First DWC - Auto Blackberry

So this is my first hydroponic and I know nothing about nutrients so I chose Remo's full kit because it's not cheap in my country so must be good, right? The only extra i'll use is RapidStart GH and VegaMicrobes FatCrystal. The Auto Blackberry Kush was chosen because It's the most Indica strain of DutchPassion, with a high THC concentration, XL height (perfect for topping 4ºnode) and the winter of my country will be great to grow it.
