Some leaf discoloration i havent seen before

mj402 · Jul 10, 2024

Is this a sign of heat stress? It has been extremely hot here the past week or so and some of the leaves have gotten these dark looking lines on them aswell as some yellowing.

I have also been using neem oil every so often to combat these Little bastard crickets that keep chomping up my leaves, but I don't think neem would be the problem. I feed them twice a week, and I just started noticing this.

Any help would be much appreciated.

How do the undersides of the leaves look? My roses often have little larval worms chewing patterns like that and they like to hide on the undersides of the leafs.

I will take a look right now, i don't do the under side of leaves as much with the neem so maybe it's time for a good spray to the underside

I don't see any bugs on the undersides of the leaves but I gave them all a good spraying of neem oil on the top and underside of the leaves. The only bugs I've really seen on them this year is crickets/grasshoppers and spiders.

I may put another layer of diatomaceous earth on top of the soil too.

How do you mix your neem oil? I sprayed a male plant I had outdoors and burned the shit out of it. I read that you shouldn't spray the top surfaces of the leaves for this reason as well as potentially inhibiting photosynthesis to some extent.

It’s a leaf miner, they normally don’t do too much damage, mostly cosmetic. Neem will kill them.

you have some leaf driller. it's hiding somewhere

A leaf driller huh? I'll have to try to find what those are. I buy captain Jack's neem oil spray that's what I use. I sprayed them the other day but still noticed some more leaves looking like that today. I also found this patch of white not sure if it's powdery mildew or some sort of webbing but I am keeping an eye on it. I have been removing all the damaged leaves.
