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 Nee

Looks like calcium maybe a ph issue ?
Its very hard to diagnose in my opinion
Got some plant pics?

I dont really know what the neem oil is supposed to do but cut it in flower

And im going to need some more info on your watering schedule, Temps and RH

Out of those 400 watts, how intense is the dial set? And what are your room temps?

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.

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.

Can you post a picture of the whole plant? That would give everyone a better idea. It’s hard to tell from clippings.

rust is a disease
Dont put shit onto your leaves i dont even let water on there
Its a breeding ground for this bullish

If you belive its a disease keep her clean
Remove effected foliage

make sure there is proper ventilation and humidity ao water driplets dont from on the leaves during dark hours

Looks like light burn, the red/purple color on the largest leaf could be that, or as you say a mineral deficiency. If it is copper, throw some nickles into the bottom of your watering can for a day or two, then use that water as you would. It wont add enough to hurt it, but it might be enough to re-balance it. Less invasive than adding store bought stuff.

The entire plant would not be affected all at once. The older fan leaves, and fan leaves from the main stalk will be first to let you know something is wrong.. They are also the leaves that will be cannibalized first to supply the missing nutrients, thus showing a dramatic drop in leaf health on only certain leaves.

If you're at 100% intensity then your plants are probably going through calcium and magnesium like a mofo to keep up.

That light should flower your plants without even getting near 75%, dude.

Too little potassium or too much pythium, maybe both.

Pictures of the plant is the only way anyones gonna know. Need all that context in order to examine and diagnose. Could be nutrients. Im doubtful its light burn, but could be. Spraying with neem oil is only ok if theres a bug infestation, which it doesnt look like thats the case but cant tell for sure by just that picture.

here are pics of the two most affected plants

Yep! Never use Neem oil, and if you do, add an emulsifier (i.e., dish detergent and water).

Not likely.

Nope. The plants move mobile nutrients from the lower leaves.

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.

Copper deficiency is rare.

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

8-10 inches.

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.

If you’ve no bugs neem oil will do nothing bar leave a horrible taste as it doesn’t wash off.

wow 😮 that’s a lotta bad information
It’s a disease, oh my goodness, I’m gonna be laughing for days

It’s never going to be a single element like copper unless you’re making your own nutes & medium even then…
Why these folk come out with this stuff idk
Normaly there it’s a boron issue folk
