P91 x Jack the Ripper, Tester - Irie Genetics - Fall 2023

[ExNavyInSTL]

Back with another grow journal.

This time I am testing 4 each of P91 crossed with Jack the Ripper (P91 x JTR) for Rasta Jeff of Irie Genetics.

These are regular seeds, but I have Sex Tests at the ready from Rimrock Analytics.

---

Lately, I seemed to have settled on Irie and Brothers Grimm for my go-to breeders.

I didn't do my Grow Diary here, but I'm currently finishing up a garden with:

• Arise x Golden Goat - Tester from Irie Genetics
• Puck Yes - Brothers Grimm
• Mota Hari - Brothers Grimm
• Cinderella Purple - Brothers Grimm
• Spartan Sour Diesel - by Welcome to the Grow Tent (WTTGT)

I'll share a few of the ending photos here, but mostly I will focus on the P91 x JTR.

I'm also growing Cinderella 99 and Genius Juice from Brothers Grim, but I will start separate journals for them.

As far as nutrients go ... I make my own.

This previous grow was my first time going from seed to harvest using my own nutrients. I think it went well.

---

After a lot of research and comparison, I settled on the following "elemental" ppm's for each nutrient as follows:

---

I made no specific elemental changes for Veg or Flower. However, I did lower my recipe from 2.2 E.C. to about 1.6 E.C. towards the end of flower. I tend to use bottom-watering in SIP Buckets or AutoPots. So, there is nutrient accumulation in the lower part of the pot anyway.

My guess is that I could probably switch to water pretty early and there would be plenty to eat until the end.

Another guess is that this nutrient build-up could serve as a battery if the plant wants more P or K in the flower section. But, I don't manually beef anything up and I don't lower nitrogen specifically.

Note: The "estimated" E.C. is 1.799 (+/- 10%) if I follow to a "t". However, as I said above, I dilute to about 2.2 E.C. and taper down to 1.6 or so.

Because I grow in coco, I do add 1 - 2 ml / gallon of cal/mag. I do this as a precaution and because of coco paranoia. : )

---

I don't flush for flavor or any of that.

I just run them until the trichomes are mostly cloudy with a hint of amber.

I do use some supplements, but that list is dwindling as I use them up.

I mix up my nutrients 1 concentrated liter at a time and they are concentrated 200:1.

This works out to 5 ml / liter. I round it to 19 ml / gallon.

The following are my ingredient lists and quantities for Part A & Part B.

While these plants in this Grow Diary are boring little seedlings, here are some glamor shots of my current plants waiting for harvest.

I do apologize if the Mota Hari and Spartan Sour Diesel pics seem darker than they should be. I have done all sorts of changes and sometimes they look right, and other times they look dark.

I've grown JTR few times over the years. A older strain, but it's a favorite of mine. It was originally from subcool

I like the Subcool angle. I’ve only been growing for two years, but I hear different breeders always honoring him.

Day 10 - Update

I have one droopy one. I suspect I got the coco too wet or too hot (EC).

In the first week, they received about 0.6 EV
Now they are getting 1.1 EC

I'll hold there for a while.

Mostly soaking from the bottom. Although I am using a large syringe to do more control watering from the top.

Stoked to see more of your amazing photography!

The early stuff is to document their growth with iPhone, etc. The Glamour Shots come later.

I have an underachiever ... my guess is from too much moisture in the coco.

 

[Chrondocious]

Ive grown lemon jeffery. Unfortunately lost my cut. Irie has some fire genetics.

 

[ExNavyInSTL]

Day 14 - End of Week 2

I have one plant that is having issues. It looks like early Ca issues, but hard to tell at this point.
2 plants are going strong.

Droopy is still Droop'n and lagging, but coming along.

The two on the right in the 4 x plants shots are doing fine.

Sex Test Day - Day 16

I took tissue samples today and ran them up to the post office.

 

[ExNavyInSTL]

By the way -- Regarding Sex Testing

I used RimRock Analytical for these tests. I've great service from both them and Farmer Freeman.

Day 18 - Check In

Very happy so far. Leaves are finally turning a nice green, not as splotchy.

---

• I've moved them up to 2.0 EC. They needed it.
• They get fed everyday since I am in coco.
• I top & bottom feed now. Then I tilt the pots and drain off the excess.
• I let them set as is for a few hours, then I set each one on a stack of paper towels.
• By doing this it draws out the old moisture and nutrients.
• Then I repeat the next day.

---

• They are getting about 400 ppfd for 24 hours.
• Once I move them into their tent and put in 6 gallon pots, I'll switch to 18/6.
• My guess is a 6-week veg.

---

I'm likely to throw in my two Brothers Grimm Seedlings into this Grow Diary. I didn't intend to, but I already post enough. : )

Day 19 - Fast Growing Phase

Everyone is happy and healthy. I love this phase where dramatic changes can happen by the day.

Day 19 Observation:

• I've posted that I have 2 of 4 that are grower much faster (#2 & #4).
• However, I noticed today that the fast growers have purpling on the branches (not the stem).
• The shorty plants are a normal looking green.
• I don't think it is a nutrient thing, because they are fed well.
• What will be interesting is when the sex tests come back if the taller plants are the males.

Day 22 - Update

Strange lack of nodal growth on #4 compared to the others.

Day 24 - Leaf Issues
​

• Burnt Tips (feed too hot - lowered to 1.5 EC)​
• Leaf Curling (skipped watering)​

Note: I grow in coco, so I water and feed every day.

To protect the roots, I then place an abundance of paper towels under the pots to draw excess water from the coco. So, they are never sitting in soaking wet soil (for long).

Soon, they will get transferred to their AutoPots to feed from the bottom. It will take a couple of weeks of hand watering to let the moisture and feed permeate the pot and for the roots to stretch out to the nutrients.

It's Homecoming ...

Since I finally harvested the last crop, I gave the tent a good scrub down and then placed in all of the AutoPots.

I'm letting them "water/nutrient" in overnight before I re-pot.

You still have to water them in for a couple of weeks before the system is up and running.
