cucmbers in my greenhouse leaves are turning yellow what can i do to help the plant

We haven't had much sun to heat the greenhouse recently. Are you over watering??????????

Put some Epsom Salts in your can of water and feed them, that should help reduce the yellow leaf colour. Also keep the air moist and warm. Shade the greenhouse and do not overwater

Agree with arctic, but first would also look under leaves for any aphids. Bottom leaves on mine always yellow but usually later in the season. Water greenhouse floor and keep can of water in there.

Agree with the additional comments from KEF. Very slow cucumber production ie flowers and enlarging of fruits this year - cold, dull days.

Also use a magnifying glass and inspect the underneath of the leaves for spider mite - they are tiny and you probably won't be able to see them without the aid pf one.

thanks no aphids will try epsom salts

I feed them with epsom salts at the same time as I feed them with tomato food,once a week. All in the same plastic watering can, sves doing two jobs. Also works wonders on flowering tomatoes and runner beans

 

how much epsom salts should i use,can you use to much?

The dose is usually a couple of tbsps of ES to a gallon of water.

What sort of mix are the cukes planted in? Epsom salts is useful in cases of magnesium deficiency but it's unlikely good quality mixes will be deficient in magnesium. The problem could also be a sunlight/temp issue. Cukes need as much of both as possible.
