Just curious if any growers have used this line of nutrients, mainly because Peters is unobtainable down under and it seems to be comparable.
I haven’t even seen these for sale in US, so not sure if anyone here will be able to help. I found AU site and it lists final npk ratio as 4.5-1-5.6. Npk ratio on jacks 321 recipe is about 3-1-4 if I recall.
So basically slightly lower in P, though otherwise seems to have everything?
Any opinions on the analysis?
Being technical, I would say more N and K and about the same amount of P. More calcium, less Sulphurl, and less magnesium as jacks using the 321 recipe.
I’m sure it would work, maybe require some tweaking here and there. Just like anything else out there, including jacks. There was not really anything special about the jacks 321 recipe other than cost. When it got popular and Peters started marketing to cannabis industry it became less affordable too.
Thanks for the chart, from what I see maybe low in magnesium and sulphur, though a little epsom would fix that if needed.
Exactly.
