I would hit it with some calmag plus iron

Find you a good fertilizer to do it top feed and then give her about two weeks and she will be amazing

As mouse said She looks like she's struggling. Feed try something dif.. you said the others are good, that's just an example of phenos. They're all dif. That might need an enzyme ph adjustment. More compact soil. Whatever. She's dif. So you need to meet her needs bud She needs feed Basic NPK growth 5-3-2 or 1-1-1 1st will do you better that'll push you through pre till most of pre flower. Then bloom 5-15-10 5-25-30 all dif ones you get my drift. I like to have control over my npk. I use raws when I'm finding something lacking. Raw products are very cheap especially NPK But any good 3in1 that'll have a G,B,M
