Plants struggle to uptake nutrients below 10°C - particularly phosphorus. Also worth noting the adverse effects for plant growth will be more prominent if the swings between day and night temps are significant. The drop in temps is also associated with purple petioles and stems, as it is with a pure phosphorus deficiency, suggesting . The foliage can develop a darker blue tinge-like sheen however your leaves maybe have skipped this step with the lockout/deficiency escalating so quickly. I would also suggest that the heavy bloom feeding during a lockout would have caused a cascade of issues, where pH swings and EC spikes are a likely outcome. They don't look so bad to me anyway, you might just have an odd growing pheno and that's the end of it ! Good Growing

Holaaa! Your information is very accurate, plants at low temperatures tend to show dark colors up to purple tones, so every time they have light, they absorb it much better with this dark color... also, watering with a fertilizer high in PK tends to produce lilac and purple tones! I've seen this in several grows and in relation to what you mentioned about PK.

Super common! Happens with a lot of genetics with colder night time temps! I love it, but the THc tends to be lower because the plant is kicking into a different mode
