Thanks for the H202 tip!

Ive found that it's hard to over-do. Some people say that use during flower can give bad taste, but I haven't noticed this. I use about a large bottle of H2O2 (liter?) in my 120gal res every few weeks. That's about 45ml per 5 gal.

as long as you pay attention to the plant it can live in DWC indefinitely...

i just also saw that the TDS is a hanna primo pen...
if you can return i would. i had nothing but problems with that pen. very inaccurate. i could never get consistent readings. try calibrating the pen a few times and you'll see what i mean. hanna makes good products, but that is not one of them.

You got THAT right! Hanna Primo is a P.O.S.!!!!
It's better than nothing - but not too much!
