Hi SS,
Good to hear from you.
The water coming out of the main rez is 1150 ppm and PH is 6.4.
The water going into the Autopot rez is 950 ppm and PH is 6.4.
The water inside the Autopot Rez is 650 ppm and PH is 6.5.
It seems that as the water goes down the line, the ppm decreases and the PH stays much the same.
The water I put in the main rez is always about 5.9 PH. I did lighten up on the nutes a couple of days ago which may explain the decreasing ppm. Maybe that was the mistake. Still however, nothing seems to be way out of whack. BTW, RH stays around 40% in the day and 50%-60% at night. Temps are from 70 at night to around 80 in the daytime but occasionally reaches 82.
I suppose the next step should be to flush the container and check the runoff.
One fear that has entered my mind is the possibility of Tobacco Mosaic Virus. God!! I hope it's not that! I have researched the symptoms and TMV has many symptoms which my plant does not exhibit.....yet. According to what I have learned, a plant may not show all or even any of the most common signs.
Like my old countrified buddy used to say...." hard to say, not knowing as I do."
I will flush the container today and look for anything out of line. Hopefully it's just a Mn deficiency.
