on a legal medical grow the panels, (one veg, one bloom 240w blackstars) are roughly 16-18" above several plants, two in coco, two in fox farms, and two dwc..

all of the plants are stunted, all of the plants have dead foliage.

Ph is good, temp is good, ppm is good.. several of the plants have white patches on their leaves, like all the color has left. most of the plants cotledons have dried up like a nitrogen defficiency... they have been treated with micronute foliar sprays.. canazyme, rhyzotonic..

does this sound like light is to blame? it doesn't seem like it should do this, but it's the only answer i can think of.. does anyone have some good photos of light bleached leaves?
