I was double checking my numbers and noticed that the online calculator says/is using the following ratio for Veg Formula 2: "MIX 8ml (1.62 tsp) Thrive Alive B1 Red" for one gallon while the online pdf of the recipe for succes and the hardcopy I have both say 11.35ml/gal for veg formula number 2. Which number is correct? Thanks for this valuble online resource.

Just checked the metric pdf and it appears to be using 2ml/L (7.57/gal) value making me think this is the correct number.

Saxman,
As much as possible, work off the original metric values. So in this case using the 2ml/l (or 7.57/g) value will be just fine.
The online calculator using a slightly higher imperial conversion value will reduce as one inputs a larger reservoir size into the equation.
Using your example, when inputting 1G into the calculator it tells you to use 11.35ml/g; but when inputting 3g, it tells you to use 23ml TOTAL which is much closer to the 7.57 value previously stated. (7.57 X 3 = 22.71)
It would be great if the world used one system of measurement.
Thank you for your continued support.
