Buy new soil then research? Kinda backwards but seed starting soils can have different effects on different plants. for some plants it may be feeding it too much and sometimes too little. It may cause a nute burn which is very bad for seedlings but maybe not. I dont think they would make it that hot if its for starting seeds. It should be good soil just watch for signs of too little or too much nutes. Also read bag carefully to see what the soil contains. Good Luck!
