I’ve started more seeds than I can count in ocean Forrest with good results. Switched over to happy frog a little while back for seeds because it’s a little lighter on the Nutes.
If you do start seeds in ocean Forrest don’t add Nutes for at least a month. I go from a solo cup into a 1 gallon to a 3 gallon and don’t add any liquid Nutes through out pretty much the entire grow. Just recharge and a top dress going into flower.
