As Littlefoot has already said the diet you are feeding is really not good for your tortoise, the products you list are either too high in oxalic acids (which inhibits calcium absorption) or of no nutritional value. Have a look at this link for a good list of edible plants/weeds:

Diet and healthy growth

If you really need to supplement with supermarket products then go for things like watercress and the Florette bags of leaves which have a really good mix.

Why do you not feed her one day a week?

the pet shop told me when i got my 1st tortoi to have 1 day off a week from food, he seems alot better today so it must have been something he ate as he is running around as normal, he is a bit lighter though, an he is eating well now, think he was just poorly for a day or so.

I'm really pleased your tort is okay now but please do some reading on what diet you should be giving them - every day. This article is a good starter (scroll down for info on feeding med torts):

Yes please change his/her diet as the one you are providing is bad for the tortoise !

is there anywhere i can buy these weeds from?, i'm not really a flower person, i recognise dandylion and have given them some but thats about it, i recognise the need to change the diet but I dont know where to start

There are lots of weed seeds on ebay... just put in a search of tortoise seeds

Advice on here is plant them in deep tubs and neglect them... I'm useless and couldn't get any to grow.

There's quite a few easy to grow things you can get as well like roses, pansies, geraniums, cactus, hebe (flowers), strawberry plant leaves (only new growth though as older leaves become toxic)... just be careful if you buy any plants that you replant by knocking off all the original soil and planting into top soil then waiting for new growth before feeding as they will most like have been treated with pesticides.

Dandelions are a good start though

I only feed my torts weeds, I never give veg, fruit or unnatural dried food!

i've downloaded those and printing them out now, they do like the dandylions !, are you supposed to give them different weeds every day, or is it fine to give them the same for a couple of days ?

Variety is always best, I try and give mine 3-4 different things a day. But the same thing a couple of days running won't do any harm.
