when should i start flushing?

Hey.

When should i start flushing?

This is Northern Lights at 7 weeks.

Feeding with foxfarms,molasses and using 400w hps.

Topped it once.

Looks really sativa to me to be NL though.

Thnx!

You should flush a week before harvest.

Yeah...flush about 1 week before. It DOES look too sativa-ish to be NL. Most likely a cross.

i know i need to flush 1-2 weeks before harvest but when should i start the flush?

Anyone know?

Flush 2 weeks before harvest. Then do a flush 1 week before harvest... and finally one more about 3-4 hours prior to harvest. If you have some molasses, give them some in between flushes. If you can't give em molasses, give em some sugar water.

Molasses/sugar - 1 tbl spoon to a gallon of water

No nutrients

Flush with mollases till the end of flowering..a week before,stop all nutrients

Molasses make sure it's unsulphured. I use it with every watering...

Alright guys,lol.i think i may have worded my question wrong.

I am already using molasses.
I mean should i start flushing in a week?Should i already start flushing?
I dont know when i am harvesting.

Flushing at the end of a flowering cycle (just before harvest) is unnecessary and counterproductive.

How are we supposed to know when its time for you to harvest your plants? You're supposed to determine that yourself by using a microscope, a jeweler's loop or a magnifying glass and looking at the trichomes. If they are clear with a few amber colored trichs... and the pistils (hairs) are 80% brown. If you don't have any of those tools, you can just judge by the percentage of brown hairs. Post some pictures and we can help. If its sativa... you may have another 3 weeks.
