Charts, snake oils.....and another one bites the.....uh......'dust'.
You wanted expert advice, Uncle Ben is about as expert as you get, and i think what he is saying is, why would you go off a chart 'predicting' what your plant will require, when you could just learn to read your plant, and give it what it actualy needs
scrap the chart m8, and some of the advice given here, WAY too many boosters and shit, find a decent N-P-K for your stage of growth, dont just throw all them 'brand's at them cause the bottle says it works, read some of uncle ben's stickies, there is shitloads of very useful info held within them, from years of expierience.
