Absolute beginner looking for advice for one plant

[BalticGrower]

Hi everyone. My name is Karl and I'm growing a few small plants in iGrow Cans from the Dutch company (though their products seem to come generally from Spain) Royal Queen Seeds. These starter kits contain coconut substrate and a fertiliser added right from the start - as a one-off for the entire grow.
As of today I have a problem with one of them: Quick One, an autoflowering plant. As of today, 15 days after Germination, the leaves of the top node have been turning yellow from the inside out. Is it perhaps getting too much direct sunlight (ca. four hours in the morning and about the same in the late afternoon, early evening). Or am I over or under watering it? I'd really appreciate any advice anyone could give me.
Many thanks in advance!

Hello, I am growing a couple of plants from Royal Queen seeds and they have done well. Definitely good genetics.

As far as the yellowing, possible a lack of nitrogen from over watering. Also check the ph if possible, 6.0-7.0 is the range you need.

I would say its not from too much sun, they love it. If the others are doing well with the same process its likely that specific variety having trouble with the watering.

Many thanks for the reply! I'll look into getting a test kit for testing pH.

Hello from France

could be overwatering or lack of nutrients.

Merci beaucoup! The fertiliser I mixed with the soil before planting is supposed to be enough for the entire grow, but perhaps I should add some nitrogen...

I use a probe similar to this one, it works well.

Overwatering -- Watering too frequently.

what kind of light is this plant getting?

Many thanks for your reply. It is getting natural sunlight at an opened window facing east in the morning and at one facing west in the late afternoon and evening.
