you're over-watering ... that's the classic 'look', anyway ... I gotta add, that I stopped using FF Ocean Forest after a couple tries, it was just too rich for my young ones, trashed them :wtf: ... older transplants did fine in it ... others have great luck with it, I suspect strain may make a difference, don't know for sure ... consider that, but watering is your main issue, make sure the plant goes thru 'dry' and 'wet' cycles ... the plant takes up nutrients as it is drying, and needs the oxygen to the roots, can't drown ... :thumbsup:
