Put it in John Innes No 3 loam based compost and I would think that would have enough nutrients in it for this summer.
It's probably a Norwegian Spruce (they're the ones more frequently sold in pots, unless someone knows that Lidl were selling something different?) - it will need good light but if it's in a pot it won't be happy if it gets hot and dry, so I think I'd give it full sun in spring and autumn but move it into a more shady spot in the mid summer, and if we have a very dry spell I'd give the foliage regular sprays with a hose as well as plenty of water for the pot.
They can grow up to 3 ft per year in optimal conditions, but I imagine that in a pot the growth will be slower - you'll have to let us know
