Ill try to throw down my two pence on this one.
First, you should have the seedling in 100%light warrior(1"widex2.5"deep), just so it can develop good roots, the rest ocean forest.
Then try to get your humidity low as possible for veg.(Higher humidy is to get the seed to sprout and for flowering)
For soil you need to maintain a pH of 6.2-6.8.
