For what its worth, I uploaded two of your pictures to chatGPT and got some responses.

The image shows a cannabis plant with some specific features on the leaves. From what can be observed:
1. **Leaf Color and Texture:** The overall green color of the leaves looks healthy, but without a clear view of the entire plant, it's hard to provide a complete assessment.
2. **Leaf Tips Curling:** There's a noticeable curling or "clawing" of some of the leaf tips. This can be a symptom of several issues:
- **Overwatering:** Cannabis plants that receive too much water can develop droopy, claw-like leaves. Ensure that the soil dries out somewhat between watering sessions. Overwatered soil can also deprive the roots of oxygen, causing further stress to the plant.
- **Nitrogen Toxicity:** Too much nitrogen in the soil can result in dark green leaves that appear shiny and display the clawing effect. If you've recently added a high-nitrogen fertilizer, this could be the cause.
- **Heat Stress:** If the plants are too close to lights or in an environment with high temperatures, they can exhibit curling or drooping leaves. Adjust the light height or improve ventilation to alleviate this.
3. **Yellowing of Lower Leaves:** Some of the leaves appear to be slightly yellow, particularly near the base. This can be due to:
- **Natural Aging:** It's normal for the oldest leaves (usually found at the bottom of the plant) to yellow and eventually drop off as the plant matures.
- **Nutrient Deficiency:** Yellowing of lower leaves can be an early sign of a nitrogen deficiency. However, if the upper or newer leaves are yellowing, it could indicate another type of nutrient deficiency, like potassium or magnesium.
4. **Leaf Spots or Blemishes:** I can't observe any clear spots, blemishes, or other significant anomalies on the leaves, which would be indicative of pests or diseases.
For a more comprehensive diagnosis, it would be beneficial to have a detailed history of the plant's care regimen, including watering frequency, type and frequency of nutrient application, lighting conditions, and temperature and humidity levels. Additionally, inspecting the underside of the leaves can help detect pests like spider mites or aphids, which can also cause various leaf symptoms.

From the image you provided, the cannabis plant seems to be in a healthy state, but I can offer some observations and suggestions regarding its setup:
1. **LED Light:** The LED light fixture above the plant does appear to be small relative to the size of the plant. Cannabis plants, especially during their vegetative stage, benefit from strong, consistent light exposure. Insufficient lighting can lead to "stretching," where the plant grows tall and spindly as it tries to reach for more light. This can lead to weaker stems and reduced yield. The plant in the picture does appear somewhat tall and stretched, which may be a result of the light not being strong enough or not covering enough surface area.
- **Suggestion:** Consider upgrading to a larger LED light or adding additional lights. The wattage required would depend on the specific needs of the plant, but generally speaking, more light (up to a point) is better for cannabis during its vegetative stage.
2. **Plant Structure:** The plant has long stems and seems to be stretching upwards, which could be a result of insufficient lighting, as mentioned. Providing more light can help encourage bushier growth.
3. **Setup Location:** It's notable that you have the plant in a bathroom setup. Bathrooms can have high humidity, which is beneficial during the vegetative stage. However, too much humidity during the flowering stage can increase the risk of mold and other fungal issues.
- **Suggestion:** Monitor the humidity levels and ensure there's adequate ventilation, especially as the plant transitions into its flowering stage.
4. **Support:** As the plant grows, its branches might become heavy with buds. Ensure the branches are supported to prevent them from breaking. The current PVC pipe structure seems to provide some support, but as the plant matures, additional staking or tying might be necessary.
5. **Training Techniques:** Techniques such as "low-stress training" (LST) can be employed to maximize light exposure to all parts of the plant. This involves gently bending and tying branches to create a more even canopy, which can increase yields by making better use of available light.
In conclusion, based on the image, upgrading or expanding the lighting setup might benefit the plant, especially given its size. Proper lighting is crucial for optimal growth and flowering in cannabis plants.
. Keep it in mind and the next growing start to practice some Low Stress Training several weeks before flowering starts.
