Does anyone know what this is?

Only 1 plant is showing the symptoms. I spray them once a week with azmax and neem oil so the plants look bug free.

Im in coco and the PH is 5.9 (Im in bloom). Im worried this plant will infect the rest. Bottom leaf is dying but its an old leaf. The new growth, some of it looks strange.

Thanks for all the replies! Too Kind!

But on another note, ill put myself on blast so hopefully another new comer can learn from my mistake. I went over all the plants tonight and noticed symptoms that showed over fertilyzing, including the 1 above, friend said it looked like a PH issue. I always feed at correct PH though.
So I dont get run off when I water (in coco). I know thats bad but I had some mental block and thought I was over watering all the time. So basiclly I got some run off tonight and checked. PH was way off even though I feed at the correct PH. The ppm is litterally around 5000 in the run off!
2 weeks ago when I flushed before bloom the run off was 700ppm.

Im surprised theyre still alive. Point being, you want run off water. 15-20%. Nutes built up really fast, 2 weeks in bloom. Im gonna do a major flush as soon as they dry from the last feeding.

The strange curling is probably from the neem oil. Your not doing yourself any favors using it every week. It can clog the pores of the plant and hinder transperation.

If im not mistaken neem oil is systematic. Once you have sprayed your plant, it absorbs it and the benifits still occurr for the duration of neems halflife.

Also raising your lights after sprayijg it is a good idea.

Something for you to also bare in mind is that runoff pH in coco will never be accurate.

You can base your feeding strength on the runoff strength as a general check but the only true way to test your cocos ppm and pH is with a 1:1.5 extraction test.

What's probably happened to you is that K has probably become toxic causing uptake issues with other nutrients.

K is generated naturally in coco anyway and without getting runoff its just got worse.

Make sure if you flush coco that you instantly run some feed through them otherwise you could exacerbate the issue with reduced osmotic pressure in your rootzone.

It's hard to tell from the light, but some of the leaves look like they're a very dark shade of green, burns on the tips and under cupping of the leaf which is a sign of over fertilization.
