Yes, also Cal Mag is a known coco def too... so I could be victim of double "under-flipping".
With DWC though, its a different story. If the rez has a competent bubbler going, and ambient temps are ok, then everything should be ok. The better light
spectrum (PAR, photosynthetic active radiance - radiance that the plant actually uses, and Photosynthetic Photon Flux Density (PPFD) - the unit that measure the quantum), the more nute demand from the plant, hence the deficiency, but also better the final result.
Now this is just my theory so far... If the plant is stressed and it stunts, then the only way to fix the problem is with high radiant energy, a.k.a - HID.
because it really make the plant transpire. One thing is the plant being healthy and naturally hungry at, say 21ºC... another is to have 30ºC and force
the plant to consume water (and so, nute) in order to keep alive.
The plant doesnt have a central nervous system like we do, when we starve we go into "zombie" mode until food is in us, whatever it takes. A plant works with
osmotic facilitated pressure, so water vs salt concentration is what commands the intake. Force it to "sweat" out water, and the roots will suck up whatever it can find. So nutes also go in, and the plant get better.
So in that regards, LED is not the best thing around.
But... if the whole plant biology is working, and the plant consuming the nutrients to photosynthesize properly... hence altering salt
concentration, then it does take in food for food's sake, not for the waters sake, so it consumes LESS water but eats up all the nutes. So at 21ºC, it has the maximum growth potential.
Actually, thinking about it, this maybe exactly why DWC and LED and autos seem to work so nice together.
Dunno, its a theory, anyone care to chime in?
