Another good one for a budget, GH Floralicious Plus. This 16oz bottle will make 470 gallons of hydro reservoir or soil drench at 1 ml/gal or around a hundred gallons of foliar spray at four times that strength. It’s vegan and contains NPK, kelp for micros and hormones, humics, and aminos. You could use decent potting soil, this, and a PK booster and you’d be good to grow.
“Floralicious Plus has high concentrations of vitamins, complex sugars, amino acids, phytostimulants, polyflavonoids and aromatic oils in an organic fluvic base. Florolicious Plus also contains a liquid suspension of Bacillus Subtilis.”
