cucumber problem

hello all, ive got 1 cucumber plant which i think is a marketmore, it grew fast and is really tall its in my plastic greenhouse atm, it used to live inside on a warm sunny windowsil and it got loads of little cucumbers on it which were all growing well but since its gone outside lots of the smaller cucumbers have gone yellow at the ends, ive only had 1 cucumber which has grown properly i cut that this morning as it was getting quite big, i feed the cucumber with tomato food i normally only feed them once every two weeks though should i feed more regularly? i feed it with tomorite when im doing the tomatoes.

the leaves look healthy on most of the plant but at the bottom the few leaves there look brown around the edges, am i best to take them off or leave them? i took some of the cucumbers which were yellowing off the plant.. do you think it will grow anymore cucumbers or not?
