Canna PK 13/14 is a must-have for any gardener looking to take their harvests up a notch. It’s compatible with all systems, substrates, and non-organic nutrients – plus it contains premium mineral components that provide the extra phosphorous and potassium needed during flowering! For best results try using 1.5ml of this powerful booster per litre three weeks before harvest or you can use the ‘trickling’ method: begin adding 0.33 ml on week 2 or 3 of blooming cycle until time for final flush; your plants will benefit from having access to key bloom ingredients over an extended period leading to bigger & better yields! Keep in mind though not to mix other PK boosters at higher rates than recommended as too much is never good either – when combining different additives always separate add each one into feed water one by one stirring well between additions
