Hi, this is the third gardening forum i've joined as so far nobody has been able to offer any real advice that has been correct or solved the issue, even my local big garden centre is clueless.
I decided to grow Sweetcorn this year (Incredible F1 variety) and Butternut Squash. The Squash is doing great by the looks of things, the sweetcorn isn't. It was growing absolutely fine to start with it, some are in large pots and the majority are in the ground, however about 2 weeks ago the new growth started to suffer what appears to be chlorosis, yellow stripes, it's all across the leaf and is not consistent with Nitrogen deficiency which was first suggested.
The newest leaves and shoots are almost completely white! Growth is now extremely slow, almost halted. The only other visual clues are the very edges of the leaves appear to have a red border, it's a very very thing red border and isn't getting large, alos there is slight puckering at the edges of leaves.
The latest attempt to fix it was Epsom salts thinking it might be sulphur or magnesium deficiency, so far it does not appear to be helping at all, all the large plants are affected and younger ones are getting increasingly so. The only pests I can see after very close examination are greenfly which I squish and their damage is clear and seperate.
