White widow feminized. Starter soil questions

A friend of mine purchased White Widow feminized seeds. He has already bought Fox Farm Ocean Forest to start the seeds, but he has come to realise that White Widow is a sensitive strain, and Ocean Forest may burn the seedlings. Should he start the seeds in Happy Frog or Light Warrior? And when would a good time to transplant to FFOF be? Thank you

bump, anybody got any tips?

grew the same strain in the same soil many times. ocean forest has enough natural nutrients in it for about a month of growth but its not enough to burn a seedling.

Just to be safe, is my friend okay to start it in light warrior?

It's common knowledge Ocean Forest burns the hell out of seedlings. Use Happy Frog, then transplant to Ocean Forest. Light Warrior is soiless it has no nutes so unless you mix in other soil or use liquid nutes, it's useless.
