One side of the trees appears whitish around the flower and slowly turns completely white , then dries and kills the flower. It’s spreading slowly. It only appears at first flowering stage and only one side of the tree. It almost looks like got hit excessive cold leaving leaves burned.
Please help before this aggressive attack ruins the whole tree.
Did you just put it outside? I’ve had that white bleaching happen taking a plant inside to outside. It was in veg and grew out of it.
potassium deficiency can cause this. To much water makes it worse. Welcome to OG.
Thanks for the tip. I’m convinced it’s lack potassium and too much water. Great advice thanks again Heliosphear.
I would go for Sulfur, watching where the yellowing starts, don’t see the typical Potassium deficiency blotches and burnt leaf margins … 
Thanks George, I will also try Sulphur. I fed my plants organic compost which has lots of banana leaves. Since I’m new to this I will learn a lot from members here. I really appreciate the tips!!
It appears that 2 plants are both having a nutrient problem at the same time, in my garden I would consider this to be a pH nutrient lock out. The chance that the soil is actually deficient of nutrients is almost zero.
