I do not know about the spots--I can hardly see them...
What I can tel you? The a Bromilliad blooms for a long time--and then stops...
The bloom will decline and wither--and the leaves may look so-so.
The Bromiliads we all buy bloom a long time--(2-3 months),and hen the bloom withers and gets sad looking.
This same Bromiliad will NOT bloom again. INEVER!!! t is done!
In time--it will grow "pups" from underneath the Momma plant. These will be the new plants.
The pups will grow bigger and bigger---and the Moma plant will decline more and more...
Eventually--you have 2 options. Dig up one of the Pups, making sure you get some roots with it,
repotting the Pup in a new pot in fresh soil and letting it grow until it is mature enough to bloom.
OR--cut the dying Moma plant away--and allow the pups to become the next "generation"...
How to make these new Pups bloom--is another story. If you do not know--d-mail me back.
I am curious too. I recently purchased one that had similar damage. The leaf tips are damaged and there is a spot on one leaf.
When yours have become white, I think it is scarred over from earlier damage.
I wondered how long you've had your bromeliad? I had suspected mine was due to overwatering in the store or damage caused by water on the leaves while in the sun. It is like an intensified sunburn from water pooling on the leaves and damaging them.
New to Bromeliads but have been reading many articles regarding growing and care. have the same problem on some of my plant leafs. Was not sure how to water plants at the start and left water standing on leaves. Article relates that the water remaining on leaf acts like a magnifying glass and burns the leaf.
However---one must always keep some water in the "cup" of the Bromiliad.
The "cup" is where all the leaves emerge--forming a 'vase" type of a swirl.
keep fresh water in this--always--
In the rain forests, Bbromiliads live in the tree canopies and never on the ground.
These type of plants are called "Epiphytes". They gather water in the "cup" from the rains and
feed on any rotten insects that fall in there.
Orchids are also Epiphytes, as are Epiphylums, Mistletoe and other tree-dwelling plants.
Not sure this helps--but understanding your plant's life cycle will help you.
