Mini fragrant noid phal leaves got dented spots
 

Hi, one of my mini noid phal that I bought from trader joes has developed weird spots on leaves on the underside and I'm worried as it seems to be spreading. I repotted her from moss to bark after I bought her home 3 months ago and she seemed to do well , lots of new roots but noticed these spots on the underside but waited to see if its spreading and it does seem to spread. Temperatures inside our home are around 72F daytime and 67F nighttime. I water her once every week and fertilize once every 2 weeks. Any idea on what this could be and how to treat the disease?

im no expert, but have you also noticed and wispy, single stranded spider webs floating in your plants? if so, i would say with confidence that is a false spider mite attack. we dealt with them this late summer and fall, and have had them at times in the past, and the healed bite marks lookmlike this and are found in the same places, along leaf edges and at the tips. but again, not saying this is absolutely what it is, and probly the more experienced will off their observations. best of luck!

Looks like old damage that I wouldn't be too worried about. Could have been munched on by an aphid or it could have gotten too cold.

Just keep an eye on it to make sure it doesn't get worse. Take another pic in a month and compare to this one.

thanks for your response. I havent noticed any spider webs . I've sprayer horticultural oil hopefully that will take care of spider mites if there are any. After a week will also treat it with miticide. Hope this will help :(

hmm I know weather has gotten cold but not sure if its due to cold. Will keep an eye on it and as you suggested will click pictures and compare after a month.
