I am using my own built green house to prepare some chili plants for next years gardening season. I have planted various seeds and almost all of them have grown into seedlings. I have noticed that one specific sort of chili plant (peter chili) grows very strange:
- The first pair of leaves was very dark green
- After a day or two the first pair of leaves started to turn lighter and lighter green, to the extent one can see the "veins" of the leaves
- The subsequent pairs of leaves are all almost yellow
- It is still growing nicely, however the leaves are colored weirdly
- Yellowing is worse on newer leaves
- Other seedlings in the same area do not suffer from the same discoloring
- All 4 plants of the same sort look exactly the same
Plants are living a 14/10 hour schedule for light/night and have a constant 28°C. I am using a specific coconut based growth medium that came with the seeds and have also already fertilized it once with tomato/paprika fertilizer (I was thinking Nitrogen deficiency).
Below is a picture of one of the plants. It is hard to tell from the lighting with the phone camera, but the one on the right is much more yellow than the one on the left. Is this normal or what is causing this?
