Very cold temps (<16C) can cause purpling. However, such cold temps will also stunt the plant and reduce yields.

There's a culture of ignorance around purple plants. Some ppl have the idea that they are unusually potent. Purple buds are not usually a good thing, normally indicates nute deficiency (P) or burn (K) or excessively cold temps.

There are genetically purple plants around which come up purple in proper conditions, but they're very rare and not usually the most potent strain.

Yes, that's probably a P deficiency. Could be caused by an actual lack of P or a pH error.



As you see from the chart, P is locked out below 5.8.

Here's another one, not sure of the source, not as readable as St0ney's. I think St0ney made up his chart from this one.

Looks like necrosis related to the pH being shot too low. That looks like the older growth, though. It won't repair. You're only concerned with the new growth. If it looks fine, you've fixed the problem.

I think the roots might be a bit cool since that is a completly different temp. That also cause purple stems, and stunted growth.
