Sick seedlings.

Pretty much anything that comes through that can be calibrated, I do. Leaving less to chance is a good thing.

Yeah I upgraded to a blue lab truncheon thinking it was a must for all hydro growers.

I prefer to use my $7 shitheap meter because it displays exact figures not .2EC intervals like the truncheon. Good to have a couple of options to compare against.

The Bluelab truncheon measures .1 ec intervals.

From the Bluelab website:
"If the flashing lights are alternating between two numbers, the measurement is the value between those two numbers. For example, if the lights are alternating from 0.8EC and 1.0EC, the reading is 0.9EC."

Yes I know I have one.

The point was my cheap ec meter is accurate enough when compared to the truncheon that only gives a range anyway.

I think it was a light issue. Since i have cut the light back from 75% to 40% the leafs have perked up a bunch. Thanks all.

Its a blue lab ppm meter. They come calibrated righ, also use my vivosun ppm meter to compare. The vivosun reads 10 pom higher than the bluelab.

Blue lab pens will have a tick in the bottom corner if its been calibrated.
