New Grower In Desperate need of some advice

Hey All

It's great to be part of this online community. Another first for me. I don't have an allotment but I am turning my balcony into growing hive (well if the sun came out I would). So at present most things are getting too large for their pots on various window sills!!

 I don't know if I'm being paranoid but I am a little concerned about some of my veg. My Courgettes started off really strong and have plenty of leaves and trailing all over the place. However their first set of leaves and the odd newer leaf have curled, mouldy looking edges. The rest of the plant looks bright green and strong with many other little leaves looking ready to form. I wasn't sure if this was something to be concerned about or maybe they are too moist (being in the kitchen) with not enough full sun (being in the UK at present).

So i haven't been freaking out too much about that, but this morning I noticed some reddy brown spots on the soil of the plant and now thinking this might be serious. especially as the roots are so close to the surface (I realise they are ready to plant out but as my balcony is west facing and its been so cold and windy I'm too scared to do it yet)

Also my cucumber looks very sad. Both leaves have big white mouldy patches through the leaf. I'm thinking maybe their isn't enough air circulation in the kitchen and when I cook it gets quite steamy. There is another leaf coming through though so not sure to leave it and will it cure itself. Or remove the mouldy looking item from the plant...

Any help advice would be greatly appreciated its started to keep me up at night!

Thank again

Sounds like a humidity problem. They want fresh air but not a breeze or draught. Cut off the affected worst leaves and burn or dispose of in  the bin. Add some barely moist compost where the roots are showing.
Not enough light either.
To maximise sunlight make a back-screen reflector, just some kitchen foil shiny side out behind the plants so the sunlight bounces back onto them. Stick some on empty cereal packets , use whatever you can think of.
Sow a few more seeds just in case, its not too late, you might lose this lot.
Try and move them away from the humidity, even close the curtain whilst you are making it steamy, protect them however you can.

Good luck.

A piccie would be really useful 

 Hi ya

I've got some pictures to go with my post. Brought my tin foil and will start removing the ill looking leaves. Do I need to cut them in any particular way to cause less stress to the plant?

Thanks again
