How it usually goes wrong
- Leaves turn glassy from the stem outward
A leaf of the baby rubber plant that should be firm gives under light pressure and stays dented, and those beside it follow within days.
Succulence is a drought adaptation, and the same tissue that survives a dry month rots in a wet one. The moist but well-drained or well-drained its source names is the whole instruction.
Telling it apart: Whether the damage starts low. Rot works up from the soil line; thirst shows first in the oldest leaves, which wrinkle rather than soften.
RHSDiagnose a soft, mushy stem on this Baby rubber plant- The plant grows thin and sparse, and leans
The baby rubber plant looks sparse rather than sick: fewer leaves, spaced further apart, all angled toward the window.
Its source puts it in medium light. Under that, each new leaf costs more than it returns, so the plant builds fewer and thinner ones.
Telling it apart: Whether old growth is affected. Light shows in what arrives next; feeding shows in what is already there.
Clemson ExtensionDiagnose leggy growth on this Baby rubber plant- Yellowing that begins at the lowest leaves
Colour goes before shape on a baby rubber plant. The lowest leaves yellow evenly, stay soft to the touch, and the compost two inches down is still wet from the last watering.
Its source describes soil that is moist but well-drained or well-drained. Roots held below that are short of air, and roots short of air stop moving water, so the plant wilts in a wet pot.
Telling it apart: Whether new growth is affected too. Root damage shows up everywhere at once; ordinary leaf loss shows only in the oldest leaves.

What this does not cover
The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.
Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.
If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
