yeah the chart dosn't show the first few weeks of vegging, but the instruction there is 1mL per litre of Biogrow every time you water, and that's right through till the end when obviously you stop for flushing. I think the reason the chart is a bit vague on this point is that many folk veg for different lengths of time, some folk give them a full maybe 50 days, and others if growing from clones will maybe only veg for 2 or 3 weeks and keep the plants small, anyway, Ive been using this regime on my grow just now and all is happy in the garden. 1ml is a fifth of a teaspoon and what I do is get a 2 litre coke bottle and then use those little spoon things you use for adding a certain amount of spices etc when cooking, I choose the half teaspoon one and add that amount of biogrow to the 2 litres of water in the coke bottle, give it a good shake to mix it up and its ready to water with.
