Hello, I'm hoping to find some help with my Passion Flower.

I leaves are spotting brown. You can find a picture here:

I've had my passion flower plant for 20+ years. I started to have problems a few months back. I've been racking my brain to see if I changed anything the plant would not like. Nothing comes to mind. I also have FlowerPower hooked up to the plant to help me figure out what I'm doing. Here is my routine:

Fertilizer being used: MaxiGro (10-5-14) and MaxiBloom (5-15-14). Using as directed on bag with every watering.

LED lit for 14 hours a day.

Soil is a 30% water. I water when it gets down to 15%

Temperature is 19C (66 F) at night and 22F (72F) during the day.

I spray the leaves every few weeks with water.

Humidity in the house is 35-40%

Any help would be greatly appreciated!

Thanks!
