Just came across this grow. My friend if possible try to lower your ph to 6.0 to 6.3 this would be better for your plants to use the nutrients better. The other is something you can't control is the temperature is so high you would need a very high humidity to keep her happy. She is suffering from VPD (vapor pressure deficiency) so she's trying to conserve water in her leaves that's why they are curled up in a canoe shape. This causes less transpiration from the leaves meaning Her stoma under the leaves are closed not taking in as much Co2. Shes also not drawing as much water and nutrients through her roots. You can trying to use a 1/4 strength foliage feeding a couple of hours before sunrise or late in the evening after sundown. Hopefully you can catch her with her stoma open. Try to get her a couple of times a week with a very fine mist sprayer. Don't spray her in direct sun light you'll burn her leaves. Good luck you have a very difficult growing environment to deal with.
