Just when you thought it was safe to get back into the waters – You may want to think twice about ordering this product. Even though you can still find it on the market from second party vendors, ADVANCED NUTRIENTS themselves no longer list this a current product. As such, the information available about it is also somewhat limited and is now dated. The product was designed as a super-concentrated P-K bloom product in a (9-18) ratio which ADVANCED NUTRIENTS’ team determined to be the exact amount of potassium and phosphorus needed to boost blooms without root burn and binding. This was determined after initial testing failures using a (13-14) ratio that proved too hot. Given the edginess involved here and the fact that this product has been discontinued, we’d recommend adopting less risky, lower impact measures for better blooms.
