constant cal same % as n good.

it is primarily immobile, but can be translocated, as long as transpiration occurs @ fast rate.
Anyone want to take a stab at why manufactures add epsom salt to Carb products?
FWIW, the CeS carb product is Uncle John's Blend, not Mag Amped.
I.E. If the humidity is too high, the plant cant transpire, they can't move/use Ca.
only imaginary tomatoes... never read their techs. no nute is specific. ea cultivar has its own profile.That is all important information, but i still wonder what these (alleged) canna specific nute lines use as their ratio vs general hydroponics 1:1. (for instance i think ive seen AN literature, or a Big Mike video, recommending a 1:0.8 N:Ca)
most water is not additional calcium... the calcium has to be in soluble form to be assimilated by the pl@nt. the calcium in tap may/may not be available. there may also be copper, lead, nitrates, etc that alter final profile.Given the fact that most water is an additional source of Ca, it would seem that a nutrient line with a 1:1 N:Ca, may be anticipating a higher Ca than N. IDK.
slurryWhat type of process is used by FloraNova
small amountsCNS17, ect, to bottle the Ca with the P and S?
if the 1 part shaken well (fnb) warm water and agitating to dissolve may help. most have low cal content. fnb have higher cal & work well for 1-part @ 1-3 tsp gal.Conventional wisdom says they are better packaged separately, what are the effects/consequence/etc, of using a '1 part' (other than lack of flexibility)?
I am far from an expert in water quality/analysis. However, to say that tap water is not a source of Calcium seems incorrect. What % of Ca, in tap water, do you think will not be usable to the plant?most water is not additional calcium... the calcium has to be in soluble form to be assimilated by the pl@nt. the calcium in tap may/may not be available. there may also be copper, lead, nitrates, etc that alter final profile.

Calcium usually enters the water as either calcium carbonate (CaCO3), in the form of limestone and chalk, or calcium sulfate (CaSO4), in the form of other mineral deposits. The predominant source of magnesium is dolomite (CaMg(CO3)2).
Example 1 - when calcium carbonate, in the form of lime, is added to an acidic waterbody:
-the lime will cause the water to become less acidic (the pH will become higher);
-as the water becomes less acidic, phosphorus, a necessary nutrient, will be converted to forms that then can be used by plants, potentially stimulating their growth.
Example 2 - when a waterbody is not acidic (with a pH above 8.2) and contains an abundance of calcium carbonate:
-calcium carbonate will combine with the phosphorus in the water to form a solid called a "precipitate", that can sink to the bottom or be attached to aquatic plants;
-plants and algae will be deprived of phosphorus and their growth can be slowed.
can03-, or cacl far more effective for application as water soluble fert. maybe...Calcium carbonate is poorly soluble in pure water...Two hydrated phases of calcium carbonate, monohydrocalcite, CaCO3·H2O and ikaite, CaCO3·6H2O, may precipitate from water at ambient conditions and persist as metastable phases.
gma?ShroomDr said:(I have not looked hard, but i have never seen a 'hose-attachment-having garden fertilizer' that lists Ca anywhere near the N levels in the GMA).
gma?
GMA = Guaranteed Minimum Analysis
what is 'hose-attachment-having (garden fertilizer)'?
it can be explained by fact that most dry type ferts dont contain any cal - it is generallyt always fed separately to make sure it get thru w/out antagonisms or precipitation or reactions w/ other chems...All Ca in tap water, may not be available to the plant, but the fact that GH makes a Flora Micro HardWater, with 1/5 the Ca of Flora Micro, has to mean they are considering the tap water as a major source of Ca.
How else could someone explain the 80% drop in Ca, the plants must be getting it from somewhere...

