Why is my Purple Kush still green?

They're in the 7th week since the 12/12 switch and they're not purple at all on the outside as far as I can tell. Does that mean I gave them too much nutrients? Or will it change in the flushing phase?

in 7th week is only about 4-5 weeks of actual flowering. ;)
Mine started to flower about 3 days after the switch, meaning that I saw the bud sites start to form at that point. With that said, is there a way to tell when to start flushing? Should I just start around the end of the 8th week after 12/12 with Final Finish and then water until the tricomes are milky white? Or should I wait a little longer than that? Like is it okay to flush longer than 2 weeks or will i stunt growth?

Don't flush, reduce ur feeding down to 400-600 ppm when u start seeing ur buds swell up and around. A third of your hairs are orange, then keep the reduced feed until harvest when all the hairs are orange/dark colored. At this point you can harvest based on trichomes

I have 2 purple strains. The first, a cheesecake, turns purple no matter what temp. You probably have one similar to my second, a blue mystic, it needs a drop in night temps to show any purple.

Hope that helps.

Edit: It usually comes out in the later weeks.

Flushing is a myth. If feeding chemical fertilizer, just cut back all fertilizer/food 50% for the last 2 weeks, but do not flush/starve it. The plant requires Magnesium, and Sulfur in the very last stages, and these 2 chemicals are quickly depleted by marijuana, especially in container grown plants, and using chemicals for fertilizer.. Marijuana is a huge consumer of Magnesium. These 2 chemicals are also not stored in the plant, nor are B Vitamins which are responsible for metabolism, and are also quickly depleted.
I use Epsom Salts for my source of Magnesium, and Sulfur/Magnesium Sulfate. Calcium Nitrate for my Nitrogen, and Calcium source, and dont use Cal-Mag.
Sulfur is one of the main chemicals for Terpene production.

Does this noticibly effect the taste or have you done a side by side compared to calmag?

My only purple grow was purple from early flower on. Just because they call it so doesnt mean you will see it.
Cold temps, not required for a genetic purp

Try dropping “lights on” temps to low 70’s and lights off just a few degrees lower. You can force it out with the cold.

here’s a pic of my own plant I did it to.

My feeding regime just requires Epsom Salts vs Cal-Mag as my Calcium, and Magnesium source.

As long as one is supplying the basic nutrients, in the correct ratios, it probably doesnt matter between Cal-Mag as your source of Ca/Mg, but doing this you would need to also have a Sulfur source.

The base formula for chemicals is
4-20-39

Then I add
15.5-0-0... Which is Calcium Nitrate, and is my source of Calcium, and Nitrogen.. So now, Ive eliminated the need for more Calcium, and Nitrogen as in Cal-Mag. Cal Mag also supplies 5-0-0 Nitrogen

After mixing the Base Formula, and Calcium Nitrate my NPK is 19.5-20-39

I then add

Epsom Salts. This supplies my Magnesium, and Sulfur.

I start out with a low PPM in Seedling Stage, and slowly increase until the last 2 weeks of flowering. I cut NOTHING BACK until then.

This is how I do an average 8 weeks flowering strain. PPM may vary by strain, but not alot.

At flip, Ill keep slowly increasing PPM of 19.5-20-39, and then in week 2.5 I will increase the P-K in the form of MonoPotassium Phosphate 0-52-34. I will use this until week 4, and then give the Epsom Salts a Boost from weeks 5-6, and then cut PPM by half from week 7-8.

Well as I am stumped give me a few days of reading to get back to this as it seems I have a bit to learn other then my basic 3 part nutes and adding calmag and armor si lol

Just remember Keep It Simple. Give a correct ratio base fertilizer, with micro trace minerals.

Thats it basically.. Dont over think it, and make it more complicated than it is.

All there is to growing weed is having #!>>> GOOD GENETICS..... a good soil/medium. All the food it needs in the correct ratios, good ventilation, and a strong light source.

After that learing the correct feed level, and frequency of watering are all one needs to master growing weed. It is after all a weed.

Thats it.

i would say its probably not real purple kush, some purple strains of marijuana turn purple from the leaves inward as the plants ripen. ex. grand daddy purp you can click the link to my grow journal in my signature those particular strains are very temperature dependent. true purple strains such as true purple kush the leaves will be green you may see purple stems there will be some variation. however the flowers will be purple right from the start i can also back this up with a photo here is an example of purple kush
