MrGrowDiarie The photoperiod journey begins! This is my very first photoperiodic plant from , and I’m really looking forward to seeing how she develops compared to the autos I've grown before. It's a different kind of process — more control, more patience, and a lot more potential. She's just getting started, still small, but already showing promise. Can’t wait to guide her through the full cycle and really see what she’s capable of under a proper light schedule

MrGrowDiarie Week 2 – Normal growth, just still small
She’s coming along nicely. Growth looks healthy and steady – nothing explosive yet, but that’s expected this early. Starting to push out her second set of true leaves. Color is good, leaves are perky. Everything looks on track so far, just early-stage growth. Let’s see how she takes off in the coming days

First topping & mainlining begins
Big milestone today – took the top off above the 3rd node to start her mainline. She handled the cut well, no droop, just a little sulk right after. Cleared the lower growth to leave those two strong mains, and tied them out gently to start shaping the structure. She’s still deep green and healthy, with thick stems that should handle the training without trouble. This is where the fun begins – looking forward to watching her bounce back and start building that symmetrical frame

MrGrowDiarie Day 36
The plant is now 36 days old and showing strong growth. After the earlier LST, she has responded well — the canopy is more even, and multiple tops are now exposed to the light. The leaves look healthy, with a nice dark green color, though a few of the lower leaves are slightly lighter, which is normal as energy shifts to the new growth.
The structure is getting wider and bushier, filling out the pot nicely. Side branches are catching up, which should result in a more balanced plant with many bud sites later on.

This plant is looking well-trained and spreading out beautifully! The main stem has been opened up with some strong LST, allowing light to hit every single top. New growth is healthy and vibrant green, with multiple bud sites forming along the branches.
The structure is flat and even, creating an ideal base for a wide, productive canopy. No signs of stress from the training – she handled it like a champ. Over the next few days, she’ll keep focusing on filling in those gaps and building strength before the flip to flower in 6

MrGrowDiarie Day 49
This smaller plant is at day 49 and has clearly been topped earlier in its growth cycle. The topping has encouraged a bushier structure, with multiple main branches now developing evenly. Instead of a single dominant top, the plant is pushing out symmetrical side shoots, creating a wider canopy and setting the stage for multiple bud sites.
The new growth is lighter green, showing healthy development, while the older fan leaves are darker and strong. The plant looks compact and well-structured, with tight internodes and balanced growth. The topping has slowed vertical stretch compared to an untopped plant, but the overall result is a sturdier, more manageable shape.
There are no clear signs of stress or deficiency — leaves are healthy, edges are smooth, and the color is consistent. The canopy is lower and denser than the bigger plants, but that’s expected after topping. With some time, the side branches will continue to catch up, forming a nice even top layer.
This plant is on track for a strong transition into flowering, with the topping already setting it up for a more even distribution of colas and better light penetration.

MrGrowDiarie Day 49
Since the last update, the plant has only shown very slow signs of recovery. There’s a bit of fresh growth appearing in the center, but overall it remains weak and far behind expectations.
The leaves are still drooping, though not quite as badly as a week ago. The pale green color persists, with some areas still edging toward yellow. This shows the roots are still struggling and nutrient uptake is limited.
The heavy topping has given the plant a wide, flat structure with many bud sites, but at the moment it can’t take advantage of that shape. The potential is there, but growth is stalled by the stress it’s under.
Watering has been kept very cautious — smaller amounts with longer breaks to avoid waterlogging. The medium was allowed to dry out thoroughly before watering again this time. Even so, the plant seems to be putting most of its energy into recovery rather than active growth.
Compared to the other plants, this one looks “stuck.” Because of that, my expectations have shifted — I now see it more as a learning project. The new strains I started alongside are doing much better and give me confidence for this run overall.
For now, the focus is still the same: no extra stress, no experiments — just steady care, patience, and time

This plant has been trained into a wide, flat shape, with multiple tops spread out evenly across the pot. The structure is low and bushy, clearly influenced by topping or LST, which has opened up the canopy for better light penetration.
Leaf color is generally healthy, a strong green with decent vibrancy, though some variation is visible. The lower leaves show stress — one is yellowed and deteriorating, likely from nutrient deficiency (older growth being consumed) or simply natural fading.
The canopy looks vigorous and responsive to training, but growth is still somewhat restrained; the plant doesn’t yet have explosive vertical energy. The root zone may still be recovering from earlier stress, but the overall appearance suggests it’s adapting well.
Going forward, the key will be to maintain even watering and steady nutrition, supporting strong root activity. Some light defoliation could help airflow under the canopy and direct energy into the developing tops. If conditions stay stable, this plant should be able to bounce back and continue filling the space effectively.

