im sorry i am unable to load a photo at the moment but I recently picked up quite a few new plants. within two days they have all showed the same signs and im in question as to what is really is. Black spotting that can also be bright orange its solid and puffy with me being able to scrap it away with my fingernail. i see no signs of pests or white really anywhere. upon observation i realized quite a few of the nurseries plants had powdery mildew i have since used PHed water and have kept constant air flow. besides pests what other problems could it be? i dont want to just start repotting everything for as most of them are not root bound and i feel would be in too large a pot for the size they are currently. my philodendrons are all fine and my zygo cactus seems to be taking the force of it pretty hard. in fact the succulents in general. i have a cert in horticulture and im a cultivator for a living so im sure i know whatt im doing when it comes to watering each plant to its needs. just so many answers and to my recent searches thru my books and google i have found somthing to the effect of if i were to type in a medical issue on the internet......they all say i have cancer. again i apologize for the vague description ill answer any questions and i can probably take a photo later but its killing me and i dont want to lose a plant. even a rocket scientist doesnt know when his rocket wont fly somtimes. thank you in advance

Adam, I'm sorry you can't load your photos. I thought new members were only limited on posting links. I'm not sure what your problem is. Maybe you can send photos to another member and they can post them? I'd be happy to post for you.

Scale insects come in all shades from green to orange to brown and black.

I hope you will be able to upload a photo or two soon, showing the problem areas. You may have two separate issues going on. You said you were able to scrape some away with your fingernail but some of the black solid round spots do not scrape off?

Leaf spots could be many things, scale insects, excrement from insects, virus or fungal issues.

Curious as to why you think repotting might be a solution for any of the possible problems?

Because if its some sort of edema due to the watering practices and neglect of the place i purchased them from then i want to get them into some dry soil specially because its the succulents having most of the blight. trust me i know re potting is NOT a cure all and is extremely stressful on a majority of plants. it was a sale because they are trying to clear out the winter growth in the green houses. i havent got around to it but a majority are bound and need it excluding ones that thrive in a tight medium
