nutes or genetics

So some background...

Father of this cross: View attachment 1094822. Chosen for being very purple during veg & flower. I have grown this male several times from clone and continue to use it for my breeding work.
Mother of this cross is a cut of sour diesel elite. I have also grown this plant several times and have not had this trait exhibited.

I put down 50 seeds, 30 sprouted and were transplanted into soil. They were started in AN jiffy cubes.

Shortly thereafter they were transplanted into a soil mixture that I made myself. It is very light and fluffy, holds moisture & air very well.

Contains:

Master Nursery - Gardners Gold Organic Blend
A rich, all natural blend of finely screened, composted fir bark fines, worm castings, real topsoil, redwood peat moss, chicken manure, and sand. pH balanced with dolomite and oyster shell limes.
Master Nursery - Black Forest Organic Compost
A blend of forest humus (redwood and fir bark) composted and screened to a uniform 1/4" minus size. Fortified with .5% nitrogen and .08% Iron.
Perlite - both large & small
Vermiculite
Coco
Oregonism XL

My nutrient line is Humboldt Nutrients - I'm using the Master A/B line as well as their full compliment of additives. I am currently about 500ppm. I feed with nutes, rest, feed with a compost tea, rest, feed with nutes, rest, compost tea, etc...

I use RO water to make both the compost tea as well as my nutrient solution.

On a fresh batch of soil, RO water in = apx 1000ppms on the way out.
pH of RO going in = n/a pH of water coming out = 6.7 - measured with digital pen

I have some damage on the very bottom leaves that all get trimmed off anyways by the time i transplant. But that isn't what my question is about. Of the 30 plants, 8 of them have been transplanted and cycled to outdoor for their last week of veg prior to flowering. Of the remaining 22, 8 have been topped and will go into flower apx 2 weeks from now. Of the remaining 14, 3 have been selected for breeding. At this point I don't know what is male or female, however, because of the continued work with the genetics, i've got a good feeling of male and female. The last 11 will probably be given away.

From the time the 3rd node began growing to when the 6th node started growing the pH of the compost tea as well as the nutrient solution was brought down to 6.3 forcefully (there is no pH modification recommended by HN), the NPK ratio was modified to 3:2:1 and a supplement of actinic light (apx 420nm) was used. All of this was done to promote a higher female to male ratio.

After that week, all things went back to normal. (Normal being under eight 4 foot t5's or four 4 foot 96W PC's, Nutrient back to normal ratio as per manufacturer)View attachment 1094825View attachment 1094824

The trait showed up about a week ago and is getting more and more evident daily as it travels from the top of the plant to the bottom. I have purple stems, purple stalk, and on only 1 of the plants purple veins. As i mentioned, the male used for my breeding was selected because of how much purple it contained. The female siblings of the male used also have purple traits but only in the leaves and it arrives late during flowering prior to flusing.

At this point i've not changed a thing in what i do. Other plants in the same soil mixture are not exhibiting any purpling of the stems or stalk as of yet, however, they are about 2 weeks behind. I don't see any signs of nutrient deficiency. I'm not an expert though...

Any thoughts?

Is this the genetic trait i have been trying to propegate coming out?

Cool project man, cool indeed. :cool:


I'll also say that it's probably just the genetics of the plant, rather than a deficiency starting. In my experience, 'purpling' from being deficient, has more of a reddish tint, than that purple color of your plant.
