New Guinea Impatiens with leaf cupping and tip burn

Greenthumb -

Thanks for the picture. It does help us get a better picture of what is going on here.

The leaf rolling is difficult to see in this image but there is some downward cupping of the lower foliage and some tip burn evident. The leaves are also very narrow. These are all indications that the plants have been allowed to dry too much at some point. New Guinea Impatiens express some pretty clear indications of moisture levels. When they are kept moist, the foliage will be large and lush. Kept too dry, and the foliage will be thin and narrow with tip burn and yellowing of the leaf edge.

pH and EC levels are within good range so our recommendation would be to evaluate moisture management practices and make sure the plants are not being allowed to dry too much.

You mention in your email that the first chemical applications were made this past weekend. What was applied? If the plants were already stressed to begin with when an application was made in can sometimes exaggerate the stress the plant is under.
