its best to use that big bud early and throughout the bud stage i think, i havent resently looked at its schedual online but i beleave its a bloom stimulator heavy in k and p. i wourked guano evely to the entier pot then gently scratched to work it in a bit befor watering, like gentle pokes just to break the top crusta bit. the roots grow throught the pot and only consentrate in the middle but i havent used guano in some time, i dont know how much your super swell is but i used earth juice bloom as guano substitute -the guano i was useing was for hydroponics and soil this new stuff is 2 kinds of gunao and alot more goods

i call my solution biojuice. anyhow if youve been giveing it a mix of eguana juice grow and bloom shifting the ratio more and more to bloom is best -probly more in line w/its schedual.
your results are good this far soo dont take me too seriously

, i never just water my plants they allways get even a weak solution but in flower ive given them high doses and feed every time. according to the directions on each bottle though, i havent burnt w/bio bizz yet or earth juice -the max ive given was 2tbs combined npk nutrent per 1.5gallon pump/can plus a bit of top max and bio-kelp(alg-a-mic), ive also blended 1.5tsp earthjuice grow 1.5 tsp earth juice bloom for flower .the only grow i add in bloom is bio juice cause their more of a k>n ratio and my plants just love this molasses nutrient bio-grow. still more tweeking like now im useing more bio bloom in vegg instead of useing as much ej ferts.
i mean if you only add the big bud powder befor you flush your not getting the full potanchel of the fert throughout bud set and bloom, its important they still have nutrient while flushing but theirs ample nutrient left in the soil and stored in the plants leafs. ive been useing down to earth soluble root stimulator (40%humic acid, endo and ecto root fungi) this is intented to stoke nutrient cycleing and hopefully better flush the soil while keeping the plant as healthy as could be.
humic acid is like a vehicle for nutrients in move between soil particles -fulvic acid i think acts in side the plant much in the same way to help nutrient cycleing and other stuff but its the cheep humic acid im interested in -i was reading about top max that it may have fulvic acid but id have to e-mail the company to find out for sure.
