please can some help..I was a very chuffed  bunny newbie gardner as I "had "healthy french bean,butter nut squash,courgette and plum tomato seedlings in green house, potted them all up,even talked to them !! well unlike my kids they didnt answer back lol and hardened them all off (as per advice)for several weeks before eventually planting out with tender loving care, my french beans are in main veg plot,plum toms in side plot and everything else in v large pots, had no frost on them,no cats using as a toilet !! watered,slug pelleted u name it  but  they have developing a wierd looking leaf problem..they all appear to have leaves that are "drained " of colour and very dry and leather looking!! the beans more so the leaves nearest the ground !! very bizarre!!
any help/suggestions/solutions would be most gratefully recieved

Until recently we had some quite cold nights, albeit with no frost. It could be that. Whilst frost will see them off, they really don't like cold weather and they will sulk and could takes ages to recover.

These tender plants really should not go out until the nights are reasonably warm.

hmm puzzling they are planted next to spinach, kohl rabi and ruby sprouts... could you define warmer nights, what sort of temp are we talking ? im planting fresh beans to replace gonners would a fleece over others help ?

I would like to see night time temps of at least 7-8C before risking beans, tomatoes really need 10C.

The other things you mention are much tougher - not all plants are the same, you have to make individual allowances. Sprouts will stand most weathers.

The nights are warmer now and I suspect fleecing them would be like shutting the stable door after the horse has bolted!

It could be the result of bruising from wind.

Definately the cold - speaking from experience 

I planted my runners and climbing french beans out last Sunday as they were fighting their way out of their pots and clamouring for the greenhouse door.... only to hear on the weather forecast on the Monday that frost was forecast for the Tuesday!   

They all went pale with a few crusty leaves, just like your description, and I thought I had lost them, but what a difference a couple of days sunshine makes!  Checked on them this morning and already they are all colouring up again and producing new shoots.

I haven't risked planting out the toms yet though, although I may be tempted some time this week.

I agree, it's most likely the cold nights. They should recover, given plenty of sunshine and no frosts

could try giving them some epsom salts?
