PPM Question during Pre Harvest

[weediologist]

Okey i flush my plants and they are only getting water for 2 weeks. i growing hydro. now i stated on Jan 12 2007 with a PPM of 205 and pH 6.1 and today Jan 17 2007 its PPM is 450 and pH 5.9. so my question is, does PPM suppose to raise like this, should i topp the plants with more water to low PPM? or wat do i do?

If you haven't done anything to your res since 1-12-07 I'd suspect there's less water in there due to plant usage and evaporation so the concentration levels are coming up. Adding water to lower the PPM is logical.

Racefan...your thoughts?

DnB - you mean only flush for 2 days? Seems quite short.

Flora Kleen is a flushing agent that is suppose to rid the soils and plant of excess nutrients huh? I wonder what residue if any they leave behind? And if any, is it organic? I myself have never ever tried a flushing agent before so I can't really talk about how well they work. 2 days does seem like a extremely short period to rid the plants and soil of nutes. How well does this stuff work when used for 2 days DnB? I don't mean to knit pick but the directions in the "Linky" you posted says to use a "few" days.
