Aptus Super-PK is a powerful bloom booster that should be used from early in the flowering phase until 2 weeks before harvest. The formula for Super-PK contains an optimised blend of 20% Phosphorus (P) and 25% Potassium (K), along with amino acids and vitamins that plants require to stimulate and push fruits and flowers to their optimum for a bumper crop. It’s also super concentrated, meaning only a small amount is required in your feeding regime allowing just 1 bottle to go a long way. And although it’s been developed to be used in hydroponic systems, it can also be used in coco and soil growing methods.

DIRECTIONS OF USE: 2.5 – 5ml per 10L (0.25 0 0.5ml per litre) during early to late flowering.
