Hi all. This is only my 2nd year growing and my 1st year of supplying nutrients. My Sour Tangy is currently showing the following problem where the lower leaves are turning yellow. My initial googling was suggesting that it's a nitrogen deficiency. I give 2Tbsp EarthJuice Grow and 1tsp EarthJuice Bloom served weekly. My current day length is 14h in NorCal. I was thinking I'd switch to more bloom once the day gets into the 12hr range. Some more googling was suggesting that it could be overwatering, so I removed my drip line but things haven't turned the corner just yet. Any recommendations? Thanks in advance.
