looks like nitrogen def. you doing 8mlpg micro and 16mlpg bloom? cal/mag at 5ml per gallon?

Yep. I would use a bit more Cal-Mag then that. It seems like it takes a lot to fix a problem but just that much to not have a problem. I use it every watering.

Red stems and red leaf margins are indicative of cooler day or night times, keep an eye on your night time temps, keep a temperature gauge in their, be cautious of receiving cross calculi advice! kilograms to nautical miles, millimeters to furlongs and the infamous milliliter to gallons, us or uk, yellow leaves with green veins is most definitely (Mg) def, shoot it out with the calmag or Epsom Salts!

i'd go to 8ml micro and 16ml bloom, gh is pretty friendly and at this stage your plants can and will use more food.
i use cal/mag at 5mlpg, but that's hydro, so perhaps go 8mlpg cal/mag as well like da mann said.

gh 3 part is directed ml per gallon on the label. easier than saying 1.6 teaspoons per gallon micro and 3.2 teaspoons per gallon bloom...

Yah and ur in a delicate moment right now, 3 weeks into 12/12, gradual change into needing more P and K is incoming over the next weeks. Don't worry about the purple stems, usually it's strain-dependent otherwise there is a deficiency but its so minor u don't need to worry really. My NL I just harvested had all branches purple and the main stem was kind of awesome-looking purple and green striped, it's no cause for alarm.
I reckon at this point you should be trying to slow the yellowing of the fan leaves and help bud growth with some kind of blooming fert and then observe. Good luck!
