coconut water mate, try that, also if you live near a nice clean beach, you might want to try sea water 1:30 mixed with fresh clean water.
Also if you live near palm trees, you could always ask if people burn these, collect the ash and use this at about 50g/5L thats about 2TSP to 1.5Gallons approx.
most bloom enhancers are bollocks, excuse my language. Most flavor is destroyed by over watering very young plants. however, it is possible to stimulate some plant defense system in order to boost both sugar and minerals/ vitamins related that dont involve hydro stores.
I speak as a man that makes nutrients for sale. I dont make a bloom enhancer, but I do have products that stimulate ISR SA and JA and so systemic repsonses therein, such as increased trichome density and terps or other essential oil etc.
