So has anyone seen this before?
Gosh wish I could help but I am not experienced enough to identify nutrient problems. The dark green leaves and clawing look like too much nitrogen earlier? I am sure more experienced growers will chime in soon and I look forward to their responses so can get better at diagnosing my own plants!
In my nightmares
Too much nitrogen, and odd lighter color green leaves is leaf variegation. Not much you can do about that.
I would consider flushing to rinse out the medium. Then feed immediately with less nitrogen.
Ouch. Good luck!
Thanks everyone for some of your responses but in the end it’s one plant, I’ve never seen leaves do that so I asked. But she’s fixed and on to the next. Thanks.
