Working with a soil-less mix is considered slight more tricky then growing in soil its self. Nutrients will have to bed fed constantly through out the plants life.

Growing seedlings in a soil-less mix means nutes have to be applied, unlike a good high quality soil that contains enough food for roughly 3 weeks. which is great as its easy to kill off seedlings with excess feeding.

Nutrients generally change the ph of your medium. Use a ph meter after uv added nuts to water and adjust with ph up or down (an inexpensive ph adjusting solution.)
