Burnt up plants

Yesterday I noticed some of my plants had black leaves. Not sure what I did and I’m trying to figure it out . I’m thinking it may have been from me spraying them with neem max. Yesterday morning I was working on my blue dream which was completely fine. A few hours later I find it with black twisted leaves. Anyone experienced this problem? Trying to figure it out, so I don’t do it again.

before i ask anything else, how is this plant watered?

the 3 plants with this issue are watered by hand. Top watered ( I have some on self watering planters that have no issues) 2 of the 3 are in the ground and usually don’t need much attention. The 3rd is in a 10 gallon pot.

Did you spray with the sun shining?

looks to me like you had neem or some form of water feeding sit in the plant leafs causing the burn, that just me opinion tho

Neem is the most likely suspect. I damaged some of my indoor plants by spraying them. It’s not just a problem with plants growing in the sun. If you want to verify that neem is the culprit, you can test spraying it on a small part of an undamaged plant.

also if it turns out to be neem, you have a few options, spray under all the leafs thats where most of the issues are anyways that neem deals with, if you are gunna get neem on the top of the plant do it when the sun goes down or grow lights turn off, i always mist clean water after on the tops of leafs to wash the neem off of them.
