How much longer for this Deep Purple to go to achieve what I want??

I've grown 4 Deep Purple ladies prior to this one (Got a 5/5 female ratio), so this is my last girl standing out of the 5-pack. She isn't the keeper pheno I found (Which reeked of Grape Big League Chew, Wonderful Grape Heaven), but she is my 2nd favorite pheno, which I've determined to be a more Urkle dominant pheno. I noticed that the 3rd pheno was dominated by Querkle traits, with that just sour rotten cherry type of smell.

I actually ended up liking the Urkle dominant pheno a little bit better (the one I have now, posting pictures of). She seems to have a sweeter smell, less putrid. It also seems like she takes a lot longer to finish, however, and shows far less purple hues than the Querkle dominant pheno does.

Here are the shots of the Urkle dominant Deep Purple I'm finishing right now. I am planning on letter her go about 2 weeks longer, but I am very interested to know what you guys think. I don't have a day count for her, sorry about that. I haven't cut a sample to check under the Veho yet, just because I know she isn't ready.

This is the kicker:

I want to max out CBD and CBN levels with this grow. THC content is really meaningless to me regarding this specific strain. If I were shooting for highest THC content, I would take her down within the next 5 days.

I'm trying to get some fade in her leaves, she is still dark green all the way down to the first leaves, the starter leaves. I've been heavily watering with nice distilled water for the last week.


Here are the shots guys, and all input is much appreciated!!!

How much longer should I let her go to maximize CBD and CBN levels, without compromising too much of the THC to work in correlation with the cannabinoids (CBD and CBN) that I am after???

Still quite a few white hairs. I'd say 2 more weeks. Looking good!

no scope or loupe to check the trichs?

the thc profile isnt largely changable by harvest time its more strain specific but from what i know you want to harvest a bit late for high cbd content however keep in mind that by doing this you are degrading thc into the cbd (someone correct me if im off on this but im nearly possitive my memory is serving me right)...so i can harvest two different strains next to each other and i can do the high cbd plant a little early and the low cbd plant nice and late and it still wont touch the levels in the strain bred for cbd and then it will also have a lower thc than it would have..also in the future its alot easier to give advice on harvest time if we have a shot of the whole plant but that does look flike it can take another couple weeks from what i can see

THC actually degrades into CBN.

CBD is a completely different cannabinoid that is synthesized alongside THC. CBD also degrades into CBN, but at a much later stage.

You are correct in saying that CBD develops in the late stages of flowering.

I have a Veho microscope, I just didn't want to cut a sample when I know it isn't ready, and the microscope is powered by USB, so I can't really take it in there and focus on the live plant, it would be too hard to focus like that.

ok i had those two confused then...still though i dont think it is largely affectable only to the limits of the strain, strains bred for cbd will always hit higher levels...heres the test results for querkle..low cbd http://analytical360.com/m/expired/31149

That is only one phenotype, and similarly one chemotype.

I noticed a significant difference in the chemotypes of my Querkle dominant Deep Purple and my Urkle dominant Deep Purple.

The Querkle dominant Deep Purple was much higher in THC and much lower in CBD.

The Urkle dominant pheno, however, was much lower in THC, and packed a heavy heavy body punch. I attribute it to high CBD levels.

Don't forget, phenotype variances often mean chemotype variances as well...

snip a tiny piece of sugar leaf from the top and scope it

Should I clip it from the top, or from several different parts of the plant. I usually take samples from the middle to check. Also I've noticed that sugar leaf trichomes are often times more mature than the trichomes on the bud matter.

I'm starting to get a really good feel for plants without even using my Veho scope. There is a grower I follow on Youtube that goes by the name Mr. Spliff, and he takes his plants so far into flowering it's ridiculous. It has really inspired me to start pushing the limits and see what kind of resin and cannabinoid profiles I can start getting out of plants.

I think I'm going to leave this Deep Purple for AT LEAST 2 more weeks, maybe even 3 or 4. I'm just going to be keeping a close eye out for nanners, because she's in there with like 10 other girls at week 3. Yikes

i take a little snip from various spots, just a tiny bit from the top of the bud area works for me. good luck

What I'm truly wondering is...At what point are CBD levels maximized in most indicas. If I had to guess, it is a little past peak maturity, when no clear trichomes are present.

I do know that amber trichomes signal the degradation of THC and CBD into CBN, and also that THC production is at its peak when the trichomes are mostly cloudy and slightly clear. I've just never heard any good info regarding peak CBD levels. Does anybody know???

i think your right maybe a little past peak but that goes back to what im trying to articulate..i think you may raise the cbd slightly by waiting but also slightly degrade thc and the question is is the overall profile and high (or pain relief if thats what your going for here) better or are you better off just harvesting at peak because thats the profile the strain was meant to have..i think the best experiment to do here would be to harvest a branch on time with the others (i understand you may be too late to do this this time) and then let the plant go longer and when its allll cured take a first time of the day toke of the peak branch and the next morning of the late branch and see which is better for you personally. i still say that while you can possibly affect these levels the best route is to check what profile a certain strain usually has and shop for a high cbd strain because you cant take a low cbd strain and get high cbd you can only affect this by so much....basically what im trying to say is you can harvest a grape early and it will taste sour like a lemon but then why not just grow lemons?!
