AlpenZilla Welcome!
This grow wasn't really planned, but I just felt like starting one again! ๐
Week 0:
The White Widow seeds were germinated in Jiffys using osmotic water (EC 0.15, pH 6.7).
After around 7 days, they were transplanted into 1L pots filled with BioBizz Light Mix (EC 0.4, pH 6.7).
Later on, theyโll move into 15L final pots.

AlpenZilla Week 1 - Veg Stage starts (VT1 - VT8)
VT1:
The official count starts today.
They stretched a little too much, so I increased the light intensity by one dimmer level.
Watered for the first time with 50ml (pH 6.4 / EC 0.4).
VPD was between 0.6 - 0.7.
VT4:
Everything is going well so far.
Increased watering to 150ml, still at EC 0.4.
Next watering will be with 250ml and EC 0.6.
VT6:
I actually wanted to keep this report a bit more relaxed, but somehow Iโm documenting more than ever. ๐ค
Watered today with 250ml (EC 0.6 / pH 6.3) using the adjusted Advanced Nutrients schedule for Veg 1 + 2.
VT8 - End of Veg Week 1:
The first week of veg is done.
Everything went according to plan.
They are starting to drink more now.
VPD has been raised to 0.8 and will be increased to 0.9 over the course of the week.

AlpenZilla Week 2 โ Day 14 (Veg)
Around day 12, White Widow #1 started to show early signs of deficiency.
EC was 0.9 at the time โ likely too low for her current stage.
Smaller plants in the grow showed no symptoms, which supports the idea that the larger ones needed more nutrition.
To correct this, I increased feeding: base EC 0.4 plus full nutrients, total EC 1.3.
The symptoms did not get worse after that, but her leaf color still remains slightly lighter than the rest.
She was also moved into the final tent this week.
During the move, I removed the first node pair to promote better structure.
Transplant into a 15L fabric pot is planned for next week.

AlpenZilla Week 3 โ Day 22 (Veg)
White Widow #1 was topped this week and received her first round of light LST ๐ฟโ๏ธ
She also moved into a 15L fabric pot and was watered with 2.5L ๐ง
Unfortunately, even an EC of 0.8โ0.9 was too much for her ๐
She showed signs of overfeeding, likely from too much nitrogen.
To reduce stress, I lowered the DLI to 27 โ๏ธ
Right now, sheโs my main concern โ not in great shape, but slowly recovering ๐ช
Next watering will be with a reduced EC of around 0.5 to help her bounce back ๐ฑ
Looking ahead to Week 4:
๐น Watering volume will be increased to 4โ5L depending on need
๐น I checked root development by opening the fabric pots โ looking promising! ๐ง
๐น LST will continue, and some larger fan leaves might be removed to improve airflow and light penetration ๐ฌ๏ธโ๏ธ

AlpenZilla Week 4 โ Day 30 (Transition)
Where do I even beginโฆ ๐
White Widow #1 officially started flowering this week (Day 0 of bloom) โ but not without drama ๐ต
She managed to break off four of her own tops due to LST mistakes or weak stems.
But hereโs the crazy part:
๐ Two of the broken shoots actually reattached themselves and continued growing โ even though they were hanging by just a 1 mm strand! ๐ช๐ฑ
The photos show it clearly: sometimes it's worth trying, even when it looks hopeless.
Despite the rough week, she's holding up and is now officially in the 12/12 cycle.
Stretch is coming โ letโs see what sheโs got in her! ๐ฟ๐

White Widow #1 is looking strong this week ๐ช
A bit of supercropping here and there, and sheโs throwing out one massive fan leaf after another ๐
She officially passed the 50 cm mark and is now fully into stretch mode ๐ฟ๐
Things are getting crowded in the tent ๐
But overall, sheโs handling the transition to bloom really well and shows no major issues so far.
Looking forward to seeing how much taller sheโll get in the coming days!

AlpenZilla Week 6 โ Day 44 (Flower Day 14)
๐ Recap
This week, White Widow received a full lollipopping and defoliation session โ๏ธ
She handled it really well โ no signs of stress or hermies so far โ
Everything looks stable and on track!
๐ง I also started mixing my osmotic water at a 10:1 ratio with tap water.
This gives me a more stable pH and a starting EC of 0.08 โ ideal for nutrient mixing.
๐ก Lighting Update
White Widow is currently under the Kingbrite P55 320W.
I increased the intensity slightly, and her DLI now reaches 78 over 24h, which equals 39 per 12h ๐
She seems to enjoy the boost โ no signs of light stress, just healthy growth!
๐ฟ Plant Status โ White Widow
๐ Height: 73 cm (+23 cm this week)
๐ง Drain pH: 5.7 โ despite feeding with pH 6.6
โ๏ธ EC: 1.6, currently running at 75% of the feeding schedule
โ No issues at all โ she's handling the lower drain pH like a champ!

