Looks like calcium maybe a ph issue ?Three plants in 12/12 for a month. 400 watts spiderfarm led, foxfarm soil, perfect nutrition. Dry, crispy, and withered. This prob keep erupting on the plants' sun/shade leaves, working its way up on the plant. I have sprayed with NeeView attachment 2360742m oil. Should I use copper????
Neem oil will leave a residue that will burn the leaves from the light. Mist with water and dish soap, dawn is best i think, then rinse soap of by misting again with water, lightly shake the main stem to shake off excess water, use a oscillating fan to dry. Cal/Mag is usually a good add if you aren't using it.Three plants in 12/12 for a month. 400 watts spiderfarm led, foxfarm soil, perfect nutrition. Dry, crispy, and withered.

brightest intensity, temps stay in 70sOut of those 400 watts, how intense is the dial set? And what are your room temps?
100% intensity, how far away from the tops?brightest intensity, temps stay in 70s
8-10 inches. There's no burning of hairs or leaves up top though100% intensity, how far away from the tops?
Okay. Some strains freak out with that much intensity.8-10 inches. There's no burning of hairs or leaves up top though
this is a disease, pretty sure. if it were nutrition, it'd be all over the plants, burning would be mostly at the top. That's why I asked about copper.Okay. Some strains freak out with that much intensity.
Can you post a picture of the whole plant? That would give everyone a better idea. It’s hard to tell from clippings.this is a disease, pretty sure. if it were nutrition, it'd be all over the plants, burning would be mostly at the top. That's why I asked about copper.

Yep! Never use Neem oil, and if you do, add an emulsifier (i.e., dish detergent and water).Neem oil will leave a residue that will burn the leaves from the light.

Not likely.this is a disease,
Nope. The plants move mobile nutrients from the lower leaves.if it were nutrition, it'd be all over the plants,
Not necessarily. Older leaves have been exposed to the light for a longer period of time, so they can show light stress/burn before the top of the plant does.burning would be mostly at the top.
Copper deficiency is rare.That's why I asked about copper.
Too close, especially at 400W. I recommend both moving the light up 18 to 24 inches (if you have the room) and setting the dimmer to 50%. The plant is flowering, so there won't be any new growth, plus those damaged leaves won't recover. It can recover some, though, and there's enough green to get it to harvest.8-10 inches.

All that said, I would agree with those who recommend calmag and reducing the light intensity.
