My cucumber plant is turning pale and blossome dropping off
I'm a newbie in gardening. i started growing the cucumber this april and they were growing well.
3 weeks ago, the plants start to have male flowers buds and i have found some female flower bud since last week.
however, the many of the male flower buds drop off before it opened. And i found my plants are getting pale.
what's wrong with my plants? am i watering too much or less or the sun is too strong? Please help!
