Hi! I have a relatively new-to-me "Improved Myer Lemon" tree. It had beautiful blossoms on it when I got it and it seems that is health has been stagnant/decreasing over the past few weeks. It did produce several blossoms additional, but less. On the plus side it does seem to have some forming lemons (I think?). We have repotted it into a larger pot (but definitely could have gone bigger) some potting mix. In the first several weeks all we did was water and cultivate into the soil some coffee grounds (we have water ~9pH). Otherwise we have watered it ~weekly and cultivated in some citrus-specific fertilizer (per the box's young-tree recommended quantity - taking the small side of the range) last weekend with watering.
The reason for my thread - I fear this tree is not getting exactly what it needs. The leaves are yellowing and some are falling off Today I noticed much larger sections of the tree are showing yellowing and I'm hoping to stave off whatever is going on! I was searching and some photos indicated lack of manganese.. would you agree? What would you do given how this plant looks?
