Ive looked at every bloom booster on the market & most are a complete waste of cash , especially shit like pineapple , grape ect ect , the npk ratios are what tell the story , ive tried several boosters that came as freebies when i load up on GH Bloom & Micro & the only bloom booster ive found that gives real results is Botanicare brand Hydroplex , it's npk of 0-10-6 which is perfect for budding & it also contains an assload of micro nutes such as Calcium , Magniseum , Sulfur , Iron , Cheleated Iron , Maganese , Cheleated Maganese , Molybdenum MO , Zinc & Cheleated Zinc , you will not ever experience micro nute deficiencies running Hydroplex .
At my high point i had 8 seperate 4ft x 8ft flood n drain tables going so it was easy to do side by side comparisons running different bloom enhancers at the same time in different tables while keeping 1 table fed with the General Hydroponics 3 part system for a baseline , the only brand that gave reliable results of larger yeilds was Hydroplex , i added 10% to 15% & retained those numbers to this day by using Hydroplex 50/50 with GH Flora Bloom , the GH Kool Bloom & Advanced shit added nothing except ppm .
You might want to forget about using that Clearxex crap too , flushing with it didnt make my buds any smoother , infact your working against heavy yeilds by flushing instead of feeding , the last 7 to 10 days the buds are still bulking up & you loose that when you stop feeding , your best to cut the Nitrogen by week 4 vs flushing ,
