I have 3 cucumber plants that I started indoors from seeds. They were all off to a great start but after producing 1-2 cucumbers I noticed the don't look as healthy and leaves have turned yellow. I see new growth in some places. Is this normal? Are we at the end of cucumber season? What should I do differently? I am in San Francisco area.
A lot of things could be happening. Lack of nutrients or too much fertilizer. Could also be the ph. Test the soil. Cucumbers like a ph of about 5.5. I would also put mulch on the ground around them so the soil stays moist for a longer period. The ground looks very dry.
