Problema fogliare nelle piante

Yeah, you've kind of cooked them - but it's not without hope. I would start by cleaning up the mess, getting rid of all the dead leaves and throwing them away. Then just be gentle with them, recognize they're going to need a bit of time to recover - but I DO think they'll recover. I've never found neem oil to be effective at anything, to be honest... waste of money. For leaf sucking insects, I use either Dr. Zymes Eliminator or Spinosad... for leaf chewers, I use BT (bacsillus thuringenisis) they're all organic and can be used straight through harvest whereas neem oil really shouldn't be applied on the buds themselves... and always Always ALWAYS spray just before lights out so the moisture doesn't act like a magnifying lens and your leaves are burned by the lights... Don't give up.... this WILL come back... and if you just get rid of the dead/dying leaves, she'll LOOK a lot prettier (and I swear, plants LIKE to look good!) It will give both you and your plant a boost in morale! Good luck....
