For some reason it seems that the PPM of my nutrient solution is being affected dramatically by the light. Is this normal, or possible?

Just got the meter today and calibrated it.

With the light moved off the plant

With the light directy on the plant (about 6 inches)

Well, light doesn't create particles (ppm) and I don't see how it alters conductivity (EC). So I vote for gremlins as the cause

I dont' think it's the light itself. might be the fixture?

When I just touch the bucket with my hand, the PPM decreases by 200. Is there something wrong with the meter or something.

I have them Hana Combo (http://www.4hydroponics.com/grow_room/grochek.asp), mine changes PH, and Temp when the lights come on. Still don't know what causes it yet. I have not tried to recalibrate yet either.

My Ph seems to raise like .1 pH every 10 minutes, but is anyone else having these problems with a Tri-Meter.

The meter better not be funky it's a brand new Nutradip. i'll be po'd

This sucks man I have to go put 1 gram of pH down in the bucket once every 60 mins. What the heck is going on?

I dont' know if it's the light, the bucket, the bubbles, or what
