ok I just went down and thoroughly inspected those plants. There is no white powder on the leaves. The leaves really don't have any burn marks on them except for what they came with. The leaves do though, however, seem to have color disappearing in some of them. I did notice on a few others the leaves curling up, but they are all very healthy green and kicking ass.

All of my plants are in the canna coco. I'm also using the whole canna "system" of nutes, which when explained to me are very hard to f'up feeding and over fertilizing my plants, that's why I'm spending the extra bucks on the stuff. But my plants have only been fertilized once in 9 days anyhow and watered 2 times.

Thanks everyone for your input...I greatly appreciate and respect any advise on the matter as I only want the best for my lil ones!
