Ok so I have a question can anybody tell me why with me being so late into flowering (wk6) that my girl is now starting to show new white pistils?? I’ve got about 70% of it already covered in amber colored pistils and all of a sudden yesterday I noticed new white pistils…am I doing something wrong??
sounds normal a last ditch attemp to pollenate
Can you post a picture of your plant
What are your temperatures ? Sometime excessive heat will stress a plant to do that and possibly cause it to foxtail in some cases . Just a thought !
@Countryboyjvd1971 is right in my opinion. When she’s commING to the end of her lifw cycle she will throw out new pistols as a last ditch effort to get pollinated.
@Countryboyjvd1971 @Seeddog @Sirsmokes thanks for the info…I did read that somewhere about the last ditch effort towards the end…here’s a pic I took a few days ago, there’s 2 buds below this one where I noticed the new pistils lastnight
Temps are 45-50 humidity and 75 temp
No heat stress at 75* . CB and SS have you covered on this one . Humidity during the flowering stage would be ideal at 40 % . That bud looks great .
Nothing to be concerned about… she just dun want to die a virgin.
@tanlover442 good one
@Boogie021 - Sorry to jump in your thread but I have a question for @Seeddog , while reading the thread I saw that you mentioned “foxtail” , can you please tell what that is , I never heard that before. This is only my second grow but I read a lot , journal after journal , I learn more from others journals than I do “The Bible” , LOL!!!
Thank you so much and I’m so sorry again Boogie
Thats how I knew about Foxtail , by reading about it here . lol . Basically it is caused by some sort of stress on the plant . Heat , cold , lights ,nutrients . Here’s what I found …What to Do About Marijuana Foxtailing
Picture some dried and cured, ready-to-smoke bud in your mind. Maybe it’s some you’ve harvested yourself, maybe it’s some exotic-looking unique strain, or maybe it’s just a generic picture your mind pulls up when you think ‘weed’.
I’m sure there are a few exceptions, but I’m betting most of you didn’t automatically picture this:
Picture of a cannabis bud with a major “foxtail” coming out the top. In this case, the foxtailing was caused by too much heat, though some types of foxtails are caused by genetics.
See examples of “good” vs “bad” marijuana foxtailing below!
This picture is the definition of (one type) of foxtailing!
We tend to think of buds having a round, oblong shape with a pretty much even surface like this:
A marijuana cola with a typical shape.
The classic conical bud shape!
Many auto-trimming machines cut off foxtails, so if you used to purchase cannabis regularly you may have bought buds with foxtails without knowing. That’s not necessarily a bad thing, though!
So, What Exactly Are Foxtails?
The bud we know and love is made up of a bunch of calyces (that’s the plural for “calyx”) and each calyx is a potential home for a seed. However, those seeds will only develop in cases where pollination or hermaphroditism (developing both male and female sex organs) occurs.
Buds are made up of many calyxes stacked on top of each other, but generally, buds grow evenly and stick together in bunches.
Why, aren’t you exotic looking?
As female cannabis plants mature and soak up light, they grow calyces in groups which pile up on each other until they end up looking something like the plant above. Even the more exotic looking strains tend to form buds with a somewhat even-ish surface:
“Foxtails” are made of several calyxes stacked on top of each other in a relatively long structure.
Even when you can very clearly see each individual calyx (which is natural for some strains), they tend to be relatively symmetric, with a similar amount of “foxtailing” on all sides. (Why are these buds pink and purple?)
Example of an exotic purple cannabis bud with natural foxtails
Foxtailing buds look a bit different from traditional buds because the calyces grow on top of each other to form spires.
Cole train knows how to foxtail!
These spires/towers throw off the overall shape of the bud as we’re used to, so they look odd to most people. However, there are also strains that grow bud where all (or at least the vast majority) of the calyces turn into foxtails.
Note that on these plants, every calyx is foxtailing….even the calyces on the underside! It appears to be the same action that’s happening in the “bad” foxtailing picture above, but it’s much more complete.
So, is foxtailing a bad thing? It depends…
I know, I know… no one likes an ‘it depends’ answer. A ‘yes’ or ‘no’ would be a definitive answer and it feels so nice to feel like you know something for sure! Luckily for us as growers, you can learn to tell if the foxtailing you’re seeing is good or bad in just a few minutes! Now you can impress your friends!
