Whats causing this weird Leaf texture (hd pics)

Odd bumps on the new growth on 3 blue dream's in dwc. its a 6 plant bucket and the other 3, not blue dream plants are growing along just fine. Please RIU lend a hand.

Maybe a mag deficiency? Hard to tell with purple led light...does it look like rusty spots? R u using any cal mag?

I cant see it well form the lighting . but mabe this will help you http://www.420magazine.com/forums/problems-pests-disease-control/81275-cannabis-plant-pest-problem-solver-pictorial.html

please look at the bumps on the leaves not the color of them. Yes, they system has cal mag, AN 3 par, beneficial's, and 5.8 ph

Usually that'd be a sign of PH being off, but since you say its steady 5.8, I'd check the underneaths of the leaves for possible insects. Do you have a good meter? If you're using the drops/tabs, your ph may be off.

Have u calibrated ur ur ph pen if u havent done it in a while u might wanna do that be for jumping to a def most times all that is wrong is ph is out if its out it could be locking out nutes which might look like a def correct me if am wrong but ive seen ppl that have added nutes and burned them thinking the were under fed when.it was ph was off

I see the bumps and odd texture. It does look very abnormal. I would guess that it is a genetic trait or a genetic reaction. Possible immobile elements in excess and your leaves over hydrating and thinning due to dry atmosphere. Dial back every thing, flush the media with ph water then give fresh nutes and calmag with some B1 to boost some immune response, raise the lights and let them chill out a bit.
