When to start flushing?

I have plants deep into the flowering stage, not sure what week as I’m new to growing. Hoping I can get some advice on how many more weeks to go until harvest and when to start flushing plants. Any help or pointers are much appreciated. Strain is Big Jack and I have them growing in 15 gallon fabric pots with soil.

Just keep doing what you are doing now for another 3 weeks or more.

Flushing is nonsense and not needed.

Would you starve your dog its last 2 weeks of life?
Feed till harvest just taper back on the amount of nutes used.

Sounds good. I’ll continue my nutrient schedule until the end. My other concern is the nighttime temperatures are going to get close to freezing in the next couple weeks. Will that cause any issues or will they have to be harvested early?

Shouldn't bother the plants unless it's a hard freeze (28 degrees or lower). The cold weather may get them purpling up a little. Agree with everyone else, flushing is for toliets!

I had 2 plants thats frosted over top to bottom last fall, they thawed out and finished fine. Just DONT TOUCH THEM if they frost over or youll bust off a lot of trichomes.

Ill see if i can dig up photos and add them in.
 
The day you think your plants are ready to chop, give them straight water for 3 extra days then harvest. That will satisfy your flushing urge and also not negatively impact your grow, since your letting it go an extra 3 days anyhow.
 
I flush my plants with plain water every 2 weeks during bloom to prevent lockouts or excess salts/fertilizer. Doing this, I noticed the overall uptake is unreal, I used to never flush or allow runoff, always had problems, flushing on the other hand, Never had a problem. I grow huge sticky buds that smoke white ashe. I do feed (not 10x the normal amount) plain water the last few days before harvest. Sue me.

If you over feed plants, they will be harsh even if you flush for 3 weeks, you can't take out of the plant what you already put in. Try feeding a nice balanced diet and cutting back on fertilizer near the end before harvest. Learn to feed by the plants appearance instead of the feed chart.

Watch out for mold (botrytis), check deep into buds for any weird grey shit or fuzz. That will be an indicator to chop immediately, that stuff spreads like wildfire once it starts and it's toxic to human health.

They still have weeks to go.

Flushing is a myth.

2 weeks before you think they will be ready, cut food by 25%. One week before harvest, cut it another 25%.

That’s what I call flushing lol. I’m 1000% convinced most of the flushing debate is based on miscommunication.
