So I’m wondering why the stems are red what deficiency is going on here!?!
What are the red stems from?

Could be a phosphorous deficiency, either because there isn't enough present, it is not in a form that is readily accessible, temperature is too low (causes issues with uptaking the element).
There is also a genetic trait that causes "purpling" in cannabis, although I do not know if it is exactly that or it's a case of the thing causing the plant to have issues with accessing/using phosphorous.
There may be other causes (for example, I think a magnesium deficiency might cause purple stems but you'd probably be seeing other symptoms with that, and increased levels of anthocyanin probably would, but I don't think that's especially likely with cannabis plants), but those two are, as far as I know, the most common.
You can try adding a little Epsom salt to your water to see if it's a magnesium issue (Epsom salt is magnesium sulfate, and available in every drug store / pharmacy and almost every grocery store that I've ever looked in for the stuff). I suppose you could also use a "Ca/Mg" product, but the ratio of those two elements is also important, and if the plants are lacking in Mg but have plenty of Ca, then it might not help a great deal to add more of both of them.
Err... As usual, this post is "IMHO." Your mileage may vary

Thank you. This was after almost two weeks of flushing, day of harvest.
