decided on hammerhead pk 9/18, will post the results in about 9 weeks

erm plants have been flowering 1 week thou, should that matter?

A lot of gardeners spend serious moola on phosphorus-potassium bloom booster products, but are they getting their moneyâ??s worth?
If theyâ??re buying Advanced Nutrients Hammerhead PK 9-18, theyâ??re getting more than their moneyâ??s worth. Theyâ??re getting the only P-K formula with the ratio of phosphorus and potassium that results in bigger buds and harvests.
Most of us know we can earn bigger profits growing more and better flowers if we apply special ingredients during a plantâ??s bloom phase.
Problem is, with so many bloom boosters on the market, itâ??s hard to know which ones work and which ones are just a waste of time and cash. When we heard our competitors were making boosters featuring high doses of Phosphorus(P) and Potassium (K), we wanted to know if these dose ratios helped make bigger and better flowers. They didnâ??t.

In fact, testing showed that their 13-14 ratios actually reduced bloom weight, size and quality. Worse yet, their products helped create ideal conditions for growth of one of the plant diseases you most hate to see: gray mold.

Our scientists are chronically dedicated to giving you the best harvests, so they figured out that hydroponics plants you grow need large amounts of K, not large amounts of P.

Only with correct ratios of K and P found in Hammerhead will your plants produce the impressive harvests you seek without providing fuel for gray molds that can destroy a harvest overnight.

Hammerhead PK 9/18 is the worldâ??s best potassium-phosphorus booster formula. It feeds specially blended, superior-sourced nutrients in just the right ratio so your plants absorb what they need to make the best fruits and blooms.
PK 9/18 lessens incidence of gray mold and other pathogenic attackers that eat crops in late harvest cycle. Other products contain the wrong ratios of potassium and phosphorus that actually reduce yield and cause disease conditions.

When you use our Hammerhead PK 9/18, you get the correct ratio of P and K, from superior source materials, guaranteed to increase harvest size and quality more than any other potassium-phosphorus product, or your money back.
