Should take them out little by little.In fact these plants are like babies (our babies, right?), you don't let a baby outside in the sun to be burned.
You can use the shadow nets at noon, when the sun burns.
I would not remove the leafs.
ok, thanx. I dont think its the soil or fertilization since that is the same as before, but this started 2 days after moving them out. So i will have to get som shadow net to use in my greenhous.
