It's normal for the lower leaves to turn yellow during the flowering stage. This is a natural process known as nutrient remobilization, where the plant redirects nutrients from the lower leaves to support the development of flowers. As a result, the lower leaves may show signs of yellowing and eventually drop off. This is a common occurrence and not necessarily a cause for concern as long as it's limited to the lower leaves. However, if you notice excessive yellowing or discoloration on the upper leaves, it could indicate a nutrient deficiency or other issues that might need to be addressed. Keep up with your regular nutrient feeding schedule and ensure that your plants are receiving the necessary nutrients for a healthy flowering phase. Wishing you the best of luck with your cultivation!
