m0useanswered grow question a year ago first off disable any ad-block or script editor if you have any running on your browser, they can negativity effect the function of the site and in the past, they have removed or blocked crucial buttons like edit week.
So the main thing you want to do it go into your diary and look right below the weekly layout and above where the picture load for your diary.
There is a small grey box that says [EDIT WEEK] and [REMOVE WEEK], if you hit remove week, it will kill that week. not ideal, so hit [EDIT WEEK].
Your now back into the week editing it like the firs time when you created the diary. You can upload/remove images if you wish, change the weekly comment, anything you want to change, then you scroll down the page and hit the green button titled SAVE.
When you hit SAVE it will have a pop up asking you to pick the diaries new cover photo based on the pics you just uploaded or that are already uploaded to the diary. This is where you can change this. If you don't want to change it hit cancel or just exit the browser with out clicking on any of the images.
One other edit option exists. it goes back to where you are inputting details like the seeds used and the type of substrate used, your tent and lghts exct.
That is done by hitting settings in the top right part of your diary, it will have multiple options, EDIT, Remove, Hide
Edit will take you to a page where you can edit details.
Remove will remove the diary as long as its not entered in any contests
Hide will make it look like the diary is deleted to everyone but you.
Good Luck!
