I've had discussions with others who would debate that with you (the hydro bit, not the Ca/Mg bit). I just need to be certain that in this instance Crysmatic and I are on the same wavelength.yes coco is hydro, you need to add a bit more cal+mag i think though
Aha! A way to make the distinction, thank you!jk posted a link in his nute thread: http://www.usu.edu/cpl/research_hydroponics3.htm "Plants have evolved to tolerate large nutrient imbalances in the root-zone." could it mean that anything from fatman's 2.8-1-4.4 to maplereef's 1.7-10-5.1, and anything in between work? if you change the res weekly, or run dtw, then you provide enough elements to prevent deficiency, and not allow elements to build up and cause toxicity.
Hydroponics (From the Greek words hydro, water and ponos, labor) is a method of growing plants using mineral nutrient solutions, in water, without soil - wiki. the key word is 'mineral' - medium isn't relevant. any time you rely on microbes breaking elements down to make them available to the plant, you're drifting into geoponics - geo = soil.
I am nowhere near your or budboy's or JK's level of expertise with playing around with nutrients. What I can say is this--I've used P/K boosters, such as Liquid Koolbloom, and the results were nothing like what I see with this.seamaiden. i 100% agree that plants make aminos. my argument is that they manufacture them, not consume them. any benefit seems to result from soil health and their chelation factor in geoponics. running pk and aminos simultaneously won't tell you which component is responsible for the growth. run your own test. make your own 0-1-3 without aminos, and use aminos without the pk, and see which gives better results. you may find that aminos potentiate the pk (work better together than each running alone).
IF aminos potentiate, as you suggest may be a possibility, then that's something worth some consideration. Now that I've gotten another harvest under my belt (chopped all my Kush and White girls two days ago) and I have some Big Up with which to experiment, as well as some MAP & MKP, next run (I'm thinking Blockhead) I shall divide up the tables and give this a go again--will the Big Bud's aminos be the difference, or something else? Curiosity makes life interesting.

I'll agree with that, definitely true with coco if not, so far as I'm finding, not true with a medium such as perlite.having a reactive medium means you have less control of which nutrients are available to the plant. it seems soil and soilless media can't tolerate as high P as pure hydro. then again, it might just be that the range is so large, that nute companies arbitrarily change up the ratios (while staying within the range) to convince you to buy more product. it seems fairly lucrative to have a hydro formula, coco formula, and soilless formula; plus three kinds of bene's, four kinds of bloom boosters, rooter, enzymes, cleaner, extra micros/kelp.
Something more to read that helps explain what's up with coco, and a whole lot more, perhaps may round out or simplify what's held within that excellent site JK linked to elsewhere and you've re-posted:
That's the liquid, I don't use the liquid, I use the powdered. Powdered is something like 0-15-40 + a huge list of those aminos we've been batting back and forth. ;)fyi, big bud 0-1-3 is:
4.4g potassium phosphate
9.5g potassium sulphate
per L of solution. this is less than $0.20 worth of salts! one $6 500g tub of potassium sulphate will make 52L of big bud...over $2,000 retail. AN brags about ROI with their products. lmfao
generic 0-2-4 (0-9-18 uses 4.5x the quantity)
8.3g potassium phosphate
11g potassium sulphate
