Ok mate-I use bio biz all the time, and what I do is put half a teaspoon of bio grow into a 2 Litre bottle of water, use an empty coke bottle, this works out at just over a mL per litre of water. Because Bio Grow is an organic fertiliser and is made mostly of seaweed extract it is virtually impossible to overfertilise an organic grow. so don't worry at all about being exact, in fact I personally believe the plants actually respond a wee bit better to a wee bit more. as you can see in your chart use bio grow right through the grow from start to finish, but keep an eye on your plants and at the faintesthint of leaf yellowing feel free to double the amount of bio grow until the leaf yellowing subsides--note--once a leaf is yellowed it will not recover so adding more bio grow only has the effect of stopping any more leafs yellowing it will not cure the leafs that have already yellowed. when flowering starts and you are using bio grow and are also using bio bloom then just use the coke bottle method ( 2 litres in a measuring jug does the same job ) and add in the required bio grow, also the required amount of bio bloom and any other additives you might require at the time like Epsom salts to stop magnesium deficiency. hope this explains things a bit, its very easy once you get the hang of it. PS Ive also used a teaspoon of treacle ( molasses ) per 2litres , in addition of course to all the bio bizz for the last 3 weeks of flowering. Because its an organic grow there is no need to flush, although some feel better doing so----the reason you don't need to flush in an organic grow is that remember the organic mantra---DONT FEED THE PLANT, FEED THE SOIL the bio biz feeds the bacteria in the soil and the waste products of the bacteria feed the plant. its a really good system of ferts, and dosnt carry as much if any risk of overfertilizing. sorry this is a bit rambling but I'll keep an eye open here and if can be more helpful feel free to ask.
