Multiple tops on bud

I have such a hard time trying to figure out deficiencies. Any suggestions on what this is lacking? Calcium, boron maybe?

Learning the difference between mobile and immobile nutes can help narrow down possible deficiencies. Mobile nute def will show in older leaves. Immobile nute def will show in new growth.

That's foxtailing, can be caused from heat or it could just be the genetics of the plant.

Looks a bit sativa anyways, Foxtailing is the norm for those guys lol

If you are in soil. DO NOT FLUSH. It only drowns the fuckin roots and wastes water lol.. just stop feeding 2 weeks before chop. If you're not in coco then there is no justification for pouring 10 gallons of water through dirt just to slow your plant down.

So let me riddle you this do your buds lose their green color or just your leaves? Chlorophyl is broken down when you dry and cure anyhow. Plus salts are built up in your soil not your plant and if your building up that much salt that you need to flush you may want to back off of the nutrients a bit. Plus I've done side by sides of several different strains both flushed and not and the guys and gals I had try couldn't tell the difference. The key is having someone that knows how to dry and cure properly that's the key. Plus like a lot of us have debated if flushing was really needed wouldn't you think they would?

Flushing must be a new thing, I can't imagine it was something that say Native Americans did. But then again bottled nutrients is also unnatural and new in the grand scheme of things.

Print this out and keep it close to your grow room

I look at that all the time, I still can't tell which it is lol can you tell what it is from the pics I posted?

Gotcha, started with the older leaves

Once something has made its way into your flowers it isn't going anywhere. Flushing does absolutely nothing to remove anything from the part of the plant you will be smoking. In fact, starving the plant during late flower just makes the plant go into emergency survival mode. At that point it will start to pull all available nutrients from your leaves to use as food. Anyone with an understanding of plant biology that didn't come from a stoner science blog post will confirm this. I've made this comparison before but I'll say it again. Expecting a 'flush' to do anything to your buds is like someone whose spent their life eating eating bacon cheeseburgers and chugging Mountain Dew expecting a weekend of a water only diet to make them healthy.

Flushing came about when people started to think they know more than Mother Nature. Like @KryptoBud bud said too once it's there no amount of water is going to flush anything and like I said if your feeding to the point where you need to flush you may want to cut back some.

Just to get a better understanding, not that I'm supporting either way... but these plants obviously get deficiencies from not having enough nutes. Won't they be using up those nutes and will no longer be present if not replaced? Or is it that they are just converting those nutrients into plant matter and therfore is no longer the same format as when applied?

Flushing is only good for one thing.

A big shit.

Nutrient deficiency can be caused by a couple things. The first and most obvious is that there is not enough of a particular nutrient available to the plant. The second is pH. Each element is only bioavailable in a certain pH range and if your medium falls out if that range the no matter how much you give it it will not uptake. The third is lockout caused by a imbalanced nutrient ratio. Excess of some nutrients tend to lock out other nutrients.

Right, but it's still lacking those nutrients. I'm just trying figure out why not to flush, or stop giving nutrients within the last couple of weeks, especially if someone is using synthetics. You mentioned that the nutrients would still be in the plant regardless of what you do, but is that really true if they can become deficient in specific nutrients? If it's taking the nutrients from a leaf, won't that leaf become completely void of that nutrient and die eventually?

You are correct in assuming that if the plant begins to feed off of the leaves for nutrients it will deplete the leaves and they will die off. But why would that be desirable? Also, I didn't say once they were in the plant they wouldn't go anywhere... I said once it's been used to produce flowers it's not going anywhere.

I'm just trying to sort it out. When you said flower I thought you meant the plant as a whole, my bad. Makes sense that you wouldn't want any part you smoke to be in bad shape, and that depriving the plant of nutrients won't alter what's in the buds. Also that depriving the plant of nutrients would only slow it's growth.

Thoughts on what my plant is deficient of based on the pics?

Going by just the pic you posted it looks as though it could be K and Mag...possibly P.

As for the flushing- I cant believe this debate is still going...especially with all the solid science and horticultural info available. Leeching the medium periodically throughout the grow, say in coco, can be beneficial when using salt based ferts. But that is only to prevent burns or lockouts.

In soil, or even peat based, you're drowning roots by cutting off o2 as well as causing pH dives from soggy soil. This invites all sorts of issues.

Seasoned growers understand the best cannabis is produced by keeping plants happy all the way through the grow. Plants use less nutes and feeds should be adjusted accordingly. Even a slight fade is fine but not to the point the plant needs to pull from itself.

Smooth smoke comes from a good cure. Period. Depriving the plant by "flushing" copious amounts of water the last 2 wks is foolhearted. The crackling black ash and harsh smoke is sugars that haven't broken down, again from poor curing/drying methods.
Nothing at all is "pulled" from buds.
