Hello,

There is a bit a nitro def in the lower area, but that's expected. To me, it looks as though it's receiving a toxic level of ...'something'. I somewhat suspect that you're ph readings are off and giving you a higher reading than what is actual, meaning that your soil might be leaning too much towards the acidic side. I think perhaps pull back on what you're giving it, let your ph swing a little. This far in the game, the fan leaves should have enough juice to carry it to the finish line.
