sorry, i don't own a camera at the moment. the white spots are on top of new growth and are not on the lower leaves. from the top they are white from the bottom transparent. the bumps are on new larger leaves. the bottom of the plant has suffered from magnesium deficiency so those leaves are falling but the plant is growing fast and not suffering anything in general.
Look where the stem meets the leaves and see if there is any webbing, that's usually where it starts. Also check the undersides of leaves for any webbing also.
no, it doesn't resemble this, the Spots are smaller, evenly spaced on the newer leaves and transparent from the bottom, the newer leaves are forming on new colas.
The bigger leaves, below the new colas, that are bumpy are drying out slowly, more like a magnesium deficiency and damage from recent flushing.
I guess there is some root damage... I'll treat the leaves with soap / neem oil.
