And none of you know how much calcium is in the cns17?. It has equal parts cal and nitrogen. I use amino products i listed them. All i wanted to know is what deficiency that appeared to be. I think its calcium toxicity mixed with nitrogen toxicity.
I don't know what one to answer first....You want this, you want that, but you want it your way...And my bioag buffers my ph. No matter what it will go back to 6.1 and they been doin so for the 4 months of veg they are in. I know what ro water is.
Lets start with this!
Your bioag FulHumix does not "buffer" your RO! That is Fulvic and Humic acids. Those do not "buffer" anything..
Did you bother to read that your pH should be rising naturally? You don't want it to "sit in one spot"! Do you know that Ca is better uptaken over a pH of 6.0 ?
You give us pics of a cpl of mealy leaves. How about a pic of the whole plant? That way we can see just how it looks and what it tells us! There is SO MUCH information missing in just a cpl of leaf pics!
Now then, as for your Ca and N being the same amount.....N = 3% by .14 being an Ammonia Nitrate and 2.85% being Nitrate based Nitrogen.
Ca is 3.6% and is made up of Calcium nitrate. The source of the N. nitrate is mostly the calcium nitrate! That is a short cut way to save money in making a nutrient (They are counting the Nitrate in the Ca. as part of the "nitrate of Nitrogen") .... The problem is that Ca Nitrate is not as good a buffer as Ca CARBONATE!.
Secondly, there is not enough Ca in 3.6% to buffer the RO and feed the plant!
Back to the pics.....You surmise a Ca tox when there is not enough Ca present to even buffer the water properly.
You surmise an N tox, because your adding the N value to the nitrate in the Ca aren't you?
While your pics suggest there could be a slight elevated N. With out whole plant pics.....NO ONE can tell with ANY certainty!
This is what I see - PERIOD. You don't have enough Ca and the plant has a Ca def. The pH rising from how ever low you set it (you don't say) appears to be fine as we don't have enough visual information to confirm this.
The N appears to be acceptable in the expression limited leaf pics given......The lower pH could be the affect of that higher N look as lower pH favors N up take over Ca, P and Mn...
"I" would like to see more Mg available also.
So then...You are mistaken..
Ca tox? NO!
N tox..Most likely not but, not enough visual information available..If there is, it appears to be at an acceptable level - almost wanted level at this point.....3-1-2 ratio's look that way when properly applied!
Simple solution - Add at least 3ml of Calcium carbonate based Ca/Mg per gallon of feed in the res. You could even run 5ml and NOT have a Ca "tox" problem......May I suggest CAli MAGic from GH as it has the lowest available "N" value on the market
Does the plant have deeply (not just the ends) down turned clawing and shiny, very dark green leaves? THAT would be N tox to some level (higher)...If not, simply keep going!
Lastly...
It helps a shit ton, if you list everything you mix in and how much.....Not to mention pics of the effected area/leaves but the whole plant also....
If someone comes in and is being nice by giving you info that they feel you might need a brush-up on, due to your message and to other answers.....Be patient with them.....they're trying to help.
BTW, and with all due respect. Believing that FUL HUMIX will act as a "buffer"....Tells me you know less about RO then you think.
I attempted to answer your questions with respect and yet fully answer them. Be patient!
