First time developing

[MaxFrank]

Hello, I just developed my first rolls of film ever, a 35mm roll of Ilford HP5+ in rodinal 1+50 yesterday and a roll of 120 delta 100 in the same rodinal dilution today.

I developed for 14 minutes today, first minute of constant agitation and then 2 gentle inversions every 2 minutes. I had some trouble loading the film onto the reels, I found the 35mm much easier to load, even dropped the film once by accident.

I did find some half moon marks on film, does this have to do with the fumbling whilst loading the film onto the reels?
Also does less agitation equal less grain in rodinal or is it the other way around. I know rodinal is not a fine grain developer, but for a 100 iso t-grain is this what I should expect.
Also the negatives came out quite purplish, is this normal or am I doing something wrong?

Less agitation equals less grain yes, and less contrast too. Rodinal is very sensitive to agitation.
I usually get purple negatives with TriX, never with HP5, could be not enough fixing maybe, you could refix the negatives you know.
Grain seems normal, maybe a bit too present for 100ISO but I wouldn't know too much, I rarely shoot below 400

Can't comment on the marks, could be that the film got bent or scratched, or maybe it was stuck in a way in the reels that the developer couldn't reach it.
