If you have rain water use that - flush it very thoroughly - just keep on for a while.
Then let your plant rest a bit from the hard sun. Leave it away from direct sun for 1-2 weeks - until healthy and growing again.
Hope it helps
I dont think its the right time to put it out in the hot sun. The plant is stressed from u burning it and to compound the prob your going to stress it more. She will think u dont like her. Try to get it growing healthy again first then start it in a shaded area.
