hi there
plz ganja sarah lousie or anyone who really knows help me out!
my reseller gave me hesi pk12/13 cause the same product from canna was out and he told me ita the same..but at home I notice that hesi hasnt the same description how to use it as canna....so hesi I can upload an image that tells everything
first difference I saw that this one is just for cocos and soil so I contacted the reseller and asked cause this may possible to grow with soil...so he said this should be no problem so I should use this too for soil,is this right or wrong?he said just the phosphor plus which is only for soil should not be used for hydro and coco thats why he has that not in his shop cause hesi pk12/13 can be used in every growing medium
 
second difference is that canna says that its only be used the last 3 weeks and hesi tolds that on image which is real different,so again whats the thruth?
hows about combining these with topmax from biobizz?I read in another forum when used top maxx these pk12/13 is nit neccessary...I dont know just used top maxx for outdoors and bio indoor growing combining with bio sevia from ghe
thx for answers

I can't really answer your questions Snoopy as I don't have experience with nutrient formulas other than Canna range, but I expect the PK 13/14 can be used interchangeably.

The truth is, depending on what sort of nutrient schedule you are using, you can use PK 13/14 in different ways. Some schedules use small amounts of PK 13/14 to raise the PK slightly throughout flowering (eg hesi), others use larger quantities for short periods of time as a flowering boost (eg canna).

Sorry I can say anything more definitive.

what forum was this on? thats a load of rubbish im afraid. top max isnt a p/k booster, its a bloom stimulator and should be used with a p/k booster. the npk of the top max is only 0.1/0.01/0.1
its wise to remember that not all strains will need a p/k booster, some will be happy enough with the p/k in the bloom nute.
 
another bit of advise would be to not even bother with either of the 2 products mentioned, the 13-14 phosphorus/potassium ratio is based on field crop agricultural research thats many decades old and totally inappropriate for growing indoor mj crops.
well thats what i heard anyway, lol.

most nutrient solutions will lower ph, i cant see how they can say it lowers it to 6.5-7.0, surely it would depend on your starting ph, and how much you put in, as to what it will be lowered to.
them nutes you mention dont seem to show any potassium(K) in them.
 
but, if you dont believe me snoopy, wait around for someone from sensi to come and answer you, lol.

kaliumoxid = potassium (k2o)

Apart from that, I agree with Barty... personally I have no idea whether the nutrient mix is suitable... don't even think I remember the maths to convert g/Kg into ratios.

In Oz the answer would be "suck it and see", which means you'll need to use the fertiliser yourself to find out how suitable it is for your application.

edit - the formula doesn't appear to have any calcium or magnesium which for cannabis growing are rather vital elements.
