Using fertilizer on home-made soilless potting mix
A few quick questions:
1. How to make seed starting and potting mix at home? 1/3 sphagnum peat moss, 1/3 perlite and 1/3 vermiculite? Just to be sure, I can use this combination to germinate seeds AND grow indoor plants, as long as I add nutrients later on?
2. Regarding nutrients, I've read that one must start adding diluted liquid fertilizer to the seedlings once they develop first pair of true leaves. Any further suggestions? Any alternative to using fertilizer?
3. Lastly, if I am using seed starting mix to germinate seeds, and then using potting mix to grow the seedlings after they develop first pair of true leaves, do I need to add fertilizer to this potting mix?
