S/H PHAL PH SPIKES

[rick84]

I am truly starting to think that it was improper circulation not allowing the plant to properly transpire. Just checked on her and improvements in leave stature remain consistent.

Erm, no, not exactly. You should probably read about osmosis. Osmosis - Wikipedia, the free encyclopedia
You can't "dehydrate a plant of nutrients". Dehydration refers to one thing - water.

AFAIK, once a plant has "grabbed" some nutrient, it's relatively hard to "suck it out" again - especially once it's taken up into an enzyme etc. Indeed, one could plausibly "suck the nutrients out" of a plant with pure water alone, if this were the case (see osmosis, once again). I suddenly feel sorry for all those rain-fed epiphytes. Oh wait, they're quite happy.

"over a 24 hour period" would suggest either you're logging EC continuously, or you measure every X hours where X is something like 1, 2 or 6 etc. and monitoring it for unusual fluctuations

Not trying to be pedantic, but when you're trying to use scientific terminology, it carries semantic meaning and you need to use it right, or people don't know what you're actually saying.

LOL- yeah they are

Im not understanding what you mean by units. like: 500ppm=1. ec or are you referring to my conversion factor setting used in calabrating nutrient meter?

My mistake, I did mean water. I use RO/DI water to flush out nutrient accumulations in my fruits and veggies I grow hydroponic.

Again I'm sorry for being unclear. The light come on at 5am. I take my reading at 6am. PPM<EC<PH, I log it. Then I will check again at 6 am the following morning. I am self employed so I'm at home a lot and I may check at noon and again an hour before light out. this is not a guarantee, but does happen frequently. a 24hr overall evaluation is a guarantee, and happens at 6am. I will go take a reading now and report soon.


LIGHT ON-5am
LIGHT OFF-9pm

PPM-210
PH- 5.73
EC- .381
Temp - 79 (root zone)
Temp - 82 (ambient)
Temp - 84 (plant canopy)
RH - 75%

these conditions seems to be favorable and optimal.
plant looks good

EC has units associated with it - like temperature can be 25 in Celcius or Farenheit (or Kelvin!); telling someone it's "40" outside without specifying units isn't exactly unambiguous.

There is not just one way of expressing EC - the most common measurement is microsiemens/cm (μS/cm) but there are others - they make a big difference (like the differences in magnitude between bit, byte, kilobyte megabyte, gigabyte and terabyte).
The manual that came with your probe should tell you what EC units it's actually using. The important parts to note are the magnitude of the Siemens (are they micro, milli or straight Siemens?) and the distance over which it is measured (typically centimetre or meter).

I thought I would put up a picture or two of the phal in question. Still seems to be doin good. More root growth and such a beautiful purple hue on lime green.

Looking good.
