Brazilian Rain Tree dropping leaves

[Jiipsea]

My BRT up until this point has thrived. I mean really thrived.

We moved 2 months ago. I set up the grow room exactly as it was before. Grow light, humidity tray, fertilizer, watering all the same.

Leaves started off yellowing in the center of the plant and falling off and it has now spread to the whole tree. They're not all turning yellow anymore some are just getting crunchy and falling off.

I sprayed with neem and no change.

There is new growth all over.

Thanks

Hmmmm... The thin leaves are very sensitive hort oils. What you describe is what happens when I forget to not spray mine. Usually, tropicals do better if they can spend summer outdoors. They rejuvenate with real sun and air and actually grow. They need to be adjusted to different light levels going out and coming in, but it's worth it if you can do it.

Do you have an air conditioner? Maybe it is more effective at pulling moisture out of the air.

I have plants that drop leaves if I move them to a different location in the yard. New growth is good.
