What happened to my chillis?

[Mcbee]

I'm growing soem Scotch Bonnet and Hot Lemon that i got from Nickys Seeds. Boh germinated fine, and i grew then in the conservatory. transplanted them and moved them out to the greenhouse.

After a few days i noticed that some of the lower leaves were starting to yellow, and some of then had gone brown at the tips, almost like they had died. The leaves have started to lose their green lustre and are now folding in on each other, along the main leaf rib.

The plants are putting out side shoots and at the moment these look quite healyhy but i'm not sure for how long!.

What can it be? I haven't overwatered them, and i can't see any aphids. Is it a fungus and should i use a copper fungicide? any help would be appreciated. This is my first year with chillis and so far its been a bit of a worry!!!!!

Is the greenhouse fairly cold at night? That would do for them.

Yellow as in too dry? Or sun-scorch? You say you've not overwatered them but how damp is the compost? They do like well-drained. Also as 2-sheds says they won't have been enjoying low night-time temps.

A picture would help.

Chilli's tend to feel sorry for themselves after you transplant them and they need to be kept warm for a few days after. Move them back in to a warm room and see how they fair up.

Have you got a max/min thermometer? They really are worth investing in, so that you can see what the highest and lowest temps have been over the last 24 hours. Over 25c and below 10c will cause problems for most greenhouse crops including peppers, chillis, tomatoes, cucumbers.

No i don't (Sorry u caught me in the middle of adding photo's!!)

The problem did coincide with me putting them in the greenhouse - so maybe thats it!

I've put a selection in the conservatory now so I'll see how the new shoots get on.

Have u had a look at the photos? do you think the leaves etc reflect the temp. differential you are talking about - or something more sinister?

Your pics don't work.

The last 2 pics don't load, but the others are fine.

I'm not absolutely sure that's what the problem is, it's just an educated guess I suppose. You really have to go through a process of elimination - pests (aphids or spider mite being the main chilli pests), too much or too little water, too hot or cold (or both in succession) or lack of nutrients.
Pests aren't so likely yet, and you'd see them if there was any.
Watering - they prefer not to sit in cold wet compost overnight, so water in the morning if at all possible.
Nutrients - MP compost has enough nutrients for 4-6 weeks, after that they need either potting up into fresh compost or a seaweed or similar feed once a week.
Temperature within the 10c - 25c range is best.
I don't think I've ever had a pepper or chilli plant with a disease!
