My little lady is sick,any help?

This lady is mango. She is in a 5 gal container,outdoor.and is in ocean forest soil. I feed with an organic fert 2-8-6. It's been in the high 80's here the last few days. Anyone know the cause of this leaf curl.It looks like a paper that is being rolled into a joint ! And the tips only are dried,burnt? PH -7
Thank for any help,sugestions

from what i have read plants do that to help cool down. Its like when they bend toward the light. Its not a bad sign unless it goes on for long peroids then they dry out. If your outside it would make sense on the hotter days or week but should relax when it gets cooler out.

Mine did that as well, and now that things have really cooled off, they're back to normal.
