I personally would only use that as a flower booster,so would only use some thing like that at week 5 for one feed, makes them go into over drive,though I don't use that I use house n gardens shooting powder,which is the same kind of thing,as I say they say only to use it for week 5,makes the plant think the end of its life is coming so starts putting weight on
well unless you make teas yourself nothing is 100% organic,I personally grow what I call bio/organic weed.After all if growing indoors you can only replicate outside to a certain extent and even if using organics indoors as you arent using the sun to me it is just bio buds.
Personally I use a range by house and garden, Bio component 1 part,along side their multi enzyme (super concentrated with cannas you use 2.5 ml with this is one ml a liter)and their root accelerator plus their pk 13/14 which I use for one feed as its only for week 5 and I only feed once a week on sunday to keep it simple,then there is bud xl which I use through out budding,you will find house n garden is quite expensive,BUT- it is double concentrated so goes further,and unlike a lot of nutrient makers,the guy that owns this is actually a gardener,and owns a nursery etc,so its not just about making a product to sell,he also uses them himself,which says alot
