this is my first time running this regimen...so i have no basis for comparison. this is also my first time mixing my own nutes, and first time running soiless outside. my colas are filling in now...i'll let you know how dense they are when they're done.
what is it about KNO3 that makes buds loose? do you use ammonium earlier in flower?
i just ran ripe in hydro buddy with potassium sulphate, and no potassium nitrate. i get 69-151-229-85-35. the only difference is calcium goes up about 13 ppm. there's the same ppm of nitrates...so what's going on here that makes harder buds?
mejuana: purity has to do with whether or not a salt is cut with an adulterant. Pure MKP is 0-52-34. 100g of pure MKP contains 52g P (really P2O5). shooting powder is 0-39-25. 100g of shooting powder has 39g P. 39/52 = 75% pure. does that make sense?
edit: epsom salts is magnesium sulphate heptahydrate. it is 9.86% magnesium. wiki is handy for molar masses.
Don't know if you've already tried these guys but they have quite alot of products.
These guys are in socal as well...

Doing exactly the opposite would be fantastic for coco growers. Coco coir is already high in K and sucks up Ca and Mg like a McFatty suckin' on a McShakey-shake.Re: Why use Potassium Nitrate and Calcium Nitrate
I thought it was just the ratios you were trying to achieve... Calcium Nitrate is 19% Ca and 15.5% N right? Say I want a different ratio of Nitrogen in comparison to Calcium, now you need another source of Nitrogen so I choose Potassium Nitrate
Green Leaf Aquariums
Potassium Nitrate (KNO3)
13.7-0-46
So now I am untied from Caclium I can boost N and K at these percentages, if I run out of room on K and I need more Nitrogen, shit now I gotta find another one.. Or rework my chems from the start.
I use DAP 3 times as a floral spray for flavor changes after reading some Indian studies using it. They seem to be pushing the envelope more then other countries. JK
It was something I noticed when I had to change up a formula due to lack of salts. I then had a patient run overdrive instead of big bud from week 2 on. He ended up with less heady trics. I usually add K nitrate 2 weeks before flush to pump them up,that and K phosphate. I use DAP 3 times as a floral spray for flavor changes after reading some Indian studies using it.

very interesting JK! like you've said before, the K is what really pumps up the buds. what was your patient using as base nutes? can you give me an idea of NPK he was running?
i've made (and am using) 4 formulas:
veg/early bloom: 3-1-4
middle bloom: 5-4-10 (connie) and 5.5-6.5-12 (connie + OD)
late bloom: 1-5-4
from your observation, i should drop OD. i wonder whether in late bloom i should continue with 5-4-10, 1-5-4 or maybe 2-4-10? (hammerhead)
when and how much DAP do you spray on your plants? how does DAP affect flavour?
I just found this comparison of DAP and MAP, thought some who are playing around with this might find it interesting, useful.
Some might find this useful as well (apologies if it's been posted):

Is this still true that you find differences by hand calculations with Hydrobuddy? How did you learn how to calculate it all out using molar masses and etc. That is so damn confusing.
Edit: squarepusher do a search for a program called Chembuddy, it has all the molar masses and some technical info with a 30 day free trial, fun to play with.
I'd say his calculator is good
