Ocean Forest is pretty hot for new plants. If you started them directly into that medium then likely you are over nitrogen. I start mine in solo cups with Happy Frog. Then within two weeks I transfer to a mix of 25% Happy Frog, 25% Worm Casting, 25% Peralite and 25% Ocean Forest.
By the time the plant can handle the extra nutrients at week two, then they go into that mix. From seed it is just too much for them.
Hopefully this helps.
