Aptus AP20010 Peakboost 1L Phosphorus Booster, 1 Liter, Nutrient

Peakboost along with its sibling product finaleboost make up the Aptus Flower development and bulking solution. Perhaps the most noticeable implementation of the third pillar of Aptus philosophy: mineral antagonism, peakboost moves the vast majority of phosphorous used during the bloom cycle solely into one product.

With this formulation, Aptus has allowed for absolute control of heightened phosphorus application throughout the specific phases of a plant's growth cycle. The specific application of plant-available phosphorous allows for optimal health by removing the negative antagonistic effects of less effective commercial bulk products containing high amounts of both phosphorous and potassium.

With Aptus peakboost, you will see the DIFFERENCE in your final harvest by having optimal plant-available phosphorous with the elements usually antagonized away including: zinc, Iron and copper fully present. Directions for use: Use during weeks 2-6 during flowering at 6-16 ml per 5 gallons. Do not use during weeks 7 And 8 of flowering.

To stave off purple stems in veg, feed at 1 ml per gallon with the Aptus vegetative feeding chart If needed.
