my gorilla is sick

Hello i have this Mody dick among my plants. It has been transplanted outdoors 3 weeks ago. It is in a 30 gal hole filled with biobizz allmix soil. Never fed her, she got only rain water. Temperatures are constant between 20-29° C, has been raining a bit every other day. Can somebody tell me what's up with her ? thanks

Nobody ever seen this ? c'mon i know there's somebody out there with experience that can give me a hint

What's the pH like? It looks like a blockout of immobile elements like iron from pH.

Or maybe she's actually lacking immobile elements since you said you haven't fed anything.

Could also be sulfur.
