What Causes White Marks on Plant Leaves
Hi Judy, i have attached 3 pics in the hopes you might be able to tell me the problem. Thanks in advance.
From the picture it looks like your croton is getting burned by being in the direct sun. The plant likes very bright lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light., but not any direct sun. If you think that this could not be the cause, please let me know and I’ll suggest some other possible reasons.
