This is a bad time of the year for succulents because they are African plants mostly, coming from below the Equator, they are winter grower here, and we must respect them, not knowing what you have I am not able to open that long link. the lower leave drop off, that is normal with most succulents, not to worry, in the winter new grow will come on the tips and that is where the flowers grow. Do you know the names of your succulets? If so I can help you I don't need to see them. Nothing is wrong, just keep down the amount of water you give them this time of the year until Oct. 1 then I would like you to change out the soil then to jump start them. Put a pinch of Bone Meal into each pot. Keep me posted if you have any more questions. I raise only succulents from Africa and a few from Mexico. Lots of bulbs, juat a few cactus. I know how to raise cactus because of my 20 years of training but can't ID them. Norma

May have already been suggested by others I share the common suggestion that each pot house one different plant per pot ( exceptions are the same lithops can share a single pot With out to much talking about pots Each pot will need some form of drainage and be of a relative size for developing the growth you want , size shape and materials of pots can be something for you to explore . Your soil links are basically okay to use for but as you read more into soils for & as your time and investment into succulents becomes bigger you may want to consider better options for soil materials. A bit higher end but may be worth the investment for you especially if you get the any type of plant in a pot cultivating bug ( succulents included) http://www.amazon.com/4pc-Soil-Sieve-diameter-Interchangeable/dp/B0007P4JAU/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1452090931&sr=1-1&keywords=soil+sifting+screen Yes there are sifters that can fit the bidding at wally world yet for some of us here compromising is something to be considered. Compromising; You may want to shop in a hydroponics store for super chunk sized perlite to replace http://www.amazon.com/gp/product/B00GTDI6YO?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 Chances are you may even find some type of pumice at a hydo shop, a bit pricey but if so grab a bag of it It's being suggested that you spend time in developing a made by you ( custom made ) soil for succulents. There are several forms of succulent soils though out the C&S forum yet fast sharp drainage seems to be the key As suggested start with a basic mix formed from some of the items you already have on hand by sifting and rinsing some of the items you already have on hand as to how and what do you do isn't mentioned I wouldn't ( and wont) suggest the sand be used with out a sifting and rinsing and a pic view of it after sifting for opinions ( I've never used it or have seen it sifted ) which can be easily replaced with sifted construction sand found at home depot or lowes http://www.amazon.com/gp/product/B00GTDI6YO?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 Sift all the three items as follows for a better mix: Apx 35 % sand from the link or after pic of yours on hand Apx 30 % of the bagged soil on hand and the remaining % be perlite Using the apx mix % is for each per pot not the over all % amount of each bag. The pot preference for most here is terracotta pots as they provide a breathable surfaces but plastic can also be used. What I do is make enough mix for several pots at a time then fill each pot then re-sift/ remix the soil back into the pot while potting in a plant. Some re-potted in the newer soil mix and draining pots will need a dryer soil> ( Example the lithops ) It might be suggested to let them pots dry for a day or two before re-potting and some will be okay to pot in a damper soil ( example your P afra.) PS. Use some ethics please chances are you wont overwhelm yourself and not overwhelm your plant(s). If you have questions feel free to ask on this ( your) thread. Feel free to read them but please don't ask your questions on another persons plant with problems threads As you get use to your new plant growing hobby ( thats an art for others) you found you may find a need to ask about a particular plant on a different topic feel free to start a new topic ( thread). Example; It would be considered ( maybe) rude of me to post a comment asking for advice on your thread. A small example of me being rude; What should I do so the vine will reach the side stick on this un-ordinary onion? Bowiea volubilis ; you need to concider is that rude can often end up in a very winding vine in a very messy wig

It kind of looks like an Echeveria pulidonis.

If overwatered, take it out of pot. Get all soil off the rots. Cut off any damaged - rotted, dry or broken (clen cut those). Let air dry for few hours. Get a pot with dainage hole. Prepare well draning mix. If nothing else, get perlite and mix it with soil 1:1. Perlite should be sifted or rinsed to get rid of dust. Pot plant in it. I would also trim (clean cut) those dry ends - not crucial, but looks better and plant will grow 2 or more 'arms'. Water only when almost completely dry: insert bamboo or wooden chopstick deep into pot, leave for few min. If dry when pulled out, time to water. If wet-damp, there is still lots of moisture and wait. They can grow many feet long in right conditions. Example photo from net (could grow even much longer than that): Slowly introduce to good amount of sunlight.
