I'm running full nutes now and have the gals under a 600 watt HPS....a few pics on mixing the nutes
The Lucas formula says 7 grams per US gallon (3.89 litres) but I use gun powder scales which are in grains (107.4 grains = 7 grams)
So since I'm only mixing 1 litre, I use 27 grains of nutes per litre....or approx a heaping 1 ml spoon full

Then I use a Pace Picante jar with about a cup of hot water, add nutes then use a milk frothier to mix (I can leave it in the jar mixing while preparing the next step)

Then I fill the mason jar 3/4 full of cold water and add about 1 ml of Cal-Mag

Then add pH up....I use about 0.5 ml...then add another drop or two if required

Then test the pH using GH drops....add more pH+ if require
