i pour 50ml and agitate with durst comot (levelled). i got the stain even if i pour a bit more of 50ml
Also, the white specks and lines could be lint on the paper when exposing
Do you pre wash?
I have a few drums so always wash them well and leave them to dry on open air. I am preatty sure the problem is not there.Sometimes a few drops of chem don't get fully rinsed out between steps, clinging to the rear cap of the drum, or perhaps inside the rim. For that reason, I introduce an optional brief but generous water rinse step between the Stop and Blix phases.
The other potential problem, already mentioned, would be insufficient solution volume.
I wouldn't mess with trays unless you have very good ventilation across the sink, drawing the fumes away from you. One can become sensitized to RA4 chem.
But 30 seconds stop bath and 15 seconds rinse with water should be enough to prevent developer enter the bleach?
That's pretty minimal. Try 100-150ml and see how it goes.
I have searched the internet and nowhere can I find the amount of print developer for an 8x10 Durst 205 Codrum I found a drum on e-bay and while the outside of the drum specifies amounts for negatives and both Cibachrome and Kodak reversalI coudn't work out the amount needed for an 8x10 print
As it is meant for 8x10 negatives one might assume that the amount for negatives apply and it does say 50ml. So on that basis the OP's use of 50ml might be right but it might be as well if the OP were to try and discover the amount, if he can

If lack of developer in terms of quantity is the cause of your problem you'd expect it to be there in every print and as far as I can see it is confined to the sky area only - at least in the prints you have shown us
Yes what I saw is exactly what you have shown in #16. If this is a drum that is designed for 8x10 be that film or prints then my logic says that a 8 x10 negative is the closest to an 8x10 print and an 8x10 negative is the same size as an 8x10 print and b&w prints can even use developer that is more commonly used for negatives
If the print needs substantially more than 50 ml you'd think that Durst would give it a separate column which it doesn't.

We're looking at one little snippet from one print. Moreover, sky areas tend to be of uniform tone and slight variations show up more clearly in those areas even if they're present across the entire sheet. If you print an entire frame of rock formations like the little bits we see on the snippet as well, a problem like this will go entirely unnoticed.
I developed at 32C for 60 seconds.
Did not go up to 100 seconds. I think at 100 seconds i would get too short exposure times.

I noticed that with short exposure times (3-4 seconds) i have problem to reproduce same density as test strip.
