I would have to agree give it more light , I would also grab some cal mag, and or superthrive. but like hotrod said no nutes will be needed for 3 weeks or so, my favorite method for this strain in Fox Farm Ocean forest and lots of sunlight, and I have seen great results with this method and next to no nutes added aside from occasional Epsom salt and molasses every other watering. After seedlings take off transplant them into a large pot I would say you could get away with 3 gallons of soil per but if you really want to see a great plant go with no less than 5 and if you want a legendary plant no less than 10. I would go ahead and get some neem oil organic pesticide as well as from what I have seen this strain is somewhat fickle as the beginning of its life cycle and can fall prey to disease and bugs pretty quick, don't be worried though it turns around to be one of the most forgiving strains for a beginner.
