Buds rapidly drop from plants without signs of fungal infection.
Control - Maintain adequate water especially when temperatures rise dramatically or when light level suddenly increases. Plants may be especially sensitive to dessication when conditions change from cool and dark to hot and bright as can occur during the spring months. This can result in interveinal chlorosis of young foliage. As deficiencies become more severe, necrotic spots will appear within the chlorotic tissue. Application of the appropriate nutrient to the soil or potting medium will correct this problem, but plant response tends to be slow.
