Hi all. I am about 3 weeks into my first cannabis grow. About 1 week ago, one of the plants started developing yellow leaves. I initially thought it was likely related to flowering, however it is beginning to seem more systemic. The plants are in a 4x4 tent with x4 LM301H panels. I feed everyother day with peak harvest grow and bloom nutes, with liquid bone meal every other feed, and yucca extract. Growing in soil with ph of 7ish.

Based on what I've seen online I am curious if it could be a magneisum or potassium deficieny. Some plants do have a bit of a red stem which I read could be related to low nitrogen. Perhaps too high of ph? But, I am very new to growing as I mentioned earlier, so I would love any feedback! I was feeling pretty good about my first grow but this is prettty discouraging.

Thanks in advanced!
