Cephalotus Leaf Tip Yellowing: Normal Aging, But Light Is Too Low

Cephalotus

Cephalotus setup

Cephalotus "Hummer's Giant" indoors under "Smart Plant Light" (6500K, 6" above), 71–74°F, RO/rain water, moist not wet, light mist of dilute orchid fertilizer monthly. Leaf tips yellowing; growth slowed.

Yellow Tips: Normal Aging

Tip yellowing on older non-pitcher leaves is natural.

Real Problem: Light Is Far Too Weak

The "Smart Plant Light" is not bright enough for Cephalotus. Only Mexican Pinguicula tolerate it. Your plant shows classic low-light signs: large, thin, all-green leaves; pitchers lack red coloration.

Fix

• Move to east/west/south windowsill with direct sun.
• Or upgrade to 23W+ 6500K CFL or 2-tube T5 at 6", 13-hour day.
• Expect some burn on old leaves—trim them.
• Increase feeding to every 2 weeks.
• Repot to 5–6" tall pot (long roots): NZ long-fiber sphagnum + perlite, or 50/50 peat/sand.

More light = compact, colorful, vigorous growth.
