Purple is a sign of too cold. Nitrogen deficiency starts at bottom turning leaves yellow to top. If leaves are yellow on canopy and not rest then it is light stress. Plus .004 is really light on water. Good luck and happy growing 🌲🌲🌲👊

Dark purple areas on leaves — genes or environment/feeding problem?What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors?
I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

Purple Leaves (not purple bunds!)Noticed some purple patches forming. Im sure this happens every grow and I end up with a range of answers, but as I'm using some utes this time, I wondered if its more likely to be one answer over another this time.
Think its phosphorous deficiency?

Purple color on the leaves / FLW-Week9Does anyone know what this purple colour on the leaf means?
Yellowing is okay at this stage but I wonder whether the purpling is related to the strain or some kind of nutrient deficiency?
Thank you for your help in advance!
