Sounds like your potted Lemon needs a good feed.
Try 'Yates Acticote Fruit, Citrus, Trees & Shrubs'. A special combination of advanced fertiliser technology that gives your plants an instant release of nutrients, then continues feeding for up to 12 months.(depending on temperature and soil moisture).
Supplement this during the growing season with some Yates Thrive Citrus & Fruit Liquid Plant Food weekly applied over the foliage and roots.
