Red Stems, curling leaves, and yellow spots

Well, two nights ago I was looking at my baby and her stems were fine, but this morning when I checked on her, about a third or more of the the fan leaves' stems were red.
Why are they red now? Is it bad? Will they continue to turn red? What do I need to do?

For as long as I can remember my baby has had a few of the middle blades on the fan leaves curl. The last inch or so of the blade corkscrews. Not every fan leaf has a blade like this, but a few of them do.
Why is the middle blade corkscrewing?

Some of the leaves are also developing tiny yellow spots. Only a few leaves have them and usually only one or two little dots.
What's with the dots?

Right now my baby is like two months old and I feed her nutes once a week. I have been giving her this organic stuff, but it is only 1-1-1. Im giving her 1ml per liter. Should I give her more or less?

Any help would be appreciated.

red stems could be from cold or nitrogen deficiency, make sure temp is warm enough. check your NPK levels.. and upload a pic!

...do you monitor your pH?

sounds like mag to me, check your fert make sure its adequate.
