't see any bugs.

Flushed it with 2 gal of pH'd water and will cut back on the N.
