Cream Mandarine XL Auto

[OneTwo12]

Hey Sweet Seeds growers,

Hope I started this topic in the correct sub-forum.
Currently I‘m growing one of the Cream Mandarine XL Auto and I‘m wondering if this seed got too much of the ruderalis genes. The plant is at veggie day 55 now and somewhat 30ish days in flower. It grew fast and I had to LST her by bending down the top. She started to build small flowers but after almost two weeks in flower the development stopped, and now -after 30 days in flower- it looks ridiculously. Even the amount of leaves is low. See the foloowing photos, so you can get an idea on how she looks like. 
Is this a known behavior for some seeds of this strain?

As I am growing other SS strains (Sweet Pure CBD Auto and Sweet Mandarine XL Auto) in the same box, in exact the same soil with exact the same fertilizers, I would say we cannot blame the conditions inside the box. 
All of the other Autos look normal - small but normal, with an all in all healthy shape. (I also added pics of those for comparison). 

If this is known to someone, is there a little hope that she will start growing more flowers and finishes well or is this a lost attempt?

Some growing facts:
9 and 11 liters pots (Cream Mandarine XL sits in a 9l pot)
BioBizz AllMix soil
Hesi flower and phosphor+ fertilizer 
250W Lumatek 

Let me know what you think.
