Black Spot on Venus Flytrap: Just an Old Leaf, Not Disease

Flytrap black spot

Possible fungus?

Flytrap under Burpee light (32W 6500K, 14 hrs). Black spot appeared. Bad?

Good news: nothing wrong. Just an older leaf senescing. Common during acclimation. Plants look great—Red Dragon is enviable.

Start feeding a bug or two (small fly). Boosts growth. You're doing well.
