First Grow Auto OG & NL

12/4 - I think i let the plant purple out a little too much. Thought it could be natural at first but today i learned that it's likely a phosphorus deficiency. Apparently, when temperatures drop below 50F, it reduces phosphorus uptake. I looked up another grow diary of the seed i was using for auto northern lights from victory and saw no purple. So thank you grow diaries! Humidity is also up due to rain like 75%, hopefully that doesnt last long and is ok.
