Wtf is happening here

Boulder bubblegum under 600w hps in second week flower using batmix soil and water ph'd to 6.5 all other plants are thriving this had a stunt then this weired shit started happening really fast. Amy ideas need to sort it fast. It's happening all over the plant on new growth.

You have a picture without the HID on bro? Kinda looks like a boron deffenicy to me, but can't really tell yet.

I can't tell from that picture. Personally I'd just do my normal 'try to save it routine'; Flush, then on last flush use anti-stress supplements, b vitamins, Epsom salt (or a tiny bit of cal-mag). Then make some foliar feed spray containing all the micronutrients you can, and spray the leaves a couple times a day.

Tbh it doesn't look like a very common deficiency, but perhaps one of the micro-nutrients. Like the guy above said maybe boron; but also check out calcium, magnesium, copper, etccc

Turn hps off and take a pic in natural or blue light.

I've been changing my camera on the phone to incandescent inside the hps tent...works good

Yeah I was thinking it looks like a boron def but I don't see how there's plenty in the water roumd here ph is bang on other plants are growing very vigorous and look ace I've already flushed but will flush again with some cal mag.

Anyone else any ideas

As everyone else says picture without you're light on my man..

Here have a look

i would say that looks like broadmite damage any bugs around? check the newest growth underneath this is were they attack 1st

This is the only plant affected and I've already sprayed twice with resolva just in case I havnt seen any bugs anywhere

The second biggest problem here is all the new growth looks cooked. So when you solve the biggest problem ( figuring out what the cause is) that stem won't grow. If solved quickly the best you can hope for is the same results as if you topped it today. Your best bet might be to put it out of flower and cut it back. That will remove the worst of it and put it back to veg. and start over with it a month from now.

If it's not bugs or disease? Did you use a magnifying glass and look on the underside of the leaves? Are your reflectors creating a hot spot? Is the airflowing evenly across the entire canopy?

I can't comment on your soil I don't know a thing about it. I use a soilless mix so I know exactly what is in my soil. It's real simply for me if I didn't put it in there it's not in there. When you use soil with nutrients pre mixed it will take time to figure out if there are deficiencies and how to address them. This can be very strain specific. Are all the plants the same strain?

I have no idea what caused that, but at that point I would personally just toss it. It's possible it has some kind of infection viral/bacterial. The way the leaves are twisting looks worrying to me (looks similar to a viral infection), but it could also be from how badly the leaves are disfigured. If you have a number of healthy plants, I recommend tossing that plant, and the soil and never reusing it.

I've only seen something similar to it once, and that was a viral infection (TMV) I didn't know it at first and tried to save it, then all my plants ended up getting it... Like the guy above said; best results it will be stunted for a while, and will act like the plant was simply topped at that point. Worst case - it's something contagious be it bugs, bacteria, or a virus. It could even be a genetic mutation, but idk.
