Deficiency ID help

Its a little hard to see, but if you look at the leaf edges in the close up pic, you'll see that it's starting to fade and develop a reddish/brownish color. The other pic is just so you know what the whole plant looks like. Ive been trying to ID it myself using different deficiency keys, but I'd love to hear what other people have to say. Any feedback on what deficiency this might be and how to fix it would be appreciated!

p.s.
The plant is flowering and growing in subcools super soil under a 600watt hps. I just feed it water, besides an aerated compost tea I feed it every couple weeks.

Can see much under that HPS, but fuck supersoil, yea I said it...but you prolly just need to feed the plant...

Need better pics and more details ie is it happening from top to bottom.

fuck bublon , i aint never heard someone say fuck SS?
dirt is harder to grow in despite what the world thinks.

that girl needs some N bad. but it seems only one is having that prob? if your whole room looked like that , i would say to give it some N right now. (non-organic) yea who cares what the other one looks like , you dont have time for all that. just give the worst one a heavy dose of N an see where your at in a week.

no , no. i didnt even know there was a name brand "supersoil" ?

he is using Subcool's supersoil. subcool is a renoun soil man! its just a recipe to make your own. (with the ingredients he likes to use) its a VERY good soil that most people can water from start to finish with no food at all....only water.



sorry for the confusion.

I'm not 100% sure but the closest one i can find is the start of calcium deficiency.

this is horrible info. why would you even suggest nute "burn"?

read and look at pics before suggesting shit. the guy suggesting calcium of some sort at least tried.

the main plant in the pic looks fine. the one on the right needs N. thats all. it could be something locking the N out, but that is the only other choice.
