MrWeeedWorld Guava Runtz Automatic – Week 6 🌱🔥
The girls took the next big step this week and officially moved into a SCROG net. The goal is to keep every branch at the same height so each bud site can receive maximum light and develop into thick, resin-covered colas later on. Honestly, I feel like this strain was specifically bred for this kind of training — she reacts incredibly well to it and looks extremely healthy and comfortable inside the net.
On top of that, the Guava Runtz Automatics officially entered the flowering stage this week. Beautiful little bud sites are starting to appear everywhere and you can already see the huge potential this strain has. The plants look full of energy and seem ready to explode with growth and flower production. 🌸🔥
Yesterday was also a big maintenance day: I defoliated the plants, removed the lower leaves and cleaned away small, unimportant shoots. On top of that, I performed some proper lollipopping to help the plant focus all her energy on the main upper bud sites. Airflow and light penetration are now much better, and everything is perfectly prepared for the upcoming flowering stage.
So far the Guava Runtz Automatic is developing absolutely beautifully and I’m extremely excited to see how she evolves over the next few weeks. If she keeps growing like this, this could turn into an absolute monster run. 🍇🔥
📸 As always, new updates and fresh pictures will be posted every Sunday — stay tuned!

MrWeeedWorld Guava Runtz Automatic – Week 7 / Flower Week 2
My Guava Runtz Automatic is currently also in week 7 and enters flower week 2 together with the Guava Sundae 😁🌱
Unlike some of the other ladies in this run, she stays nice, compact, and bushy — which honestly makes her feel absolutely perfect for a scrog setup. This is exactly how I imagine an ideal scrog plant 🔥
She grows very comfortably, is super easy to control, and spreads her branches exactly the way you want during scrogging. Especially because she is not completely going crazy and trying to take over the entire grow room 😂
I am honestly very impressed with her and I really hope she continues to stay manageable without taking up too much space. This is exactly what makes scrogging fun. No stress, no wild height differences — just controlled, vigorous growth with a beautiful structure 🌱
She is now slowly starting to build her flowers and I am very excited to see how she develops over the next few weeks. So far, she is definitely proving to be an absolute top strain 😁🔥
As always, the next update will be coming next Sunday on GrowDiaries
Feel free to follow me there under Mr.WeeedWorld 👊

