mushibu10(zone 8 (UK))August 13, 2014

the plants. are grown in a grow bag in an unheated greenhouse. they're watered daily

they started to go yellow at the bottom of the vine when fruit first set. I feed weekly with a basic feed (cheaper miracle grow (wilkos own make)) I hqve given blood and bonemeal In the hope it's nitrogen deficiency.

thw melon variety is Jubilee

If these were house plants I would say you are over watering,

that very well may be also, and most mildew is also a result of far to much moisture...there are a at least two other gardeners that have mildew infestations, as yet i have been very lucky and have not yet had to deal with mildew. i have slugs and earwigs...eating my poor pumps. a mildew is a coating on the leaves, and your leaves look as if the discoloration is internal, part of the flesh. is there a dust or spore from the leaves when you touch them or pat with a white towel?
