why are the leaves like that

I was using AN sensi coco ab. It's been like this since the last time I gave food. I looked at leaf diseases but couldn't find anything similar. I'm afraid it will get worse. I took a photo immediately after the lights went out, what do you think is the problem?

Looks like nitrogen toxicity

I'm sure I've given everything in the right amount

how do i fix it

IF it's nitrogen toxicity you'll need to flush the soil and start over with a lower dose of nutes. Another tell tale sign you'll see soon is the tips of the leafs burning if it's nitrogen.

can this be something else i am using cocopeat and i gave everything the right size

Its overfed like said above. N tox.

Are you using a TDS meter to measure the PPMs in your nutrient solution, or are you just following the directions on the bottle? If you follow bottle directions, you'll burn your plants almost every time. I agree with the above, too much nutes, nitrogen toxicity.

I have always followed the instructions on the bottle so far, this is the first time I have such a problem. Is nitrogen toxicity a huge problem? How can I best cure this plant and will this delay the harvest too much?

Huge problem is when pH and eC are not in use.

Plenty of clean water and next time start slowly half of dosage.

Imo never exceed one half the dosage on bottle

thanks for the help. I'll wash the pot and wait for the next watering. Do you think it greatly affects the duration and amount of the harvest? Oddly enough, I have another plant of the same age from the same seeds. I have watered him the same way until now but he is healthy

It's all depends on strain some of them like more others don't.
That's why chart's are not always accurate.
It's good to start with a half and slowly go up.

Flush it out and keep calm.

I'd check pH first.
