Crystal White Kush on Coco 12/12 from seed

So I am planning my next round.... This time my first single strain diary. I received 15 seeds from Super Sativa Seed Club to make this happen. Nice packaging, not my first SSSC strain (currently growing Lava Freeze). Since it is a single strain I am going to try to make it a low maintenance round. 12/12 from seed, single nutrient (allright and a bit of CalMag) and Blumat drip-system. Next Friday I will put them to germinate as soon as I have my newly ordered nutrient. Please give me some tips for the nutrient (locally available The Netherlands), not separate bottles for grow and bloom, must be able to keep fresh for 2/3 weeks in container (with circulation) and preferably no need for boosters or anything.
