Yellow leaves
Why are my Pinstripe calathea's leaves turning yellow?Calathea ornata
Yellowing is the most common distress signal a Pinstripe calathea sends, and it almost always traces back to watering. On this plant it tends to show up as yellowing leaves and mushy leaf bases — here's how to read which cause is yours.
Overwatering & root rot. Stop watering. Let the top 2 to 3 cm of soil feel dry to the touch completely, make sure the pot can actually drain, and only water again once it's dry. Because this plant's roots are delicate, unpot it at the first sign of a soft or sour-smelling crown rather than waiting.

What's causing it
Overwatering & root rot
How to tell: The soil is still wet days after watering, the lower and oldest leaves yellow first, and the crown may feel soft — this plant's dense, fine roots rot faster than a tougher foliage plant's, and yellowing leaves is usually the very first sign.
The fix: Stop watering. Let the top 2 to 3 cm of soil feel dry to the touch completely, make sure the pot can actually drain, and only water again once it's dry. Because this plant's roots are delicate, unpot it at the first sign of a soft or sour-smelling crown rather than waiting.
Tap-water minerals (a real trigger on this plant)
How to tell: Unlike most houseplants, Pinstripe calathea is genuinely sensitive to the salts and fluoride in ordinary tap water — a general, all-over yellowing with no soggy soil and no light problem often traces back to this rather than watering technique.
The fix: Switch to filtered, distilled, or rested rainwater, and flush the soil every few months to clear built-up minerals. Sensitive plants like this one often green back up within a few weeks of the switch.
Too little light
How to tell: The yellowing comes with dull, fading leaf patterning and pale new growth leaning toward the nearest window — Pinstripe calathea is medium / indirect light and its markings wash out well below 2,000 - 10,000 lux.
The fix: Move it to a brighter spot within its medium / indirect light range — the patterning sharpens back up within a few new leaves, but keep it out of harsh midday sun, which scorches.
Thirst (underwatering)
How to tell: The soil is bone dry, and the yellowing arrives alongside crispy brown edges rather than soft, mushy growth.
The fix: Water thoroughly — every 7 to 10 days in summer is the usual pace for a Pinstripe calathea — then settle into feeling the soil before every watering rather than watering on a fixed day.
Hungry (nutrient shortfall) — but easy to overcorrect
How to tell: Older leaves fade evenly and growth has slowed after many months unfed, but this genus is also easily salt-burned by fertiliser, so don't overcompensate.
The fix: Feed at a quarter to half the label strength through the growing season, flush the mix with plain water every couple of months, and refresh the top layer or repot if it's been over a year.
Simple old age
How to tell: One of the older, largest leaves slowly yellows from the outside in over a couple of weeks, while the new furled leaves emerging from the centre look completely healthy — normal retirement on a Pinstripe calathea, not a symptom.
The fix: Nothing is wrong — snip the spent leaf off at its base and carry on. Plants retire their oldest leaves.

Switch to filtered or rainwater since this plant is genuinely salt-sensitive, check the mix regularly rather than on a fixed schedule, and keep humidity up.
Common questions
Should I cut off the yellow leaves on my Pinstripe calathea?
Once a leaf has gone fully yellow it won't turn green again, so it's fine to snip it at the base — it lets the plant put energy into healthy growth. Don't strip lots at once, though; if many are yellowing, fix the cause first.
My Pinstripe calathea is yellowing evenly and the soil isn't wet — what's going on?
Check your water source before anything else. This plant is unusually sensitive to the minerals in tap water, and an even, all-over yellowing with no soggy soil and no light problem often clears up within weeks of switching to filtered or rainwater.
