Nerd Gone Vertical
I've been using dry nutrient salts for years, I'm happy to be of use.Absolutely. Let me know the exact spectrums your looking for.
@Lanestrainley and I have been talking recently about such things

Absolutely! Now when we're talking about soil, most of the processes that convert nutrients into water soluble forms are different. But the end goal is the same; water soluble nutrients, because plants can't absorb them any other way.And for organic growers worm castings are the bomb. The actual casing of each casting is a calcium based shell. So the elements you get from the castings are augmented by calcium in every little capsule.
No Sir! Epsom salt is great stuff because plants need the magnesium for metabolism and growth... and the sulphur? If you look at the chemical composition of most of your cannabinoids and terpenes, you'll find sulphur is an essential component!So epsom salt is useless?
Also with organics it's the long game. If my plants need calcium today adding castings isn't gonna do much. But the cover crops are also accumulators. Different plants accumulate different nutrients and if you are not harvesting the plant (chop-n-drop) it is returned to the soil and those nutrients are then available when the worms break them down.Absolutely!

Even the calcium sulfate (aka gypsum) that's useless in hydro is just fine in an organic soil environment because microbes will break that material up into calcium nitrate and either magnesium sulfate or mag nitrate, all of which the plants can use.
Hydroponics is just skipping the middleman and presenting nothing but water soluble nutes to the roots.
I wouldn't fight it that much. The main thing about organics is having stuff living and growing in your soil. I think in any hydro system having something growing in your water is usually a bad thing, right?Say ttystikk, I have been trying to puzzle out if there are any simple additives that you can add to your nutes in dwc to help with terp production which seems to be one of the only real knocks on hydro vs soil. Well, that and the fact that stop think and lift still needs to be very much a part of your lexicon. Have you ever went down that rabbit hole with any ingredients like sulfur or iron maybe?
Oh and I would love to know your mixing recipes!
For me I use beneficials/fungicide and make sure they are always growing and flourishing so there is no room for bad things to grow. A lot of people run sterile though and nuke anything that grows in their nutes.I wouldn't fight it that much. The main thing about organics is having stuff living and growing in your soil.

Yes there is; epsom salt. Seriously, it's that simple.Say ttystikk, I have been trying to puzzle out if there are any simple additives that you can add to your nutes in dwc to help with terp production which seems to be one of the only real knocks on hydro vs soil.

Sorta... The point of RDWC is to maintain oxygen saturation and proper temperature throughout the system. This tilts the playing field in favor of aerobic bacteria and microbes which are generally helpful and against anaerobic (without oxygen) microbes which are generally detrimental to plants.I wouldn't fight it that much.

You make a great point here about the influence of time. Hydro, especially RDWC, is RIGHT NOW, and if you guess wrong you can fuck your girls up in an hour. Guessing right means amazing growth rates.Also with organics it's the long game. If my plants need calcium today adding castings isn't gonna do much. But the cover crops are also accumulators.

Lots of fun science on both sides.
Thanks very much for sharing your mix/ratios and I am definitely going to give your Peak Bloom a shot here in a few weeks as I actually have a small bag of some MPK but didn't really now how much(or when) to use it.Yes there is; epsom salt. Seriously, it's that simple.
These are for the dry nutrient salts listed above. These are RATIOS, you dilute to your desired nutrient strength in the res and then pH balance at the very end;
VEG
4 parts of the 5-11-26 hydroponic mix
4 parts calcium nitrate (mix it into solution separately)
2 parts epsom salt
BLOOM
5 parts mix
4 parts calcium nitrate
2 parts epsom salt
PEAK BLOOM
2.5 parts mix
1.6 parts calcium nitrate
.75 parts epsom salt
.75 parts MKP
Use it for a few weeks starting around week 3 or 4 of bloom. If you use it at the end, you'll get more weight but you also get nasty, chemical tasting weed. That's where the bad reputation for hydro got started.Thanks very much for sharing your mix/ratios and I am definitely going to give your Peak Bloom a shot here in a few weeks as I actually have a small bag of some MPK but didn't really now how much(or when) to use it.
450nm and 390.Absolutely. Let me know the exact spectrums your looking for.
I believe you have Nitrate and Phosphate fertilizers. If I am remembering this correctly, you try not mix the two. You wanna match them up.PSA: Cal-mag IS MOSTLY NITROGEN.
Here's why; the only way to make calcium water soluble in a way that won't kill plants is as calcium NITRATE. Calcium also binds readily with sulphur so that's why you always mix calcium nitrate into solution separately from mag sulfate, aka epsom salt. When calcium and sulphur bind, they "flocculate" and become 98% water insoluble, fall to the bottom and remain unavailable to plants in your hydroponic system. That tan colored sandy shit at the bottom of your res is evidence you screwed up the mixing process.
So how do they get the mag in Cal-mag? Magnesium nitrate.
Soooooo... Calcium nitrate plus magnesium nitrate equals suddenly greener, healthier looking plants because of the nitrate.
Don't believe me? Look up nutrient deficiency pictures and see what calcium and magnesium deficiencies look like.
Thanks for coming to my Ty Talk!
I ordered some 365 and 485's. They should be getting here pretty soon.450nm and 390.
I'm leaning at the 450nm because that is the wavelength with my veg light. I have a ChilLed Mono Rail with veg board in it. They use their normal full spectrum but swap the deep reds for the blue. So id like to match that. (and ill admit I may be over thinking this). 365s, Thats almost to UVB isnt it?I ordered some 365 and 485's. They should be getting here pretty soon.
365 is still Uva , Uvb is around 310nm I think? Chilled make damn good lights.I'm leaning at the 450nm because that is the wavelength with my veg light.