I agree with all of this, its not in contention, however i feel you may be OVERSELLING the 'may alter cal availability'.limestone & gypsum are not immediately available...
often, other chemicals are also placed into muni tap, which may alter cal availability.
Huh? You lost me here and the ellipsis are yours. It seems like you are saying there is no calcium in the formula CaNO3?most dry fert dont contain any cal... but not due to tap having some, but because tomato, basil, pepper etc greenhouse gardeners just ca-n03-....
Is Maxibloom 1:1 N:Ca too? FNB is made by General Hydroponics, so they stay with the general ratio of 1:1. That doesn't surprise me, in fact if they used a different ratio, i would say that would be noteworthy.see maxi-b & fnb. they both have same % of n:ca, although even those may precipitate if not shaken/mixed very well...
liquid ferts were once dry ferts. the precipitation can still occur, even if the elements/compounds are dissolved. it is the mixing of certain chems in high concentrations that causes new compounds to form, which may.may not be available to pl@nt.The GH Flora Series is liquid, i dont see why your 'dry type ferts' explanation would even be relevant (The very reason they these liquids are separated into 'two parts' is specifically because of your explanation [antagonisms, precipitation, reactions between molecules]).
the point is to have a separate source of calcium, ideally held in its own tank. if ShroomDr permits tap water to e the source of cal - go ahead.Flora Micro is the only bottle that has Ca. There is none in Flora Grow or Flora Bloom, so there is no other source of Ca in the General Hydroponics Flora Series.
1.) The Flora Series has two versions of Micro, everything is identical except one has 80% less calcium.
2.) This version with the lower Ca is labeled the HardWater formula.
3.) Hard water insinuates Ca in the water (among other things).
not selling anything. if tap-cal works for gardeners, use it. only found that separately feeding cal work well...I agree with all of this, its not in contention, however i feel you may be OVERSELLING the 'may alter cal availability'.
cal is not the pnly element in tap. there can be lead, copper, nitrates, uranium, etc, etc... depending on what is used to raise ph over 7.0 for human use, can affect final cal availability. the cal in tap is not added by muni's it is variable.Again, I dont know much about water analysis, but if hard water is an excess of Ca...
And the formula suggested for hard water has 80% less Ca than the regular formula....
It seems pretty easy to me; 2 and 2 is generally 4.
can03- is calcium nitrate. check 'derived from' on most any fert bottle... what is commonly used for cal & nitrogen in h!dr0 type ferts.Huh? You lost me here and the ellipsis are yours. It seems like you are saying there is no calcium in the formula CaNO3?
Or was it, as it reads 'ca-n zero three-'?
If so, I dont know what "greenhouse gardeners just ca-n03-" is suppose to mean.
cal required by plant may be +/- of n%, but it works better. whatever makes your plants happy.Perhaps you mean greenhouse gardeners foliar feed with calcium nitrate (preventing Blossom End Rot), but i am making inferences based on my own knowledge of calnitrate and BER; the blurb posted wasn't too clear (and greenhouse [high] humidity conditions cause Ca issues [necessitating a fix]).
yes, mabi-b is 5%n, 5%ca...Is Maxibloom 1:1 N:Ca too? FNB is made by General Hydroponics, so they stay with the general ratio of 1:1. That doesn't surprise me, in fact if they used a different ratio, i would say that would be noteworthy.
because most greenhouse gardeners supply cal separately...
Again not trying to argue, just asking for clarity, I dont disagree with the principles you have laid out, just possibly/probability of their application, and I will happily say i am incorrect if there is another reason for an 80% drop in Ca with a formula for hard water (other than the excess Ca in hard water).
This is a great thread!
Shroom, Mistress...keep going plz.
MY HYPOTHESIS FOR THE THIRD TIME
the fact that GH makes a Flora Micro HardWater, with 1/5 the Ca of Flora Micro, has to mean they are considering the tap water as a major source of Ca.
How else could someone explain the 80% drop in Ca, the plants must be getting it from somewhere...
ShroomDr is not 'permitting anything' GH is contouring the lineup to accommodate for the Ca in a 'hard water' supply. GH Flora Mirco Hardwater lists the EXACT same Guaranteed Minimum Analysis as GH Flora Micro except an 80% drop in listed Ca.if ShroomDr permits tap water to e the source of cal - go ahead.
IF this applied to the point being made, it would insinuate that most greenhouse gardeners are using RO water. I do not believe this to be the case. Not any greenhouse around here.because most greenhouse gardeners supply cal separately...
No its not. can 03- is nothing (i am aware of). A Zero instead of a O is a major error, one you continue to make.can03- is calcium nitrate
He doesnt seem too concerned about unusable Ca or other compounds; perhaps thats a better place to discuss what 'ShroomDr permits tap water to (do).'BigToke said:
BigTokes ~ Basic Water Chemistry!!
Did you know ~ that instead of buying an expensive R/O filtration systems that you could have simply bought nutrients that was formulated to meet you hard water needs? Expensive filtration system are made for people how are drinking there water, not growing in it (in most cases)!! With the exceptions of very polluted water conditions...
...The water that I recommend to use the most in the Bio-Bucket System is simply tap-water, most tap-water has a buffering capacity that is due to carbonates and bicarbonates.
...this is just another reason that I recommend tap-water if possible.
