Higher rates of contam on subsequent flushes?

So I had 5 cakes fruiting in my SGFC. One of them got the trich before the fruits were very big so I tossed that one to avoid contamination of the other 4. The other 4 fruited beautifully and I have received several excellent flushes. After 2 flushes one of the cakes showed contam signs so I pulled it from the chamber and tossed it, the rest continued with that flush. I dunked and rolled again, and all 3 cakes started to produce nice pins, but one of them started showing green mold right before the mushrooms got to a decent size so I pulled that one and tossed it. The other 2 fruited as usual. I dunked and rolled those 2 and put them back in the chamber, and now one of them is showing signs of cobweb. Is it natural for cakes to get higher rates of contam on subsequent flushes as they approach the end of their lifecycle, or is the problem coming from my SGFC? I have another jar that colonized way slower than the rest and is ready for birth, I think I'm going to sanitize my SGFC with isopropyl alcohol and replace the perlite just in case, but I was just wondering if this was normal in the life cycle or if I'm going wrong somewhere?

Yea man, as the substrate reaches the end it will be more sussepitble to contamination

It is natural, for sure. Both Trichoderma and Dactylium are parasitic on your mycelium, which is weakening with each flush as it pours its stored nutrients into fruiting and producing spores, two very expensive processes. Eventually it will succumb to the infection, and you'll have to toss it out. 
Very observant.
