Что за ржавчина на моих листьях на 126 дне? Это дефицит cal-mag или проблема с корнями? Как вы думаете, как выглядит моя девочка? Созрела ли она?

https://growdiaries.s3-accelerate.amazonaws.com/static/post/photo/23964/1184736_autoflowering-xl-in-summer.jpg There are many affected leaves. They are Cream Mandrine XL Auto. They have been taken care of just like the Green Poison Auto but these are very good. Being bigger I guess it's a lack (N)?

Calcium deficiency or PH problem?
Is this a calcium deficiency ? given the soil mixtures (recipes in germ. week) unlikely. since they only get tap water, i checked the values Ca2+ 65.6 mg/l Mg2+ 17.3mg/l that's an 3.8:1 ratio. PH is 7.6, I never checked that tbh. doesn't the soil compensate for that?

Bound and wrinkly leaves
Some bottom leaves are wrinkly and where bound to eachother. These are new growths that grow from first 4 leaves. I'm having hard time googling the issue. What could cause this and should I be concerned? Last picture is before I split them.