AlpenZilla Week 7 โ Day 51 (Flower Day 21)
๐ Recap
A calm and steady week.
Mostly just watering, observing, and occasionally removing a leaf or two ๐
The stretch seems to be slowing down โ space is getting tight, but still manageable ๐
pH & Soil Compatibility
One thing Iโm noticing more and more:
The drain pH stays low and doesnโt really increase, even with feed water at ~6.6.
After some digging, itโs likely due to the combo of BioBizz Light Mix and Advanced Nutrients.
BioBizz relies on microbes for pH buffering, unlike soils like Plagron Growmix or Canna Terra, which use dolomite lime.
Iโm also using Bud Candy, which seems to push the pH even lower by feeding the microbes.
๐ก Conclusion: If youโre using Advanced Nutrients, soils with lime buffering might be a better match.
๐ฟ Plant Status โ White Widow
๐ Height: 97 cm โ still stretching strongly
๐ง Drain pH: 5.7, but she doesnโt seem bothered by it
โ๏ธ Feeding at 85% of the Advanced Nutrients Masterline
โ Sheโs doing great โ no issues at all, healthy and vigorous!

AlpenZilla Week 8 โ Day 59 (Flower Day 29)
๐ Recap
Still using diluted osmotic water, but the drain pH remains stubbornly low โ stuck between 5.6 and 5.8 ๐
After trying with Canna pH+, Iโve decided to switch back to BioBizz pH+, which worked reliably in my last grow to raise pH when using Advanced Nutrients.
Apparently, the combination of Canna pH+ and AN doesnโt play well together ๐ค
๐ฟ Plant Status โ White Widow
๐ Height: 110 cm โ sheโs still growing steadily
๐ก I had to dim the LED slightly โ currently around 950โ1000 PPFD
โ Sheโs handling the light intensity very well, no signs of stress
โ๏ธ Feeding at 100% Advanced Nutrients Masterline
๐ Summary
White Widow looks great overall.
Even with the suboptimal drain pH, no visible issues so far.
Still, Iโll try to bring the pH up slightly again โ BioBizz pH+ is on the way.

One of those weeks where everything just works ๐
BioBizz pH+ is finally doing its job:

Other than that, itโs all about the usual routine: watering, observing, and enjoying the view ๐

๐ General Notes
White Widow is now at day 43 of flower โ slowly approaching the finish line ๐
๐ง Water uptake has noticeably decreased, so Iโve reduced the nutrient dosage by around 20%
โDo you guys do the same near the end of flower?
I remember reading it's common practice to taper off, but Iโd love to hear your thoughts!
โ๏ธ White Widow Status
Still going strong ๐ช
Buds are frosty, dense, and nicely uniform
๐ฌ Honestly, the pictures speak for themselves โ everythingโs running smoothly!

๐ General Update
Unfortunately, I ran into a nutrient lockout earlier this week โ some of you may have seen it in the comments.
๐ The drain pH just wonโt go up anymore, even after multiple flushes with light nutrient solution.
Iโm now down to 50% of the feeding schedule and reduced light intensity to around 600 PPFD to keep stress levels low.
โ๏ธ White Widow โ Day 51 of Flower
Sheโs clearly showing signs of the lockout now โ ๏ธ
Still, the buds continue to swell visibly, which is honestly a nice surprise!
It seems like sheโll make it to harvest without major damage.
Flushing only from now on โ harvest is planned for next week.
โ ๏ธ Drain pH is stuck at 5.6 โ completely off, but canโt be fixed anymore at this point.

๐ Final update before harvest
Tomorrow is the day โ White Widow will be chopped โ๏ธ
No more nutrients this week, just plain water ๐ง
Despite the pH lockout near the end, the buds continued to pack on weight โ some are up to 12 ร 5 cm in size! ๐ช๐
Super dense and frosty.
๐ค Iโm still a bit worried about how the aroma and flavor will turn out.
The lockout might have affected overall quality โ but only the drying process and the first test smoke will tell... ๐ฅ๐
White Widow is a reliable classic โ and this run confirmed why sheโs been around for decades.
The buds turned out compact, frosty and visually appealing ๏ธ
Even though the final yield of 76.35 g was a bit below expectations, she pushed through a late-stage pH lockout and still developed solid flowers
In terms of effect, she delivers a well-balanced hybrid high: uplifting in small doses, relaxing in higher amounts โ great for evenings or unwinding after work.
The terpene profile was pleasant, though not overly intense โ more on the earthy-spicy side.
Would I grow her again?
Yes, with better pH control and maybe in a slightly stronger soil mix.
Sheโs not the loudest strain, but definitely a steady and rewarding one if treated right.

AlpenZilla โ๏ธ Harvest Report โ White Widow
โ Final dry weight: 76.35 g
The buds are compact, frosty, and visually quite appealing โ๏ธ
However, with a total of 76.35 g dry, she unfortunately stayed below expectations.
โ That puts her among the weaker yields in this run.
๐ The late-stage pH lockout likely affected both appearance and final weight.
Still, considering the stress she went through, she made it to the finish line respectably.
๐ฟ Trim & Rosin Plans
Collected around 35โ40 g of trim and popcorn buds.
Iโll press 5 g of that into rosin and see what kind of return I can get ๐
