What are these white splotches on my leaves

It could also be thrips, they leave that white stuff on the leaves too, thier poop. Check really close for tiny little bugs, under the leaves is where they like to hide. Thrips are hard to get rid of too. Or it may be the powdery mildew as previously mentioned, but hard to tell from the pic. Good luck. :mrgreen::peace:

I suggest you use neem oil on a schedule to prevent this in the future. I don't know how well it will eradicate thrips, but you have to use something and neem is organic. I've also heard good things about Nutrilife SM-90. GOOD LUCK INDEED!

Ya looks to me like powdery mildew. Sulfur burner or some sprays will help with it. Ive never used neem oil. But i have used sprays like Safeguard or biosoy. Make sure its the ones that say for powdery mildew if thats what u determine it is.

Wiper your finger across the top of the leaf , does the splotches come off? if so it's most likely Powdery Mildew, If there is white to yellowish speckles impregnated into the leaf then it maybe mites or thrips check the underside of the leaf for pinhead size crawlers aka "the borg" as I would call them heh they multiply fast....

Instead of neem oil, you can mix up a spray yourself. Take a clean spray bottle, cover the bottom with dish soap, fill 3/4 with water and the remaining 1/4 with white vinegar. Shake it gently and spray all over and under the leaves unitl all covered (not soaking though). Leave that on overnight, then rinse off with clean water in the spray bottle. This should kill them and make your leaves shine, lol. You may need to repeat in 2 weeks if still seeing the white stuff. This solution works on aphids, spider mites, thrips and gnats. Good Luck. :mrgreen::peace:
