this may be helpful/interesting. yes, ppms are affected. the nutrition facts on the back of food products are based on either a 2,000, or a 2,500 calorie diet.hi Hazy Lady, no haven't used that particular brand of coir
I haven't used molasses, was about to do a search after checking to see anything on coco forum and so here I am
I use canna coco coir, a+b, pk13/14, cannazyme, epsom salts, and rhizo. Unfortunately for me boost is out of reach, so I also will be watching but more importantly I will find some blackstrap in my country, and add to my feeds.
A question about ppms. I'll need to be taking the increase in ppms into consideration and scaling back something else? What did we say molasses is, a sugar? I am not up on NPK ratios and changing things like this might affect other levels and such......but like you, I'm thinking how to get a better yield for less cash out.
Also interested in adding more natural things, like making a worm farm and adding worm casting tea? Hmmm, wanna go organic but no time to learn new methods right now. so...
Does it affect ppms?
BTW, your mango haze, looks real nice. I smoked a haze a couple weekends ago at a friend's and the aftertaste was so fruity, so mango I loved it. until I saw the BBQ then I was off forgetting about those subtle flavors as the music gets my attention =)
so, for wholesome sweeteners molasses, @ 730 mg per tbspn (22 g), bottle states 20% of daily values (dv), or .2*3500 (daily recommendation for potassium intake)=700 mg.
have not found if this is listed as elemental potassium, or k20, which would have to be converted to elemental p, or .83*730=605.9 mg per tbspn. so, w/ pure math, would have 605-730 ppm per liter;
or 605/3.785=159.84 ppm k, or,
730/3.785=192.86 ppm k.
the formulas for converting mg/l to ppms should be on the linked thread. the nute calculator is good, too, though still not sure how it comes up w/ different #'s than the greenhouse math formulas. has to do w/ the weight/volume of the liquids; or the grams per ml.

calculating npk/nutrient profile (of molasses; still much work to be done...)
