Is it just on old growth?Im
Not took sure. It looks like it ....your right!
Usually when they curl up like that I might have a temp issue or some Transpiration issues. Humidity etc. But I'm sure it' not either because I have een growing in My sealed room.for 2 years and know how it works......so I can' count those out.

If anything, it looks like a deficiency to me. Now, why? That's up to you to decide.
Somebody correct me if I'm wrong, but excess nutes result in leaf tip and margin burn, but that's not what you're seeing, OP. Instead, you're seeing an older leaf slowly show signs of deficiency, which is common in flowering because the plant will move mobile nutrients as needed, and especially from older leaves no longer photosynthesizing at an acceptable level.
