Fatman,
I checked out your formula thread and noticed that the waste to drain Veg formula was missing. I scanned this thread and failed to locate it as well. Did I miss it? If so can you point me in the right direction or list it in your formula thread. Very much appreciated.

Fatman, thanks for the link, somehow I had managed to miss it. Using aero and DTW solves SO MANY problems, and not just with the nutrients! I guess it's my engineering background kicking in, but I really like the complete control you get with this setup - thanks for your input in the HP Aero Trees thread too.
Oh, a quick question: what ph are you assuming for the formulas posted in the other thread? Do I need to balance my water to a certain point first?

I assume that the assumption is that the formulas and the diluted mixes are made up with RO Water.

Based on what happened in his medium pressure drain to waste thread I dont think Fatman will be answering these questions... :[
\
True true.
I am thinking that fatman probably didn't intend to sound condensending, just a normal use of words in a acedemic world that isn't meant to be taken personally. But outside those acedemic walls what he says can come off as being insulting.
I would be quite happy for fatman to call me a child. Seeing as in the context of it all, I have very little experince in hydroponics so, I can be likein to a child that knows nothing.
Fatman,
I've tried to ask this questions many times and have never gotten an answer. I think I am probably not being clear...
I'f you have fert salts and the plants consumes them, are you left with some other salt that the plant wont use? I've heard the term 'spent salts'. I ask this because I only add water to my res and I ham seeing that the plants seem to lower the EC more than I thought. If I only add RO water back to get the EC to my target I eventually run out of nutes. I'm trying to say that I would have thought the EC would have remained a little higher and I would dump my periodically, but in reality I just add water and the EC drops. It is almost if I could just not have run off and use the nutes up (in a few days in my environment). I would have expected the runoff to be higher EC.
If my EC is at the target is there other stuff that doesn't effect EC that will be accumulating in my medium? Should I be leaching my soil with water periodically?

Hi there Fatman7574, firstly a word of appreciation for opening alot of eyes to the gross overpricing of commercial nutrients and preparations. It is a breath of air in an otherwise stifled room.
Have you given any thoughts to replicating House and Garden's, Aqua flakes? Alot of people seem to be gravitating to this bloom formula as it seems more ph stable than some others.
the specs are:
Part "A"
3.1-0-3.4
.3% ammoniacal Nitrogen
2.8% Nitrate Nitrogen
3.4% Soluble Potash
Derived from Calcium Nitrate, Ammonium Nitrate, Nitric Acid and Potassium Hydroxide
Part "B" is:
1.5-3.4-6.5
1.5% Nitrate Nitrogen
3.4% Available Phosphate
6.5% Soluble Potash
.8% Magnesium
Derived from Nitric Acid, Potassium Hydroxide, Phosphoric Acid, and Magnesium Sulphate
Thanks in advance and keep on formulating for us eager learners!

question for fatman, or anyone that can answer.
It appears that all of your nitrogen is derived from Calcium Nitrate, however, according to Wikipedia
http://en.wikipedia.org/wiki/Calcium_nitrate
so it appears that Calcium Nitrate has a high % of ammonium nitrate (NH4) as its nitrogen base, yet I have heard you only want to strive for a ratio of 1:9 nitrate vs ammonium. So, does only using calcium nitrate make your formula too heavy on ammonium nitrate??
I asked this exact question of Fatman and correct me if I'm wrong Fatman, the response was that the additional amount of ammonium nitrate was negligable compared to the overall concentration of the mixture. Basically, it contains 15.5% ammonium nitrate in the calcium concentrate. The small addition to the formula will not affect the overall recipe.

hmm, interesting, I hope this to be the case. I admittedly know very little about chemistry, but
5Ca(NO3)2.NH4NO3.10H2O,
it looks like there are
(NO3)2 + NO3 <- 3 nitrates
vs
NH4 <- 1 ammonium
so would that be 25% ammonium nearly double the recommended ratio?
EDIT: perhaps I am reading the coefficient wrong, but can anyone tell me about the 5 here
5Ca(NO3)2.NH4NO3.10H2O,
is that 5Ca or 5Ca(NO3)2? If it is the latter, then I think this does make sense, as we would have roughly 11 Nitrates to 1 Ammonium, so it would seem to fit the ~%9 profile

I think Fatman got banned. Too bad really, I learned more from him than the rest of the board combined. Probably banned under pressured from the Fertilizer companies because Fatman taught us how to make their formulas from scratch.

interesting, it was either pressure from fertilizer companies, or his somewhat "coarse" personality.
it seems like all the boards sponsors are seed companies, so I'm not sure if the fertilizer companies have an influence? oh well I am going to try to dig up some more info about that chemistry formula for Calcium Nitrate..

Its my understanding that the addition of the Potassium Nitrate KNO3 will knock that ammonium ratio down quit a bit too

For some reason there is a member who thinks I am responsible for fatman's banning. That couldn't be further from the truth. I have been involved in 3 seperate minor altercations with the fatman, this much is true. I also tried on at least 2 occasions to apologize to fatman for my role in these squabbles. He basically told me to get fucked. This last altercation which began in this thread; https://www.rollitup.org/hydroponics-aeroponics/334355-fatmans-medium-pressure-large-tube.html ............I asked him why he wouldn't post pics of his setup. He had said he was totally legal so I couldn't, and still can't, understand why he won't post pics of his setup without plants. We had a few words and it didn't seem like a big deal to me. Then he starts sending me threatening pm's. I ignored the first one and by the second one I responded telling him if he didn't like what I had to say to put me on ignore. He then forwards my pm to the mods and complains about me. This particular mod pm'd me letting me know what fatman had done and that I was in no trouble because there was nothing wrong with my pm and that I had broken no rules. I was also told by this particular mod that the fatman reported people on a daily basis and was basically all about starting trouble. I assured the mod that I would leave fatman alone. 2 days after I had posted in fatman's thread, another member started giving him a hard time. There was a minor altercation between the two of them, some posts got deleted by the mods, and fatman was banned. Now, we all know that fatman was anything but a nice guy but as much as I disagreed with his social charms I never wanted to see him get banned. I never reported him to the mods. He evidently was reporting anybody who ever disagreed with him though. The mods can't stand that shit. This is supposed to be an adult site and we should all be able to handle ourselves and treat others with respect. Anybody that is constantly running to the mods reporting people when they are as much at fault is probably not going to be too popular with the mods.