MrWeeedWorld Guava Runtz Auto – Wochenbericht
Woche 8 insgesamt • Blütewoche 3
Okay… jetzt wird’s richtig interessant. 😳🔥
Die Guava Runtz Auto zeigt trotz ihrer bisherigen Calcium-/Magnesium-Probleme ein extrem starkes genetisches Potential. Und ehrlich gesagt sieht man auf den aktuellen Bildern bereits sehr deutlich, dass sie sich langsam stabilisiert und wieder richtig Fahrt aufnimmt.
Die Umstellung auf:
💧 Osmosewasser
⚖️ selbst kontrolliertes 3:1 Calcium/Magnesium-Verhältnis
Canna Mono Calcium & Magnesium
…war vermutlich genau der entscheidende Wendepunkt für diesen Grow.
Man erkennt auf den Bildern zwar noch leichte Nachwirkungen des früheren Ungleichgewichts:
etwas hellere Blattbereiche
leicht gestresste ältere Fächerblätter
minimale Unruhe in einzelnen Blattspitzen
ABER:
Der neue Wuchs sieht bereits deutlich gesünder und stabiler aus. Genau DAS ist das Wichtigste. 🔥
Und jetzt kommt der spannende Teil:
Die Pflanze steckt ihre komplette Energie bereits brutal in die Blütenproduktion.
Was sofort auffällt:
❄️ Sehr frühe Harzbildung auf den Sugarleaves
🌸 Viele gleichmäßig entwickelte Budsites
🌿 Wunderschöne offene Struktur
💪 Kräftige Verzweigungen
🔥 Sehr aggressive Blütenentwicklung für Woche 3
Die Colas beginnen bereits schön zu stacken und man sieht jetzt schon diesen typischen FastBuds-Style:
lange spearartige Buds mit massivem Frost-Potential.
Besonders beeindruckend:
Trotz der vorherigen Probleme hat die Pflanze ein unglaublich gleichmäßiges Dach entwickelt. Das bedeutet:
hervorragende Lichtverteilung
viele gleich starke Tops
enormes Potential für richtig dicke Blüten später
Und die Trichome… 😳
Für Blütewoche 3 ist da bereits überraschend viel Frost auf den Zuckerblättern sichtbar. Die Guava Runtz scheint genetisch wirklich komplett auf Harzproduktion programmiert zu sein.
Meine Einschätzung:
Du hast das Problem wahrscheinlich genau rechtzeitig abgefangen.
Mit deinem neuen Wasser-Setup könnte die Pflanze jetzt endlich ihr eigentliches Potential entfalten.
Das Schöne an Cannabis:
Neue gesunde Entwicklung ist wichtiger als alte beschädigte Blätter.
Und genau das sieht man hier aktuell sehr deutlich.
Aktueller Status:
🌱 Erholt sich sichtbar
⚖️ Neues Wasser-Setup scheint zu funktionieren
❄️ Frühe starke Harzbildung
🌸 Viele gleichmäßige Budsites
💪 Sehr gute Struktur
🔥 Hohes Frost- und Ertragspotential
Wenn sie jetzt in den nächsten 2–3 Wochen richtig in die Massenbildung geht, könnte das trotz des holprigen Starts noch ein absolut brutaler Run werden. 🍇🔥
Und ganz ehrlich…
die Kombination aus:
roten Blattstielen
hellgrünem Frost-Look
langen spearartigen Colas
…sieht jetzt schon verdammt sexy aus. 😎
JEDEN SONNTAG neue Berichte!

Guava Runtz Auto – Weekly Report
Week 8 Overall • Flowering Week 3
Okay… now things are getting REALLY interesting. 😳🔥
Despite the earlier calcium/magnesium issues, this Guava Runtz Auto is already showing extremely strong genetic potential. And honestly, from the current photos you can clearly see that she is slowly stabilizing and getting back into full growth mode.
Switching to:
💧 reverse osmosis water
⚖️ a self-controlled 3:1 calcium/magnesium ratio
Canna Mono Calcium & Magnesium
…was probably the turning point for this grow.
You can still notice some remaining signs from the previous imbalance:
slightly lighter leaf areas
mildly stressed older fan leaves
small irregularities on some leaf tips
BUT:
The new growth already looks much healthier and more stable. And THAT is what really matters. 🔥
Now comes the exciting part:
The plant is already throwing huge amounts of energy into flower production.
Immediate observations:
❄️ Very early resin production on the sugar leaves
🌸 Many evenly developed budsites
🌿 Beautiful open structure
💪 Strong branching
🔥 Very aggressive flower development for week 3
The colas are already starting to stack nicely and you can clearly see that classic FastBuds style:
long spear-shaped buds with massive frost potential.
What’s especially impressive:
Despite the earlier problems, the plant developed a very even canopy. That means:
excellent light distribution
many equally strong tops
huge potential for thick flowers later on
And the trichomes… 😳
For flowering week 3 there is already surprisingly heavy frost visible on the sugar leaves. This Guava Runtz seems genetically programmed for resin production.
My impression:
You probably corrected the issue at exactly the right time.
With your new water setup, the plant may finally be able to unleash her true potential.
That’s the beautiful thing about cannabis:
Healthy new growth matters more than old damaged leaves.
And that’s exactly what we can clearly see here now.
Current Status:
🌱 Clearly recovering
⚖️ New water setup seems to work
❄️ Early heavy resin production
🌸 Many even budsites
💪 Very good structure
🔥 Huge frost and yield potential
If she really starts packing on flower mass over the next 2–3 weeks, this could still become an absolutely brutal run despite the rough start. 🍇🔥
And honestly…
the combination of:
red leaf stems
light frosty green tones
long spear-shaped colas
…already looks insanely sexy. 😎

