cucumbers going yellow

[daveylamp993]

I have grown cucumbers with great success over a number of years,this year the cucumbers are forming,grow to about 1 inch then start to turn yellow and eventually die and fall off the plant,or I pick them off and dispose of them,the plant look healthy enough,they are watered every day,not copious amounts i give them half strength tomato food once a week has anyone got any ideas as to what I am doing wrong,many thanks.

They are probably not getting pollinated.

What variety? Indoors or outdoors?

I think your problem is the feed, tomato feed is high potash or at least should be while cucumbers require high nitrogen

[daveylamp993]

They are a indoor variety,i have noticed this evening that some of the lower leaves are slightly yellow veined,i have got some blood,fish and bonemeal,would that help ? I will try to get some dried blood if that will help,many thanks

What would you suggest as an organic feed for cucs. I have been doing the same as Daveylamp.

Hi Steve 
I have never used any organic for cucumbers so i cant really recommend what i have not tried, also i think they are a bit expensive.
If i was to go that way then i think i would look at using a poultry fertilizer put into a 45 gallon drum so it breaks down and becomes a soluble feed.
There would be no waist as what is not put in the water can go on the ground.

Manics just brought one to mind Maxicrop Comlex has a high nitrogen content of about 7

We use seaweed and our own comfrey feed for all fruiting plants. Seaweed greens them up well. You can get organic tomato feed for your cucs
