May I ask the OP where they have gotten their basic information culture information? I am curious where this information comes from. I see it many times from people new to orchids. I see nothing in the other post that states " Too much light". In fact I see the opposite many times over from experienced growers. I don't understand how the OP arrived at too much light conclusion. A Phalaenopsis is a tropical plant in a non-tropical environment. A Northern exposure and 50º temps would not benefit a Phalaenopsis or any other tropical flowering plant. Would you describe your present indoor conditons & culture? Would you tell us what steps you have taken to cure the "brown spot" problem? Would you be able to provide a photo? Would you tell us where/ when the plant was purchased? The OP has a declining plant. Spraying and misting cures nothing and can cause a variety of problems. You have a yet to be determined problem (I'd wager a lack of light). You have let it go for a few months. I would suspect your phal's problem has not improved. I strongly suspect you will face even greater problems quite soon. Spots don't disappear unless these were spots caused by a sudden shift in light (more) which happens in the fall months. You have brought it inside and the plant is now underlight, "darkening down". The spots would disappear under those circumstances. Plants leaves get darker the less light given. This is not a good thing. There is nothing that resembles Phalaenopsis culture (care). Buds don't stay forever. It's not a realistic expectation. I am not sure how that comes as a surprise to folks new to orchids . It's not the first time that I have seen an OP shocked that their bloom cycle is ending. I am not wondering if it is the price that is somehow associated bloom longevity. The OP posted more than 2 months ago. The plant may have run it's flowering cycle. Why will the spikes will be cut back to the 3rd node? Whay aren't they being cutt all the way down? I'm asking for my own curiousity, where this information comes from? Is the OP hoping the plant will re-bloom from the 3rd node? It is rare event for a phal in more ideal condtions to re-flower, a Big Box phal even more remote, a sick phal, probably suicide The plant needs attention and culture that fits a phal: - An acclimation to proper light. A south or East window supplimented by 14-16 hours of light every day Temps that are in the 75-80º range day and no lower than 60º night A solid watering regime which Richard describes above, not a dip in a bowl of water Dispense with misting if there is a problem. The risk of rot is quite high, especially when the plant is underlight. The plant is also risking over-watering. Misting does not increase humidity around the plant. Misting can cool leaves, leave spots, create rot. The plant needs time to grow a new set of leaves in proper phal conditons. Then it may reflower for you next year Clara

I suspect sun damage as well. The 3 leaves I can see in your photo that show damage are probably ok to leave on. The vast majority of those leaves are undamaged, and they haven't yellowed with age yet, so at this point it's just a cosmetic issue. If it bothers you, you can take them off. It looks like the row of leaves above is large enough that you might not even need to repot. Is there any chance there was some water on the leaves while the plants were in the light? That would explain the restricted areas of damage and why the edges are so even. Mark

Thanks for your input. I'm thinking too much sun, and not enough water. The spots just appeared a few days ago, and it has been really hot the past few days. I saw more of them appeared last night so I watered to see if anything happens.

The lesions confined by the veins look like angular leaf spot caused by the bacteria Pseudomonas syringae. It's pretty common on cucumbers. It survives on plant debris so sanitation is a big part of control. It also hangs out in the soil, so rotating out to something less susceptible for a few years would help. If re-planting with cucumbers, it's best to use pathogen free seeds if you can. I'm not really sure how that works in a home owner situation. There are also resistant varieties available. Unfortunately, there isn't any way to get rid of it now that you have it. You can slow the spread by watering early in the morning to allow the leaves to dry more quickly. Also, only pick fruit when the plants are dry.
