Why are my lemon seedlings growing paler green leaves?

3 years ago

Hello, I have been growing some lemon trees from seeds over the last month. They started in small pots on a propagation mat, with 3 seeds per pot. 2 weeks ago I separated them into individual pots, planting them in cactus soil. They have ample drainage, are on humidity trays, and I spritz them with water at least once a day. I've been watering them when the soil is just borderline dry, which is every 3 days right now. They're in a west facing window (I'm in a townhouse so I only have east and west) in direct sunlight. I'm in Canada, so the sun is not very hot. I am planning on moving them off the sill when it gets cooler.


I've noticed that the most recent leaves to grow are a lighter green than the previous growth. Does anyone know what this would be from? They still look quite healthy, so I was thinking maybe a nitrogen deficiency? I'd read that I shouldn't fertilize for the first month if the soil I used had feed in it, which it did. But maybe it didn't have enough?


Any help is greatly appreciated!
