From the photos, it does indeed look like your plant may be experiencing a calcium deficiency. The spots on the edges of the leaves and the way new leaves are growing in can be indicative of this issue.
It's also worth considering that fluctuations in pH levels can sometimes mimic nutrient deficiencies, including calcium deficiency. Ensuring a stable pH level within the optimal range for nutrient uptake is crucial for preventing deficiencies and promoting healthy plant growth.
To confirm the diagnosis, it may be helpful to closely examine the affected leaves for any additional symptoms, such as necrosis or leaf curling, which are common signs of calcium deficiency. Additionally, you can try adjusting the pH of your nutrient solution to see if it improves the condition of your plant.
If you suspect a calcium deficiency, supplementing with a calcium-magnesium (cal-mag) solution can help address the issue. Cal-mag supplements are readily available and can be added to your watering regimen according to the manufacturer's instructions.
Keep an eye on your plant's progress after addressing the potential deficiency and monitor for any improvements in leaf health. If symptoms persist or worsen, it may be necessary to seek further assistance or consider other potential factors contributing to the problem.
I hope this helps clarify the situation, and I wish you the best of luck in resolving the issue with your plant!
Happy growing! 🌿
