Do I need to keep feeding this plant for about another 2 weeks?

AlmightyJumpman · Jun 13, 2025

the reason this plant looks like this is because i have 2 of the same plant and im feeding them both the same thing not realizing they are maturing at different times. So while I flushed the other one, I was flushing this one as well thinking harvest was approaching but it looks like I still have time. The first picture was taken June 2nd, this how it looked before I even started flushing it which is why I thought it was on track with the other one. The leaves started to yellow on top and I thought it was senescence. That was the case with the other one, not this one. Do I jump back to nutrients after flushing for 2 weeks or let it do its thing with just water? The other pictures were taken yesterday. My medium is coco btw

Flushing is essentially starving the plant in hopes of a smoother end product. Personally I only flush if it’s for correcting an issue such as salt buildup. The last watering before harvest I usually just do plain phd water but I don’t “flush” them. I’m sure others will chime in with their opinions as well. I just don’t find it useful to essentially starve the plants. I’ve noticed no difference in buds from flushed vs non flushed plants. The real difference is in how you dry/cure them. Would you want to be starved on your death bed if you still had an appetite? That’s how I look at it haha

And just realized(stupid brain) you’re growing in coco so that’s a double hell no to no food. You should be decreasing ppm towards the end of flower but if growing in coco they have no reserves you need to be feeding them til the end.

Headed home now to feed them. Thank you

flushing have been proven unecessary.

in a blind taste test people prefered rather equally flushed and unflushed weed.

New Research Shows Flushing Plants Before Harvest May Be Unnecessary

In a blind taste test, researchers have found that many prefer cannabis that has not been flushed before harvest.

if plant are healthy and not fading too much near the end, flushing could eventually save a little on the nutrient bill

Or withhold both nutrients and water and aim for extra resin production from the drought stress.

If we want a slow dry after chop it makes little sense to deprive water before chop.

This must be the most contested piece of grow technique on earth.

48hrs dark?
48hrs drought?
FLush?

ON it goes. I like the "feed till end then a few plain waterings and chop" tech.

I soak my plants, then let them dry. So I feed every 3 days....let dry and feed agai 3 days later. If it drys out before 3 days I give it only ph balanced water. When its time or close to harvest....I just soak it with water a week to 2 weeks before. That's the only flushing that's needed....well in my world.

Someone said you was in coco. I’m in living soil, plant senescence on its own (it stops eating) but microbes still need to eat so I stop feeding and finish with horticulture coconut water

Some things to consider, science says plants make starches through the day that are used at night, if you iodine test leafs before the light goes out they turn black because iodine bonds with starch the same test done after a dark period stays white because the plants not had time to make starches, I should be clear idk if having a dark period would make a difference?

I don't know if it matters but it could?
The last of the nutrient going through the plants vascular system would be more concentrated.

funkdoctorspock said:

Water evaporates away but minerals don't so it seems logical that minerals taken up before chop are left behind in the vascular system after drying?

I don't subscribe to flushing but after I've decided they're ready I give them water for 3/4 days before harvest to empty the vascular system.

I don't flush I just stop feeding my regime and start using coconut for the finish while feeding the microbes. I guess watering with coconut would be considered flush...lol

I don't do any of those. I use soil with organic nutrients, though. Regardless, I can't see any reason to deprive the plants of what they need to live. So, I just try to keep them healthy all the way to the end.

I understand and don't, as for nutes.

My understanding is that at a point, the plants stop uptake thru the roots.
And take from the leaves ( hence the yellowing)
I can understand for those in pots feeding synthetic nutes/salt. But in ground....makes no sense to me.

Someone beat me straight, would ya.

No, a normal watering with water or coco water or whatever isn't a flush. A flush is when you send abnormal amounts of water through the media ... like 5 gallons of water in a 5 gallon fabric pot for example. The concept behind a flush is to have very significant run-off. This process has been proven useless.

Watering a normal amount of water or nutrients or microbe feed is considered normal plant care. I grow in soil so the last week to 10 days, my plants get water only but at their normal amount.

Do I need to keep feeding this plant for about another 2 weeks?