MrWeeedWorld The Guava Runtz is looking fantastic this week. After overcoming the earlier calcium and magnesium issues, she has bounced back impressively and is now showing strong and healthy development throughout the entire canopy.
One of the most noticeable features is her open structure, allowing excellent light penetration into the lower flowering sites. What initially appeared to be longer internodal spacing is now proving beneficial, as nearly every bud site receives direct light exposure and develops evenly.
Trichome production is steadily increasing. The sugar leaves are beginning to sparkle with resin, giving the buds an increasingly frosty appearance. While the flowers are still building density, their shape and formation already indicate excellent potential for the coming weeks.
Below the SCROG net, the plant remains exceptionally clean thanks to the earlier lollipopping work. This allows the plant to focus all available energy on the upper flower sites, resulting in efficient bud production across the canopy.
The strong stems and branch structure easily support the current flower weight and should continue handling the upcoming bulking phase without issue. Combined with the RDWC system, high light intensity and supplemental CO₂, the Guava Runtz is perfectly positioned for explosive flower growth during the next few weeks.
Weekly Highlights:
🌱 Excellent recovery from previous Cal/Mag issues
❄️ Increasing trichome coverage across the plant
💪 Strong branch structure and SCROG performance
☀️ Outstanding light penetration throughout the canopy
🍈 Early signs of the famous fruity Guava terpene profile

MrWeeedWorld The Guava Runtz continues to develop into one of the most interesting plants of this run. While it initially focused on structure and branching in the first weeks of flowering, it is now fully concentrating its energy on flower production.
The main colas have noticeably gained volume within a week. Particularly impressive is the even distribution of buds across the entire plant. Thanks to the open structure and well-executed SCROG, even the lower flower sites receive sufficient light and are developing almost at the level of the main stems.
Another highlight of this week is the first violet and dark red color accents within the flowers. These are starting to spread between the calyxes and sugar leaves, already giving the plant an extraordinary look. Along with the increasingly dense layer of trichomes, a very attractive appearance is emerging.
Resin production is now picking up significantly. The sugar leaves are completely covered with trichomes and are already visibly reflecting light. Especially the close-up shots show that the plant is now beginning to fully express its genetic strength.
Under the canopy, the Guava Runtz continues to present itself exemplary. The strong main branches effortlessly support the increasing flower weight, and airflow within the canopy remains excellent. The previously performed lollipopping is now paying off significantly.
The slightly lightened older fan leaves indicate that the plant is mobilizing nutrients more intensively in the middle of the flowering phase. Overall, it appears vital, healthy, and fully focused on flower production.
Weekly Summary
🍈 Significantly more flower mass than in week 9
❄️ Strong increase in resin production
💜 First violet hues becoming visible
🌿 Very good light distribution through the open SCROG
💪 Strong branching effortlessly supports flower weight
🔥 Currently developing into a true frost machine
📅 New updates are posted every Sunday on GrowDiaries! Check back regularly and follow the Guava Runtz on its journey to harvest. 🌱

MrWeeedWorld The Guava Runtz continues to develop excellently and is clearly showing why it belongs to my favorites this run. The buds are visibly increasing in size and density week by week, while the resin production keeps rising.
Especially impressive is the plant's recovery after the challenges of the past weeks. Since optimizing the calcium and magnesium supply, it has returned to full strength and is putting all its energy into developing its flowers.
The buds are increasingly becoming denser and developing a beautiful mix of bright orange pistils, purple color accents, and a thick layer of sparkling trichomes. Every glance at the colas reveals new details and even more frost.
Thanks to the SCROG training, a very even plant structure has been established. Almost all flowering sites receive optimal light conditions, which is now reflected in an impressive number of evenly developed colas. This is exactly the result I envisioned.
The scent is also becoming more intense day by day. Sweet tropical notes meet creamy and fruity aromas, already hinting at the flavor experience that awaits me later.
Guava Runtz is now in the final stretch. In the coming weeks, it will significantly increase in mass and resin. I’m looking forward to seeing what potential this beautiful lady will unfold by harvest time.
Thank you for stopping by and your support! 💚
🌱 Happy Growing! 🌱

