Those small lumps are scale, sucking pests which can be challenging to eradicate. These small pests gradually weaken the plant by sucking on vital plant juices.

I don't know what your plant is but it appears to need more light.

indoor hibicus???? .. well.. there are so many H.. i am sure there are houseplant versions ... but i cant ID on these pix ...

peeling them off is good enough.. if you can get them all ...

they hatched last spring... to be that size already ... ?????

your plant is incredibly stressed... you might try the NAME THAT PLANT FORUM to perfect the ID ... and follow thru to the next forum.. for info on how to grow it better.. to reduce stress ..

if that big plant is growing in that small cell pack... you can do better ...

thanks for your input! had no idea that's what scale looked like at that size...looks more like a viral/bacterial growth. gonna cut off most of the offending vines and break out the neem.

You'll never see the hibiscus bloom inside.

I'd examine all of your other plants for scale, spider mites, and other pests. By the way, there are many hundred of species of scale insects, each unique from the other.
