Weezy90answered grow question 6y ago Okay, thanks for the update, that's handy!
I definitely wouldn't add anything for now; I looked up some extra information about the soil in which the seedling is planted.
I found this for you.
Ocean Forest is capable of frying seedlings to death and causing nutrient lockouts at the end due to a poor mix of nutrients and an overdose of nitrogen. Foxfarm has a seedling medium called Light Warrior.
So stick to just water for now and wait it out.
Cheers! 😊
