My crops are being popped out

Have you given them enough light? Crops will pop off if the light level is 7 or below.

Yes. The nearest light source, a torch, is about 4 blocks away.

There's not enough light in those spots. If you place more torches, they shouldn't pop off anymore.

But my crops never popped out with that very same light disposition. I could assume that pots are disturbing the light but I had this issue before placing those pots (supposedly for the bees to pollinate their flowers although they aren't making them sense, but that's another issue). I'm thinking to build light posts made with fences and lanterns to try to resolve that. But honestly I haven't experienced this before, I can bet that this was until 1.13 came.

Torch has light level 14. Count down from light source, you will get a 7 and possible 6 since the torch is above the ground. Add light in the middle where grass path is at OR work around by rearrange your crop with lights.

Yeah in the pics the spot that has no plant has a light level of 7 if you count from the torch. So this is working as intended.

A simple fix for the given layout would be to replace those torches with lanterns.
