Kush likes organics..either brew some guano teas or buy some bottled stuff..earth juice, roots organics. Just make sure you bubble them for 24-48 hours to stabilize PH...get a bucket, add water and nutes, put in air stone and wait.
That would be my suggestion...not sure on what method you had in mind.
Definetly organics in mind...i have the whole advanced nutrients organic line up and am using black gold coco mix soil...advanced nutes are very expensive im hoping to get the same results with something cheaper? i have been reading on here peeps use fox farm nutes and get amazing results...and some use the flora series...to use the flora series do you have to be doing hydro??
