Hello everyone, firstly I'd like to say that growing D. regia from seed is a, sadly, misunderstood subject. Many have come to the conclusion that D. regia seedlings will die unless they are "fertilized" and a few early growers of the seed reported success using "osmocote pellets".
These days, I have not yet come across a grower who is able to corroborate the claims that D. regia seedlings "need" fertilization, particularly soil fertilization.
D. regia seeds are quite large and contain quite a bit of energy, upon germination the humidity should be decreased significantly after the first carnivorous leaves are visible (i.e. opening the bag or moving the seedlings) to prevent damping off.
If the seedlings are provided with a high amount of light they should be fine growing in conditions with a lot of water up to and above 3/4ths of the pot can be submerged, though as they age they will appreciate drier and drier conditions as they mature, particularly when they start holding onto, say, 5-6 leaves.
If the seedlings are mature enough, a foliar spray is greatly appreciated; however, the little D. regia will equally appreciate a small meal on one leaf. If you do foliarly fertilize, you will inevitably spray the soil and consequently you'll have to flush the soil out, and preferably the tray should be cleaned periodically as well. Because the soil needs to be flushed out I find that feeding the leaves is a simpler and safer approach.