Note: That was a trick! Impress your friends with cooking and/or Karate, but tell no one you grow cannabis!
The Two Types of Foxtailing
(Good vs Bad)
Before we go any further, I have to admit that designating one type of foxtailing ‘good’ is a bit misleading. I call it ‘good’ in that it doesn’t provide any positive or negative benefits; ‘good’ foxtailing looks a bit funky but ultimately, it’s purely a cosmetic issue. However, ‘bad foxtailing’ really is a bad thing and comes with consequences…
Being able to tell if the foxtailing you’re experiencing is good or bad is as simple as being able to tell the difference between two foxtailing pictures. Here are two more examples side-by-side:
An easy-to-compare picture with the two types of foxtailing
Let’s start with the one on the left. This type of foxtailing is caused by…
Some strains of cannabis have been bred – by humans and/or mother nature – to form buds where foxtailing is the norm. Although often foxtailing is caused by heat or light stress, when you’re growing a strain that is genetically predisposed to foxtail, the whole bud joins in on the foxtailing action. This makes it so that genetic foxtailing looks more uniform than the other type of foxtailing we’ll review in a minute.Dr. Grinspoon is a weird-looking form of foxtailing, but it makes good cannabis!
The picture to the right is a strain called ‘Dr. Grinspoon’ (named for the esteemed cannabis activist, Dr. Lester Grinspoon). The look of this plant could be considered another manifestation of genetic foxtailing, and it’s important to note that this action happens everywhere on the plant.
Good or Bad? In short, there’s nothing wrong with genetic foxtailing. The fact that it’s genetic means that it was going to do it regardless of whatever specific growing technique is being used. These strains are also capable of containing high amounts of THC, so it doesn’t seem that genetic foxtailing reduces the potency of the plant.
This type of foxtailing is the good type. Again, that only means that it’s good by comparison to bad foxtailing in that it doesn’t cause any negative effects.
Now for the other picture. The other kind of foxtailing (the bad kind) is usually caused by…
The second cause of foxtailing is environmental and it’s usually caused by your lights. If you’ve ever parked a high-powered HPS or LED light (CFLs and T5s aren’t usually strong enough) too close to your cannabis, you might see it grow these odd spires.
A almost pleasant looking, but definitely bad manifestation of foxtails…
A strong foxtail spire caused by light stress!
The fact that the foxtails only seem to appear at the top means this is a bad thing…
What about when buds keep growing new white pistils over and over? This is another version of foxtailing that is caused by heat and light stress. If it’s only happening to the parts of the plant closest to the light, that’s a sign that it’s being caused by stress instead of genetics.
Example of heat and light stress - the extensive new growth at the top of the bud is caused by the grow light being too close!
Good or Bad? Bad! This type of foxtailing is a sign that your buds are getting too much light and/or too much heat! These odd spires can also be accompanied by light bleaching and cooked leaves. Any one of these signs is a message that your lights need to be backed off immediately to halt any further damage. Although light bleaching and burned leaves are obviously damaged, foxtails don’t look damaged so much as they just look weird, so they don’t register as a threat to new growers. Unfortunately, they’re the harbingers of heat damage which means lost potency; if you see this type of foxtails on your buds, you’ve likely already lost potency to heat and now the mission is to lose as little as you possibly can.
Luckily, this type of foxtailing is usually localized, so you’ll only see it in spots where light intensity is super-high. This usually means they’ll be found in a small circle directly under the light, but that small circle gets larger as the light gets closer.
Now with all that being said, plants are weird! It’s totally possible that many of you growers have already seen a plant that makes the ‘bad’ looking foxtails but all over the plant. Or maybe a plant that only grows in spires! The point is that there is bound to be plants that break these rules, but at least until then you’ll know what you’re dealing with. Good luck and happy growing!

@MBgrower no worries
@Seeddog - Thank you so much , I would love to see what it looks like , I’m going to put Bad Foxtail on MJ in the search topic to see what comes up. Very interesting , it definitely has me intrigued .
Thank You again for your reply and sharing your knowledge.
