I don't know either. A similar product from BioAg with humic and micros says the same thing about cal nit.
I'm going for fulvics and kelp instead.
Just an FYI for anybody else following along.
I knew all that going into it, but was convinced by many growers here and elsewhere claiming good results. The high ratio of nitrogen did cause me a bit of concern.
Too much NH4+ is what people generally associate with N toxicity. It's what causes that distinct dark glossy green color. Nitrate will cause a light mat green finish.
Yara calcium nitrate contains a 5:1 ratio of calcium nitrate to ammonium nitrate, which is "just enough" ammonium.
I disagree with using such low levels of nitrate in flowering. "why would you use such a high level of nitrates in flowering?". Easy... Faster growth, higher yields, and better overall health.
I agree that murate of potash (KCl) is something you don't need in your salt collection. You should have potassium nitrate instead.

always mix it ther same way/ratios, dilute to desired/target EC/PPM
for a higher EC/ppm add slightly less water
for a lower EC/ppm add/dilute slightly more water
take a minute and watch the yield numbers
notice the N for example in veg is higher and then drops for bloom and drops again in late bloom
meanwhile the P does the opposite as it increases while the N drops
these are good mix ratios youll be very happy with
And doesnt a nitrogen toxicity in veg delay flowering in flower
Wouldnt excess nitrogen in flower mess with my buds.
I learned to try to not use nitrogen in flower.
doesnt the plant accumulate all or most of the nitrogen it needs in veg.
Toxicity of anything will cause problems.
When did anyone say you should be using excess nitrogen? Such an annoying way to word your question...
This is misguided. Your plant needs nitrogen more than any other element.
NO! HELL NO!
in my opinion
theres never any reason to feed over EC1.5 regardless of medium or grow style ... provided your nutes are balanced
yes theres lots of guys who push the limits but your asking for trouble unless you've got a long history with a single strain and understand its max limits
most strains wont handle the high EC feeds as well but some will tolerate it
the numbers I gave you should set you around EC 1.5 +/-
maybe slightly lower
but you should be pretty close to spot on with the amounts I provided... what your using now is tooo much
