Is this due to the sun and hot weather?

Some parts of some leaves are looking like they're burnt or something. Is this due to the sun? Or do I have another problem? It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)

If you let the soil dry too much the plant starts uptaking more nutrients so that may be the issue, overdrying rather than overfeeding, try adding some straw or hay or whatever plant material on top of the soil to keep the soil more chill.

She has signs of both P and N toxicity, unless you supplemented with a high dose of these recently, then its defenitly from underwatering (soil being too dry) more heat= more need for water.

Yes, my friend, when the tips of the leaves are curling upwards, it means that the sun is negatively affecting them as the plants are trying to hide from the sun. I recommend keeping the substrate moist so that the temperature inside the pot stays "low" and moving it to the shade at certain times during the day.

That's over feeding, also called nutrient burn (burnt tips and edges). See how dark the leaves are? that is not normal, leaves should be light green, not dark, that's another symptom of over feeding. Stop feeding it, and give it plain water.
