Need help figuring out what this weird blob is attached to my plants

[RJ0910]

I have a 5 gal shrimp tank I'm using to breed wild shrimps planted with some amazon swords, vallisneria, guppy grass, hydrilla, water sprite and an unfinished monte carlo carpet stocked with wild shrimp, 1 male guppy, ramshorn snails and a few neocaridina shrimps. It has no filter, and no heater. 4 weeks-ish after the tank's establishment, i noticed this weird white blob on the guppy grass' leaf which I removed immediately and I didn't notice until a few weeks later when I found a similar blob on the still carpeting monte carlo that the blob was stuck to guppy grass at the back of the tank hidden by the amazon swords so I replaced the guppy grass with the blobs and hoped that the guppy get rids of the rest of them but no it has now spreaded everywhere and I don't know how to get rid of them so I need help. I think they're eggs of something but I'm not sure what, can't be ramshorn snail eggs because they look completely different and there's a lot of detritus worms hanging around the tank lately so it could be that.

Overfeeding .
The second and last picture is food for sure .
The detritus worms being more noticeable would be another indication of overfeeding ..

Yes I sometimes overfeed so it's understandable that the detritus worms are finally becoming more noticable but I always drop food into a feeding dish so the white stuff can't possibly be uneaten food and the ones on the 4th picture is under an amazon sword leaf and food can't just swim under a leaf and stick there. ?

Maybe the uneaten food is getting moved around by the water flow as it decomposes and settles in dead spots where you are seeing the mold?

There is no filter so there's not much water flow going on in the tank.
