1841PPM

So I believe it's my battery, it was reading 1908ppm & 3617EC. Probably just get a new ppm & pH meter! Thanks for the help guys & I agree "FriedIsGood" way too early in Flowering or Flowering period, my ppm is almost always around 1100-1250ish

That's an EC of around 3.7.. phew that's a bit hot old boy...

that's pretty high. I would suggest you link your diary to the question, this way others will have the information needed to help answer. I'd try and cap that at 1200ppm MAX, so +641 over. Its also better to use EC as your measurement stranded. your pen should show both. EC is pretty universal where ppm can be on a few different scales. Hydro grows can take more depending on the size of the plants and what type of environment your working with. But even then, you will be pushing a lot more then ppm at that point, co2, PPFD, exct. Look out for lockout or burning on your plants, and if they are in hydro give them a little flush. If you growing autos they rarely go over 800ppm and that's only in the pinnacle of flowering. Some just won't get that high. Best Of Luck!

i think it to high for early flowering
