What fertilizer should I use for transplants?
If, after all possible precautions, your transplants are stressed due to nutrient-deficient media, you may need to use supplemental fertilizers such as fish emulsion. Organic sources of supplemental fertilizer include fish emulsion, soluble fish powder, kelp extracts, worm casting or compost tea, or other OMRI-approved products; see Using Organic Nutrient Sources (Sanchez and Richard 2009). These fertilizers can be applied to the soil by fertigation or foliar spray. Be careful with supplemental fertility. If you produce transplants in an area that is later used for in-ground production, leached fish emulsion or other products can build up soil nutrients to levels exceeding crop needs.
Why is compost good for seedlings?
Compost adds organic matter to the mix and supports diverse microbial populations that can suppress soilborne-disease causing organism s (Klein and Hammer 2006). Microbes break down organic material, releasing plant-available nutrients that are slowly available for your seedlings.
How to know if compost is ready?
If you use compost, make sure you are using high-quality compost at the right stage of maturity. Unfinished compost may release volatile organic acids that can negatively affect seedling growth and development (Grubinger 1999). One classic method of evaluating compost readiness is by smell. Finished compost has a sweet smell. Anaerobic, sour, or putrid smells are suspicious. If your nose detects an off smell, turn the pile and let it heat again before you consider using it in a mix (Klein and Hammer 2006).
How to test your mix?
To test your mix, send it to a reputable lab for greenhouse testing. Remember, this is different from a soil test.

Can you mix these different medias together?
Some growers do, depending on their setup. The mixes vary on how much a certain carnivorous plant needs. Taking into consideration what each media option can give, you can experiment yourself: do you need more moisture? Try to incorporate sphagnum. Do you need a drier, more draining mix? Stick with coco peat, or even add rocky, non-absorbent amendments like silica sand, perlite, pumice, and other chunky media options (as long as they’re all thoroughly rinsed).

Silica sand is sometimes used for drosera/sundews (mixed with coco peat) or pinguiculas/butterworts (mixed with other rocky media like perlite, akadama and coco peat).
Why do carnivorous plants grow in nutrient-poor media?
This is how they became carnivorous in the first place; they evolved to take their nutrition from sun and bugs. Their natural environment is usually very wet and frequent rain or running bodies of water constantly wash nutrients away while keeping their media loose. Because of this e volution, minerals and stronger fertilizers will burn their roots, which are only meant to take in water and provide anchorage.
