I'm still doing kits along with the AG,
For the kits
Campdon tablet for the cold water you'll be adding to the kit.
Swap out the kit yeast for 1 you like or know.
Mix the dry dme in the bottom of your fermentation bucket etc with boiled water and mix till the clumps have gone, pore the LME from the tin into this add more hot water to rince tin out, mix well, add cold water upto where kit says(should be in yeast pitching temp after this) pitch yeast.
The only other thing I do is adjust for the chloride sulphate ratio and I usually add 5g of calcium chloride to ballance the ratio
