@Capulator - I posted a couple of photos above.
Interesting that P is commonly and persistently present at 5 PPM, that's good info!
A lot of my research into hops points towards the following:
(Hops) Yearly application
75lbs(1st year) per acre Nitrogen(Nitrate)~ 37.5-75PPM
20-30 lbs per acre Phosphorous Pentoxide~ 13 PPM
80-150 lbs per acre Potassium Oxide~ 66.4 - 99 PPM
8.92-26.75 lbs per acre of Sulfate Quadoxide ~ 4.5-12.37 PPM
This suggests a respectable ratio (N-P-K) in the range of:
2.88 - 1 - 5
Up to:
5.75 - 1 - 7.5
Potentially:
2.88 - 1 - 7.5
5.75 - 1 - 5
My reading suggests that Calcium should be represented in relation to Phosphorous. I've even read that phosphorous can be peaked during different stages of life on different cultivars, as long as calcium is raised in relation. The ratio suggested in my research was. 1.5:1 Calcium : hosphorous. Another source also suggested that Potassium should be increased in correlation to Nitrogen at a 1:1 ratio, but potassium may exceed nitrogen without harm depending on cultivar. Another ratio I have noted is a 1:2 Phosphorous : Potassium (I'll have to dig through my sources but I believe that the emphasis is on controlling/regulating your maximum amount of P and not so much the K).
After a lot of reading and studying various articles, Im going to try the following PPM on my upcoming crop:
40 N - 20 P - 80 K - 30 Ca - 15 Mg - 12.5 S - 10 Sil
And
40 N - 20 P - 60 K - 30 Ca - 15 Mg - 12.5 S - 10 Sil
The cut of Cookies is up for debate. I've been told that it's a thin mint and ive also been told it's forum cut.
