Salutations and welcome good peeps. ‘Probs wit da Purps’ simply means issues that come with a lot of purple cannabis genetics. They’re not major, usually, but not knowing how to handle it can result in subpar purple plants, and subpar purple buds. Sometimes big missed opportunities.
I friggin’ love purple plants when they are grown well, also, dried and cured well. Purple plants have a kind of flavoring all their own. It’s close to grape, and purple plants when done well, are crazy sublime buds. They not only look super impressive, but they smell and taste super impressive.
There are few things I have learned over the decades growing cannabis regarding the purple plants, and how to give them a little extra help. Most cannabis plants will go pretty purple in very cold weather (nights). But a true purple one will get almost black in that same cold it gets so purple. Unfortunately, purple cannabis plants aren’t usually what I would call hearty, minor issues can kill them extra fast. Parasites also tend to favor them.
Purple Cannabis Genetics and Potency
Here’s something I have noticed about most purple cannabis genetics. Something like 75% of the time, if I find a wicked purple phenotype amongst siblings, it also has less resin production than its siblings. So, when selecting, you need to be on the lookout for this common twist.
On the other side of the coin, around 15% of the time they have great resin production. Around 10% of the time they have insane resin production. This assumes the genetics you are growing have high resin production potential, in general. Purps can appear in any generation of any cannabis. They are often culled (killed) at an early age, mistaken for weak plants. While they have some weaknesses, they are mild usually, and can be dealt with easily once you know how.
Purple Leaves, Calyxes, Pistils, and Stems
Pistils, (bud hairs) are very rarely purple, but I have seen it a few times. Whenever I see pinkish pistils, I count that as a purple expression. Though most purple plants have darker red pistils, I have seen ones before with pretty bright orange pistils. That shit looked like it was from outer space.
Stems, will often stripe purple due to potassium and/or phosphorous issues. But true purple plants almost always have purple or red striped stems normally, so ’t’s not a sign of a deficiency. Stems will also stripe purple during very cold nights. It’s rough for plants to process P and K when it is very cold.
Leaves, and calyxes sometimes are both purple, sometimes just one or the other. I far prefer purple calyxes, myself, because it really bestows that “purple grape-ish flavor” into the buds proper. But cannabis plants that have dark purple leaves and lime green calyxes produce buds that are beyond impressive looking. I have harvested buds so purple that even the hash (sifted) made from it had a distinctive purplish tone.
Probs wit da Purps, They Normally Need a Little Special Attention to Rock Them
I recently visited a friend about to cull a few plants during selection, looking for the best females to clone from a batch of sibling sprouts from the same variety. I pointed out he was about to snuff out his purple plants. He had no idea … Now he does 😉
Try and keep your nighttime temps above 58 degrees F. This really helps out any purple plants in the mix and is all good with other varieties. Sometimes when I have especially purple plants, I make them a special soil mix on the spot before transplanting, simply adding (10-15% cut) vermiculite. Vermiculite is a pH neutral soil amendment which does what the purps need at the time, and that is a pH that doesn’t drop too far below 6.8 pH. 90% of the time this vermiculite blend will almost always handle probs wit da purps.
I used the vermiculite method on these clones (just transplanted) in their soil mix to help them over the purple slump. Purple genetics need to have the maximum amount of K available to them in order not to get wonky. The pH dictates this to a high degree, as do nighttime temps. Never try and slam in K via liquids or extracts. This will only further bone you.
Now, my soil (TLO soil) handles the purps and any other variety well, however, when I am planting freshly (aero) rooted clones for their first time in soil, I use Ocean Forest soil (Fox Farm) with a little bit of earthworm castings. My TLO soil is way too powerful for these. This is when my purple cannabis genetics really show their weaknesses. It’s just due to pH going a tad too low is all. It could also be a shortage of Ca, K, and/or P, but it is way more likely it’s an availability issue due to pH rather than an actual shortage.
For a super-fast fix once into soil, bottled spring water works well. Using some dolomite lime bubbled water works especially well, adjust the PPM of this water to around 65 PPM (60-67 PPM). In those photos above you can see how the purple cannabis genetics look when they have issues.
Okay then, that’s it for today. I hope I drove the point home regarding cannabis genetic selecting. Many times, newer breeders mistake exotic expressions as weaknesses. Purple cannabis genetics are fairly obvious out of the gate if you are looking. The leaf veins, petioles, and stems are normally purple most of the time. Kingdom Organic Seeds has a lot of purple leaning genetics, so stop by and have a looksee.
The very best way to select your genetic winners is to make clones of them and flower them. Save the clones, and keep your very favorites. As you become savvier as a breeder, you will be able to tell more and more things regarding your plant expressions, much earlier on. This reduces your work load considerably. Nobody I have ever seen just magically has this ability. You can get lucky for sure and luck is definitely on the table always. But time in the trenches is what you need. Patience Grasshopper.
I loves me some purple doobies. My very favorite papers to roll up purple weeds in are the clear type of papers. In my opinion, the absolute smoothest smoking papers by a lot.

- REvski 😊
I'm The Rev, and I have been with SKUNK for about a decade now. I hail from Southern California, spent mucho time in Northern California, and now reside in Southern Oregon; always coastal. I am an all natural style cannabis grower and I have written a couple books on the subject - check out True Living Organics 2nd Edition on Amazon - I have been growing for over 45 years, and I have been breeding cannabis for over 30 years. Check out kingdomorganicseeds.com to see some exotic selections. Growing connoisseur cannabis is what I teach mostly, growing it in living soil without using liquid organic nutrients to feed the plant. I am also a highly skilled synthetics grower, hydroponics, aeroponics, DWC/SWC/NFT, Ebb and Flow, and soilless, but I cringe when smoking synthetic grown herbs, so for the last 15 years or so I preach the artisan style of all natural growing, specializing in container growing. Cheers and welcome aboard.
