Plants growing in soil can be fertilised with any of the plant "foods" on the market. Follow the directions on the packet but do not overdo it. If you feed too often or with too strong a solution, you can cause overfeeding. The soil will hold the excess fertilizer salts and this will tend to build up with each application. Avoid this by watering with plain water several times between each "feed".
If you wish to use a hydroponics solution with soil, we would suggest a single pack solution such as Formulex. This is a full featured solution but is slightly less concentrated than the twin or triple packs. It is pH stabilised and will produce great results with soil.
It is also possible to use twin or triple packs with soil. The important thing to remember, whichever solution you use is not to overfeed. Nutrient solutions should always be applied to soil at half strength and no more than once a week. Watch out for the symptoms of overfeeding which are very easy to see. The leaves will have a tendancy to curl downwards and become dark green, brittle and glossy. If this happens, flush the soil by watering heavily with tap water. Wait a week or two before resuming the feeding routine.
