Well, other than calcium and related phosphorus, it might be slight potassium issue.

Phosphorus deficiency? PH problems?
I'm on day 56 of flowering, and only the Mimosa Evo's leaves are starting to turn red, pinkish purple. I suspect a phosphorus deficiency/absorption problem due to the pH being too low. Or is it genetic?

Purple Stems
On Day 11 i recognized purple stems but only at the 2 top leaves, i hope it is only genetics or maybe the cold night 2 days ago when it went down to 17 celsius.

Color of top leaves
Small question about the color of the top leaves, is it a lighting problem, or something else? The leaves on the lower floors do not (yet) have this color. I'm thinking it's genetics but I'm not sure. Thank you

Og Kush quick stress.
OG Kush week 5 decided to show seeds red stems etc she got hermies, just inspected close I'm wondering if I should just throw her,or keep her as other girls got no problem at all, it got hit by being overdried when I was in hospital a few days I'm guessing there's barley any root

Deficiency or leaves turning red/purple due to flowering?
Deficiency or natural change due to flowering? I fed her additional CalMag and PK so I slightly caused nutrient burn. That does not indicate a deficiency normally. Thank You for any advice!

Does color change primarily happen as a result of cooler temperatures at night and lack of nutrients in the medium???

Age or Deficiency
I have noticed one of the girls fan leaves have all started turning yellow and drooping. It looks like they are turning from tip to stem and some of the smaller leaves have also started to turn. Is this due to age or a deficiency of some kind?
