I'll be following your dry ferts progress with interest.
I've recently swapped from TPN to TNC. It's considerably cheaper but dry ferts are even more so.
Yeah without doubt, if you think about it, i got 1500grams of powders, 12 teaspoons create 1 litre of ferts, thats going to last me for two weeks per mix, for you, it would be one three weeks. ( I think im only 100 litres more than you)
There is probably enough there to last me, at a random guess, 9 months before i have to top any of them up. So yeah, hopefully the plants react well to it. No reason why they shouldnt really....!
