Day 91 when to flush coco

[Nacho34]

So day 91, maybe 2-3 white pistils on each bud. Not sure if thats just new pistil growth. Some sugar leaves have amber trichs. Still clear trichs on the buds themselves. Question...when should i start the flush being its coco/perlite. Being my first grow i dont want it being too late. -- sensi seed white haze/ Anyone have a ballpark est. On the yield later on, i know its hard to tell with the pic. In a 3x3

No expert here,just read a lot...
If you choose to flush usually 6-8 days before chop but you'll get all sort of answers from 2 days to don't flush it's a waste of time.You'll have to do like me and experiment to make you own idea.
2 first plants i flushed for 7 days and the third one had no flush.I was carefull with drying and curing and all 3 taste really good and can't see a difference yet 2 months after.
Don't think i'm gonna flush the second grow...
Plants look good and i will guesstimate about 120 gr.
Good luck!

Flushing is optional.. If you choose to "flush" you will need to decide what you consider "flushing" to be. Some consider it running a large amount of water into the pot at one time, until the ppms are as close to zero as possible. Usually 5x the pot volume. So a 3 gallon pot would be "flushed" with 15 gals of water. Others consider flushing to be reducing the nutrients to around 1/4th strength for the last 1-2 weeks. Others say it's using straight water for the last week or so. It all depends on how heavy you've been feeding and whether or not you use salt based nutrients. The heavier the feeds/salt build up, the longer the "flush". In coco the norm is 5-7 days before harvest. When you harvest is total personal preference. Depends on how you prefers the effect of the buds. Clear is more psycho active.. Amber, more couch lock.. Milky, is a mix of the two. Unfortunately there isn't a way to guess yield by pictures. The flowers could be dense.. Could be loose ect. Looks like it will be a decent amount though!

When I would do coco, I would push the feed Strength mid bloom then by late bloom be back down to around 1.0 EC. Then a few days before harvest I stop watering and let them die.

Can't tell you yield. The way you dry and cure it will be there only way and, I believe, you lose upwards of 75-80% in water weight.

Is there a reason you want to flush and not just feed regularly until harvest?
