i havnt done any hydro or co2 for that matter, just a little studying, but 1500 is supposed to be the max, most benificial to your plants. it looks like your meter is just above 1000ppm. unless that is your nutrient meter. im sure you know this already though if you have a co2 system.

[oldsanclem]

normal background outside air ,with a good flow is about 300 ppm.
That is one way to check you meter out, do not do it inside as theres a build up of co2 from humans and other critters.

damn that looks purple

That meter that he has is a TDS meter not a CO2 meter. 1000PPM total dissolved solids it looks like.

Not 1000PPM CO2. He doesnt show how much CO2 is in the room.

Hey kiddo, let me help straighten out your many problems.
1 Walls- paint them flat white or cover with mylar.
2 Heat- I see signs of heat stress, helping #3 breed even faster, and you're gonna end up with herms in that stressful condition
3 MITES- look under those speckly leaves. I'll bet you find eggs and even webbing.
4 Root rot? Roots are too brown. There is something wrong there.

CO2 is USELESS when your other conditions suck. Don't even consider it until you have fixed the rest of your problems. Those tablets are a ripoff btw... when you are ready for CO2, it's worth doing properly.
