i have tried many different methods with various results over the years, i settled with cocco which you can buy from your local hardware and is cheap $3 for 19 ltrs expand and wash well, ph adjust a bucket of water and flush with that last 5.5-5.8 should be fine. water for one minute every 2 hours or until you get between 10%-20% waste, then ph test your waste it should be roughly be 6.2-6.4 you can test salt as well this gives you an indication of what your plant is drinking. this method is fool proof once you get the hang of it, and you only have to check it once a week. use a cocco specific nute i use nafarious which is made in oz and is under $25 for both a&b. some kush strains can look odd when in the grow stage some have big wide singe leaves resembling small banana leaves, but flowering is awsome most kush strains produce huge trichomes... i have grown with cfls only use them for cuttings i use 400hps and 90watt ufo led together with awsome results, i last year pulled 9 oz of bubba kush 1 plant in small cupboaou rd grow yeh by the way most kush turns really fast once you induce flowering, anyway good luck any more questions ill help what i can!!!!
