Uneven leaves
A lack of leaf growth and uneven leaves are signs of an aphid attack (below). Check tips of shoots and buds for insects, and treat with a suitable insecticide.
Red spider mites
If the room is warm and the air dry, you may get an attack of red spider mites. Mist your plant frequently to discourage them and, if the attack is serious, use a suitable insecticide.
Bud drop
This occurs if there is a lack of light or your plant is too dry. Water it regularly and place it in a light position.
