Issue With Leaves?

[FarmerNick]

I have two devils tounge plants that have these white bumps along the veins on the underside of the leaves. Ive only seen it on the Devils Tounges and not any other of my plants. I started them from seed, they seem to be growing just fine other wise. Some pics..

Anyone have any idea what this may be?

Its edema, cut down on the watering a bit and avoid watering when it's humid. Check out the topic I posted on edema
