Heres some info for you newer growers, to help identify problems your plants are having, as well as how to fix them.

Nitrogen deficiency: Older leaves will start to yellow and the plants growth will be stunted. The plant will appear to be a pale green.

To fix nitrogen deficiency, simply give your plant nitrogen. Worm castings is a good source of organic nitrogen for example.

Phosphorus deficiency: New leaves are small and weak, falling off the plant at times. Older leaves will begin to turn a bluish-green or bronze, and flowering will be delayed.

Phosphorus is mainly insoluble so it might take some time for it to penetrate the soil, and take effect if you do have a deficiency. Try using a super-phosphate or bone meal.

Potassium deficiency: With a potassium deficiency, older leaves will look like they have been scorched brown.

To fix this deficency you can use liquid seaweed products or sulphate of potash, which is a rich source of potassium that is completly soluble.
