First time seed production Questions

I am trying my hand at seed production. I'm not advanced enough to worry about cubbing and producing breeder strains YET. Basically, just trying to experiment. I've had a perpetual for about 2 years now and want to preserve some of the strains in my collection and make a few.

I've crossed the same Querkle male with:

1. Agent Orange phenotype 1
2. Agent Orange pheno type 2
3. Royal Queen Special Kush #1
4. Royal Queen Blue Mystic
5. Querkel

I'm 8 weeks in and the seed pods are very swollen and getting mature. The buds on the plant, however, are not swelling like normal. I could expect this due to the energy the plant has to put into seed production but it doesn't seem normal. The buds look like they are about 4-5 weeks stage. I'm not sure how the plants should develope but they all look imature and stunted a bit at this stage. I do have some calcium difficiencies that are being addressed. Also, I have just switched nutrients to see how the botanicare CNS17 works. Don't think I like it at all coming from the FF product line.

Does the development of a seed producing plant take a longer cycle? When should I havest if so? Same time I would harvest the Sensimilla?

Do seed producing plants require a diffrent feeding cycle or nutrients? What extra addatives should I use. The Querkels started out very fast but have been maturing very slow after week 5.

Not sure on all this, but if harvesting for seeds, wait till they are mature, you will see the calyxes splitting open and a brown mature seed will be exposed. If unsure, harvest a single bud, dry it out and test the seeds.

I have never noticed a marked difference when pollinating a select branch on a plant over a plant that wasn't selectively breed. Each strain seems to act a bit different on the buds which have been pollinated but I have never seen it affect the other part of the plant or other buds. Producing a seeds on 1 branch is a great and effective way of enjoying the best of both worlds. Seeing differences in your clones or one plant over another is pretty common. Strange plant to grow and find that the smallest differences in something during this grow over other grows effect the plant. Maybe one time a strong smell and then a few times without smell, just one of those things I reckon. As far needing anything different to produce the seeds, not at all they will do fine.
I hope you have lots of fun, it keeps me entertained for hours each day.
