I pitched this last Sunday. Airlock activity stopped on Tuesday and checking the SG today I found there is still a thick krausen. Reading was 1.02. On rechecking the pouch I think I've dropped one - says extra fermentables are 1.2Kg LME then directly under, 1Kg dextrose then it says OR 1.4Kg beer enhancer. I added 1Kg dextrose as well as the LME. Should it have been the LME or the dextrose or the beer enhancer? I stupidly didn't take the OG. If I've got this wrong have I ruined the brew? Any advice what to do?
