bobby: i don't believe in magic.
if they knew that their base nutes were calcium deficient in most cases, why didn't they add a few cents' worth of calcium nitrate, instead of packaging it separately and charging 1000x more? is there integrity in that? it may be a quality product, but there's very little value for your money. they're marketing products to cash croppers and med growers with a 400w light alike. http://scienceinhydroponics.com/2010/08/iron-sources-in-hydroponics-which-one-is-the-best.html
[allegedly] synthetic chelators aid heavy metal uptake (edta, dpta, eddha) while organic chelators do not (citric acid, glycine). organic ferts can have higher heavy metals, and synth nutes shouldn't be chelated.
Just to clarify that last post, I wasn't talking about getting base A and B formulations, but rather getting analysis on the Roots Excelurators and other products that are pretty impossible to reverse engineer without a lab test.
That sounds like mephatnuggz: fatman's bloom is 2.81-1-4.4. DM gold is 2-1-3, which has the same K/N ratio, and since P is relatively higher, K should be a little higher too. maybe 2-1-4? I must be missing something here, or you have a typo "and since P is relatively higher...". been there, done that. Also to clarify, I am using DM Gold A&B, not sure what that NPK works out to
jalisco kid's uses 2-2.3-5.3, which is very close to many nutes. I thought I saw him tagged with much lower NPK on this thread it seems that there is an ideal K/N ratio (around 3-4:1), however, P suppresses K, so the more P you have, the higher the K - and hence the K/N ratio goes UP with increasing P. you just have to use a fert and observe how your plants yield.
it just occurred to me that to dial a grow in, you have to turn the dial. True Dat, but only if you are growing the same strains over and over.
i've been hooked on 'house' lately (season 3 atm) and a negative result is still a result. if you can measure something, and change it with accuracy, you can influence the outcome. you also have to understand WHY it caused a change. i'm running experiments through other growers. selling ferts will allow me to compile a tonne of info. the guy that tries the most things and makes the most mistakes learns the most :)
General Hydro reversed Roots excel. There rep came into shop I am at and gave out samples. Its called rapid start. Not suprising was it has Alflafa extract for the triacontanol
Grow
Part A 3.5 -0.0- 1.5
Part B 0.5 -0.5- 2.5
Add.27 1.0 -1.0- 4
total 5.0-1.5-8.0 (K seems 700% hot )

stop it kuz, i'm blushing :)
phatnuggz: with any fertilizer, it was designed to work optimally at a certain ratio. get through one run and assess the results before you go tweaking the schedule. after you finish your bottles of dm gold, do you plan on mixing up your own with one of the recipes in this thread?
when asked about organic chelators i.e. aminos, citric acid, molasses, fulvic acid, et al., Daniel Fernandez had this to say:
"To the best of my knowledge there is no research which demonstrates any advantage to their use in hydroponic culture in general. They however do hinder the absorption of many micronutrients as they are very efficient chelators of certain metallic species. For example zinc gets very easily chelated by citrate ions so usually if you add a lot of citrate you’ll eventually get a zinc deficiency (this is what I have experienced on my experiments with this acid). An additional problem is that this chelating agents are “food” for microorganisms so they will increase the chances of outside microbe contaminations (including fungi and bacteria). Additionally plants do secrete oxalic, citric and similar acids through their roots so the little chelating benefit these substances could provide is probably already being “taken advantage off” within your plants micro-root environment. In the end I believe that most people use these things due to pure hype as experimental evidence up until now seems to suggest no significant difference from a nutrient availability point of view (at least in hydroponics). In the end a well-balance nutrient solution is all you need for very healthy plant growth."
so if you use aminos, you need beneficial bacteria to prevent brown sludge...or you can just omit both :P
I just read a paper on raising chickens and varying the micro nutrients in their feed. The alleged 'benefit' of using chelates is using less micros, and achieving higher uptakes. The paper concludes that aminos are NOT as important as optimal micro concentrations; and they don't double or triple bioavailability.
