Dracaena brown tips? Fluoride in your tap water is the usual cause.
Corn plants, marginatas, Janet Craigs and lucky bamboo all share one weakness: fluoride. It's in most US tap water at a level people never notice and dracaenas can't tolerate. The brown tips are the plant keeping score.

Is it your water?
Tips and margins brown and the browning creeps slowly inward over weeks.
The plant is otherwise healthy — good color, new growth, firm cane.
You water from a city tap; your spider plant or peace lily has brown tips too.
Two of three and it's the water:
Why dracaenas are the canary
Dracaena fluoride sensitivity is so well established that growers use these plants to detect it. Fluoride accumulates at the leaf tip and margin where transpiration ends, kills the tissue, and leaves a dry brown edge with a yellow halo.
Three sources add up: fluoridated tap water, perlite in the potting mix (it can leach fluoride), and phosphate fertilizers. The water is the one you control every week.
Chlorine and chloramine add root stress on top, and softened water adds sodium. Letting water sit removes some chlorine and nothing else.

Three steps to try
Switch to filtered, remineralized water tonight — the filter removes fluoride, which sitting water never will.
This is the single change that stops new fluoride from arriving at the leaf tips.
Flush the pot once to move accumulated fluoride and salts out of the soil.
Water slowly until it drains freely; repeat with a second can to rinse the root zone.
Trim brown tips to the leaf's shape, then watch the leaves that open after you change the water.
Follow the natural leaf line and leave a tiny margin of brown so the cut doesn't spread.

What else it could be
Over-watering makes a dracaena's lower leaves yellow and the cane soft — different look, different fix. Direct sun bleaches and scorches whole leaves. Cold water on the roots can brown tips too; room temperature is right.
Brown tips by dracaena variety
Dracaena marginata (dragon tree) — thin leaves show tip burn early. Tips turning brown on a marginata that is otherwise growing well are almost always fluoride.
Dracaena Lemon Lime and Warneckii — the pale stripes brown first, as tips and as streaks along the margin.
Dracaena Janet Craig and corn plant (fragrans) — broad leaves brown at the tip and then yellow in a band behind it.
Lucky bamboo (Dracaena sanderiana) — grown in water, so it takes the full dose. Yellowing stalks and brown leaf tips are the sign; change to filtered water.
Ti plant (cordyline) — a close relative with the same fluoride sensitivity; brown tips and margins on an otherwise healthy ti plant are the water.
Yucca — also in the family; dry brown tips on stiff upright leaves are fluoride and salts.
