when to harvest

yeah, im guna give it another 5 days then might flush, or grow for another 5 days, and see how it goes

Well I waited to long to flush. Need to harvest right away
i have given them gallons of straight water for 2 days
how low does the ppm reading have to be to be safe to harvest
I am using cuting edge in perfect pots and have put 3 gallons of fresh
water on each plant till it runs off

There are some drinking glasses that with a little water you can get about 10x magnifying glass either from looking down into the glass or across the glass.

Not the best but better then nothing.
