That looks more like N deficiency to me, than nute burn.
When I get nute burn, the tips of the leaves brown, and get crispy.
I use scissors to cut the burned tips off if its a plant your size. If its smaller, I don't do anything, and the plant usually is fine.

Your bottom leaves are yellow, and the entire plant looks a bit light colored.
If I was you, I would add a little nitrogen, and see if it gets darker in a couple days.

I think the flash on the cam makes them look a different color to what they are, when there in daylight they look abit darker, what convinced me id give them nute was they were fine until i mixed the nutes wrong then i went up the next day to all the bottom tips were burnt then since then the leaves just seem to be dying away but the rest of the plant seems fine there growing nice, i appreciate the comment though, i look foward to learning from my mistakes and improving, so would it hurt to add nitrogen? Just in case, even if it didnt need it would it still be benificial to the plant?

I'm with pro human, looks like N deficancy,

What are you feeding them? And what did you burn them with??

burns usually happen up top, and your yellowing from bottom is almost always N def.

To answer your question:
I always cut burnt leaves out so I can easily spot a new problem,
BUT, if you cut those off and it's N Def. Your plant will just go to work on cannibalizing the next ones up,

The plant looks OK.
Worry less, and keep doing what you are doing.
Even with the new pic, it still looks light to me, so give it N rich fert.

It looks like you fed to the point of lockout, which resembles an N deficiency. I would recommend just watering for the next few times and then get an even nute mix...I use DG nutes (dyna grow) and it's 20-20-20 for veg although I have yet to go full strength...peace and good luck...

No...
Theres always a "Maxed Out" effect whenever you overfert to the point of lockout. The foliage will look amazing for a day or two, but then you'll notice them start to get waxy, utterly dark green, claw and then finally the burn will show on the serrated portion of the blade. That's when your plant will enter into the dreaded lockout. I agree with the others before: they're underfed. Keep your ph in line and simply boost the feed concentration moderately

Lock out can actually happen under many different circumstances. Not all nutrients lock out like the next.

In fact Google nutrient lockout. You'll find vastly different looking plants symptoms

Hey thanx for all the replys guys but like i said before the flash on the cam causes the plants to look a different colour, my nute plan is fine, i havnt just gone to a shop and bought the first nute available i had a friend whos grown for years give me what he uses and up until i mixed the nutes wrong everything was fine, and seem fine now apart from a few bottom leafs, basiclly i have a 2 part veg, then 2 bottles of some kind of root development, i havnt got a clue what they are as my friend tears the labels off so i cant go out a steal his formula, (weirdo) like it matters haha basiclly what i did was instead of mixing 10mls of veg to every 10 litres i only mixed 1ml as i thought that was the root development, so then chucked in 10mls of the root dev that was only meant to have a 1ml added, thats a big difference especially when theres 4 bottles of each, as you can imagine the next time i went in they didnt look well, burnt tips, so to me thats definitive proof that i affected them, my plants have all been topped and super cropped on certain ones as im growing in a small height area and since i fed them wrong i gave them water first feed then gradually up'd the dose back to normal, i know i cant be sure as its my first time but ive seen alot of grows and im not saying it isnt what you say it is, but me and my friend have exactly the same going on and his are totally fine, i wish i could show you some natural light pics, and the leafs have been like that for around 2 weeks now and it hasnt spread, tbh im actually quiet happy with them considering i nearlly killed them ha

What are you feeding them, how often, and what did you "burn" them with?

EDIT: and just curious, what's your growing medium.
I was feeding them vitalink veg a and b, and a part root development, and im in 100% coco, hence why ive been giving them nutes from day 1, ive always given them lowest recommnded dose, as it says to add 1 to 2 ml per litre but my understanding was you should only use up to 2ml per litre if you're vegging longer than 4 weeks,i havnt, my ph is around 5.5 to 6.5 i have no idea why it differs ? I gave them nute burn by giving them 10 ml of root dev instead of the recomended 1ml, and gave them 1ml of veg instead of the recomended 10ml, as i was mixing into 10 litres of water?

I don't know what's up with your plant but it looks like a lock out. You grow in coco so I have no idea, grandmah grows organic. Those leaves happen to me at times and what helps me is magnesium but we do grow differently and I'm sure there's some mag in your nutes. I wouldn't cut the leaves off though. Let the plant take what it needs from the leaves
