Yellowing leaves and yesterday curl down leaves after watering

Hi. The dropping leaves after watering look like your roots are drowning. How's the drainage in your pot? I'd let it sit out a few more days without additional water and check if it gets better. Can't say much about the yellowing of your leaves BUT if it starts from the bottom, than it's a mobile nutrients deficiency or overfeed (N, P, K, Mg or Ca). The yellowing of lower leaves is normally a Nitrogen deficiency. I'd add a bit of Nitrogen but in very small amount and check if it makes any difference. I'm crossing my fingers for you, buddy ;) XOXO Cremo
