I see in your diary your RH is 33. But in the pic it's 45, if it's cause you just watered it or something but the 45RH will be better for pre flower and lower it to your 33-35 in later stage of flowering.
Once you have decent air flow/exchange you'll be fine with a higher RH it'll grow faster in pre flower. You can even have it at 50. Up to you.
She looks week overall. Very healthy. Not to green, which many 1st time growers tend to think if you give extra grow it'll grow more, (not the case) i know I did. So for a 1st time you are doing very well. You will learn a lot from this grow and hey, next time give photos a try.
You could open her up a little, I know you shouldn't really defol during pre flower but take those big fan leafs that are blocking out your light to lower bud sites. Any larfy sites you get (there'll be many with autos) don't try bring the whole thing to harvest remove them, the lower bits of hairy larf. It's energy wasting.
Good luck with the rest of pre flowering and moving into flowering.
Bloom nutrients and if you have some silica for pests and it'll help make for a stronger plant
But don't worry if you don't have it.
