Flushing ppm

Manijuanastarted grow question 3 years ago

I'm starting to flush my girls now! What is an acceptable range for my ppm in runoff water when flushing for harvest? I'm down to about 700 ppm now but could take it lower.

Way too high. Target is 200 even with RO water, I know people are struggling to drop below 400 without drawning or bringing mold to plants. Good page for you : https://www.cocoforcannabis.com/when-and-how-to-flush/ Good luck !

Transplant shock Soil was too compact. Lower leaves yellowed then died. Transplanted at day 11 flower in light soil and watered with nutes (humic acid, silica and NPK in flower schedule). Top of main stalk drooped but side branches seem fine. Lost some roots during transplant. What should I do?

GD web site issues ...Has anyone thought of taking a month off so that GD could fix the problems? We should just take July off so they have room to work. Then, if we can't send a simple image url to a friend without a 7h ban after that time, we can take august off too. Rinse and repeat
