CANNABOOST is specifically developed to give the best results in combination with an optimal fertilizer regime (for example with CANNA nutrients for flowering plants). Equally important to note is that CANNABOOST should be used with PK 13/14 as it supplies the extra levels of Phosphorous and Potassium a plant needs for optimal flower/ fruit development, over a limited and defined period of time. PK 13/14 should still be used when the first flowers appear inline with current feed schedules.
In general, it is not at all wise to mix fertilizer brands. CANNA fertilizers contain all the necessary nutrients a plant needs for optimal growth when used per the feed schedules. Other liquid fertilizers may have a destabilizing effect on the substrate and do not necessarily contain the optimum mix (ratio) of nutrients.
