Nicotiana benthamiana is flowering prematurely, and its leaves are yellowing and wilting, it should be producing more leaves.
I recently started helping my sister with the planting. She mentioned that a year ago, using the exact same methods, the plants grew successfully; however, the plants now look like the ones in the photo (at 25 days old). We use tap water and NPK 12-12-12 fertilizer. My sister waters the soil surface every 2–3 days, while I water twice a week, yet the plants show the same condition. 16 h light
