aloe vera

Question

My plant was doing well but suddenly took a turn for the worse. Leaves almost look like chunks are in them.

Answer 1

This is likely Brown Scale.
As the insects grow they become fatter and may appear to be bumps in the leaves.
You can use a Q tip dipped in rubbing alcohol and wipe each insect away.
Spraying the plant with a insecticidal soap will also be effective.
