When to flush & do I need to?

I have about three weeks to go before the chop. When do you usually flush and do i just use straight water? Or should i even bother ?
It's definitely a good idea to flush with hydro. You can start reducing the nutes in the last 2-3 weeks of flower and then straight water for the last week. Or, you can use a flushing agent like Clearex and go full strength on the nutes up until a couple days before harvest. :Namaste:

I personally don't flush, I run em up to harvest. Last few weeks they really pack it on so I keep em good and fed

Lots of sides to the flush or not battle....lol...I dont

Might just be the lighting, but they look like they could go a while longer to me. I sometimes have trouble with pictures, though. How many days have they been under a flowering light schedule? And were they mature when you switched to it?

Look like they've been getting too much nitrogen, too.

Get a ppm meter mate. It tells you how strong to make the feed. Number goes up add more water. Number goes down add more nutes. Number stays still or just drops a little bit then its sweet and youll get the best plant you can. From the nutrient side of things anyway :)

i just switched to straight water ,no nutes so a week or so will be 9-10 weeks flowering and some are cloudy now so i'll be hopefully around that amber area i hope. i have some sour jack seeds i am going to start next so this is just living and learning.. i'll let you know how the first bowl goes....

Personally i don't flush but there is a lot of debate on this subject... i think the cure is more important, nice grow though buddy :thumb:
are you running dwc jimbob ?
just curious. my personal belief is clearing plants is only relevant in hydro media.

edit: do agree the cure is the more important part.
