Two (apparent) bowel impaction deaths in juvenile H.macs

Good morning/Good evening.
I have had two deaths seemingly related to bowel impaction in juvenile H. maculatas. I'm looking for some answers as to why.
Let me first say that all my arboreal juveniles are kept in AMAC 7.75" x 4" x 4" enclosures with cross ventilation (one row of 1/8th" holes drilled near the substrate and two rows of 1/8th" holes drilled near the top of the lid, on opposing sides to mark the "front" and "back" of the enclosure)
Every arboreal I own is provided a cork bark flat, moss, and my substrate blend (40% coco fibre, 30% reptisoil and 30% clay, soil, sand loam for stability with a bit of ground up moss for moisture retention)
For diet, my juveniles are provided 3-4 crickets (1/2"-3/4") per week, and the occasional superworm, or first-second instar hornworm (approximately 1'-1.5" in length)
They are provided a water dish by means of whatever object I can fit into their enclosure (usually a plastic bottle cap)
The temperatures are approximately 79f-82f (they are kept approximately 2 feet above my bearded dragon heat lamps and I measure temps with an heat gun)

I'm trying to rule out errors in husbandry, although it is possible that an error on my part could have resulted in the deaths. I also keep pokey species, P. gigas, and P. cambridgi without incident, the only other deaths I've experienced with arboreals was during the sling stage where several P. cambridgi veils developed mold carried by leaf litter. I have not experienced this problem except with the H. macs.

An autopsy was performed, and while inconclusive, due to decomposition, it appears a solid white-yellow mass approximately 6-8mm around was located in the abdomen near the excretion area.

Are H. macs more prone to fecal impactions, or is there another explanation?

Sorry to hear of your losses.
Id say the sand or sandy loam type soils with clay can be like glue/concrete when the conditions are right. Alot of people ive talked to in the past had that type of soil with similar problems. Im also a excavator by trade and I've seen first had how hard these materials can get if too much moisture and drying occurs. Just excessive moisture on the anus of the spider from defecating mixed with said materials would turn to concrete. Just my two cents.

If you're using bentonite clay powder that may be the culprit. sounds like the feces became calcified

I left school & started my bricklaying apprenticeship back in 1976 & I know it was an exceptional summer, but I saw a JCB break the teeth of it's bucket in clay soil that summer.

hardpan sucks lol! here in socal the soil is ultra heavy clay, virtually 100% clay. makes it such a pain in the butt to dig things up and aerate soil, i have to soak it for at least like 6 hours just to make it workable
