Default Help please! Chilli plants, leaves brown/white

Hi all,

new to this forum, I would appreciate any help or advice on this problem.

At the beginning of February this year, I decided to sow 11 varieties of chilli plants, ranging from Habanero all the way to Scorpion Butch T. I propgated them indoors, in lidded propogatoers, and in a warm, sunny room. They germinated very quickly and began to leaf.

Once they were strong enough to handle, I transplanted them to seedling trays, and then into my greenhouse. They seemed to be doing very well, with big, green, healthy leaves.

But over the past week or so, I have been noticing that a lot of the leaves are rapidly decaying, showing black, brown or white spots, and a couple of leaves of some plants have begun to deteriorate. I have attached 4 photos as one image for you to look at.

I have put a lot of work into this crop, and am quite concerned that this is happening. Could anyone advise me what is happening to my chilli plants, and perhaps how to bring them back to health, so that I might have a good crop after the summer?

Thanks for taking the time to read this!

It looks a bit (to me) like they were sunburned. It can happen when
plants are moved abruptly from a lower light condition to full sunlight.

Thanks for that - I had suspected that it may be sun scorching. I have moved them to a slightly cooler, shaded part of the greenhouse for now, and I will keep a close eye on them.

Will I be able to move them into direct sunlight again? Or do they prefer shade?

Thanks.

Although it is advantageous to grow peppers in a greenhouse or conservatory, chili plants will thrive outside in areas of the UK south of North Wales once night time temperatures reach 10 degrees centigrade and above. Like tomato plants, pepper plants rarely withstand even the slightest frost. It should be noted that the growth of pepper plants is slow at temperatures below 15 degrees centigrade, the flowers form at temperatures of 18.5 degrees centigrade and fruit formation is hampered by temperatures over 32 degrees centigrade. Chili plants prefer a well-drained, sandy or silt-loam soil. If growing outside then stand the plants 18 cm apart in a sunny but sheltered site.

The foremost educational institution for chile research and development
is New Mexico State University (Go Aggies!) Their listing of chile
diseases has a whole section on leaf diseases here ------

Hope this helps...

They will need full sun to produce well.

Full sun--as long as you acclimatize them in slow steps.

On the other hand, the wild chiles of southwestern North America are
often found growing under trees and shrubs, where they are shaded
from the mid-day sun. (The birds "plant" them there.)