MrGrowDiarie Day 70 – Flower Week 1 (Flip on Day 67)
The plant has transitioned into flowering smoothly. The wide, low structure from the veg phase is still obvious—a dense, even canopy stretched neatly across the scrog net. Multiple tops are sitting at a uniform height, and the first small pistils are starting to show.
Foliage remains mostly healthy: a rich mid-green with a slight sheen. A few of the older fan leaves down low are beginning to yellow lightly, which is normal at this stage as long as it doesn’t accelerate. New growth at the top looks vigorous, a sign that the root zone is active and stable.
The post-flip stretch has started but remains moderate, which suits the flattened training style well. Light penetration across the canopy is excellent, giving every bud site an even start.

The plant looks strong and healthy overall. The canopy is filling out nicely, and the leaves have a rich green color with no major signs of deficiency or stress. The training net is doing its job well, helping spread the branches evenly and create a flat canopy. This will help improve light penetration once flowering begins.

The plants are deep into flowering now and really starting to fill out nicely. The buds have become dense and covered in a thick layer of trichomes, giving off a strong, sweet aroma that’s getting more intense each day. The pistils are starting to turn from white to a light amber tone, a good sign that the plant is moving toward maturity.
Overall health looks great — leaves are a rich green, with only a few showing minor fade on the lower canopy, which is normal at this stage. I’ve been keeping a close eye on humidity and temperature to avoid any mold issues as the buds continue to fatten up.
Feeding schedule remains steady with a focus on bloom nutrients and a bit of molasses to enhance flavor and resin production. Watering every 2–3 days, making sure not to overdo it.

The close-up view shows very healthy flowering development. Buds are stacking up nicely with dense clusters forming and plenty of white pistils still visible, showing that the plant is still actively flowering. The trichome production is already significant, giving the buds a frosty appearance. The sugar leaves around the buds are coated with resin, a good indicator of potency.

The leaves are still a healthy green, with only minor fading visible on the lower foliage, which is expected at this stage as the plant begins to draw stored nutrients from older leaves. The sugar leaves surrounding the buds show a perfect balance of color, and the pistils are gradually turning amber and curling inward, signaling that the harvest window is approaching.
The plant's overall posture is strong, with branches supporting the weight of the buds nicely - a good indicator of strong stems and well-managed airflow. The grow space looks clean and stable, maintaining ideal environmental control for these crucial final days.

On day 120, the plant appears to be in a very advanced stage of flowering, with large, dense clusters of buds forming across the entire canopy. The flowers are heavily coated with a thick layer of crystal-like trichomes, giving them a frosty and mature appearance. The leaves near the top remain mostly green, though some show subtle fading, while the lower leaves display more pronounced yellowing, creating a clear contrast between the upper and lower sections of the plant. The overall structure is wide and full, with many branches carrying well-developed buds. The environment’s reflective surfaces emphasize the size and texture of the flowers. The plant looks robust and visually mature, showing the typical signs of nearing the very end of its life cycle.

The plante shows well-developed buds covered in a healthy layer of trichomes. The flowers appear to be in their late flowering stage, with calyxes visibly swelling and the structure becoming more compact. The leaves show a mix of green and yellow tones-typical late-flower fade as the plant draws stored nutrients from the foliage. Some fan leaves are yellowing from the center outward, suggesting normal senescence rather than a deficiency issue at this stage. The buds themselves look stable, frosty, and maturing steadily.

The plant is now in its final stretch, and the maturity is clearly visible. Most of the foliage has taken on deep purple and dark reddish tones, giving the entire plant a strong late-season appearance. Many of the larger fan leaves are fading, curling, or drying at the tips, which is typical at this stage as the plant focuses all remaining energy on the buds.
The buds themselves look dense, swollen, and heavily coated in trichomes. The resin production is at its peak, giving the flowers a frosty, almost sugar-covered look. Most pistils have darkened and curled inward, with only a few lighter hairs still visible. The overall structure looks stable, with each cola standing firm despite the weight.