MrWeeedWorld Week 12 – Flower Week 7 🍇❄️
Guava Runtz is officially entering the final stretch. Compared to last week, the buds have noticeably increased in density and size. The calyxes continue to swell and the colas are getting heavier every day.
The resin production is absolutely outstanding. Even the sugar leaves are now completely covered in trichomes, giving the plant an incredibly frosty appearance. Beautiful colors are beginning to emerge throughout the flowers, adding even more bag appeal.
After dealing with some calcium and magnesium issues earlier in flower, she has recovered remarkably well and is now putting all of her energy into bud production. The flowers are dense, resinous and developing evenly across the entire plant.
Many pistils have already darkened, while a few fresh white hairs continue to appear. This indicates that the plant is still adding weight and refining her final quality before harvest.
The final weeks are always my favorite part of the grow and Guava Runtz is delivering everything I hoped for. Frosty buds, strong structure and an aroma that becomes more intense every single day.
Just a little more patience until harvest day arrives. 🍇🔥

MrWeeedWorld This week, my Guava Runtz is impressively showing why it’s one of my absolute favorites. The buds are getting denser by the day, and each cola is now completely covered in a thick layer of sparkling trichomes. The beautiful purple hues are becoming more pronounced among the frosty buds.
Most of the pistils have taken on a rich orange color, while only a few fresh white hairs are still visible. The calyxes continue to swell, and the buds are gaining weight daily.
The canopy is developing just as I wanted. Some leaves are starting to show slight signs of age – totally normal for this late flowering phase, as the plant is putting all its energy into bud production.
I’m really excited about how evenly the entire canopy has developed. Thanks to the training, nearly all bud sites are getting optimal light conditions, which is now paying off with thick, compact, and extremely resinous buds.
Slowly, the Guava Runtz is heading into the home stretch, and I’m already super excited to harvest it soon. If the aroma and effect live up to the looks, this will definitely be a highlight of my Fast Buds run.
Today was finally harvest day for my Guava Runtz. ️
After weeks of care and attention, she reached the finish line. She produced a wet weight of 200 grams. While she wasn't the highest-yielding plant in this run, she definitely made up for it with her outstanding quality.
The buds remained medium-sized and nicely compact, rather than turning into huge colas. What she may have lacked in overall yield, she more than compensated for with her incredible appearance. Every flower is coated in a thick blanket of shimmering trichomes, giving her that beautiful frosty look that makes the Guava genetics so special. Combined with the deep orange pistils, she truly looks stunning.
Immediately after harvest, all the buds were placed into my VIVOSUN VCure, where they'll dry under controlled conditions before automatically transitioning into the curing process. I'm really looking forward to seeing how the terpene profile develops over the coming days. Even during harvest, she released a delicious aroma of sweet tropical fruits with creamy undertones—exactly what I was hoping for from this strain.
Not every cultivar needs to produce monster yields. For me, quality always comes before quantity, and that's exactly where the Guava Runtz shines. Now it's time to be patient and let the curing process unlock her full potential.
A huge thank you to 42FastBuds for creating such a beautiful genetic. ️

MrWeeedWorld The Guava Runtz may not have been a yield machine, but it delivered exactly what I wish for from high-quality genetics: beautifully frosted buds, a great structure, and a scent that makes you crave more even during the harvest. Now I'm looking forward to seeing how it fully unfolds its flavors and taste after the VCure. Quality always beats quantity for me in the end. 💚
Happy harvest! 😍
I did a genetic cross project and named it OG Cream. I'd be happy if you check it out. 👽🙏🔥
