Nutrient or light burn?

[Gjourney101]

Hey guys, so.... I originally thought this was a nutrient burn problem. I haven't fed any nutrients in a week. And I still see symptoms. Now I'm thinking it's light burn and if it is I'm f***** because I cant raise that light anymore. Only thing I can do if that's the case is remove it from the tent and rig up the light somehow. Anyways, I posted 3 pictures. 2 of what the affected leaves look like, and one of what the bottom half looka like(pretty normal). I notice these symptoms near the top of the plant, some just a bit below the canopy. Is this serious nutrient burn or serious light burn?

I mean, as a last LAST resort, I can cut a hole in the bottom of the tent the size of the pots diameter and raise the entire tent, leaving the pot on the floor which would in turn give me 2 more feet of light room. Hear me out, it sounds tacky, but it could work nothing else.

Shiny dark green leaves is nitrogen toxicity this is a common problem with Miracle Grow.

Anything I can do about this? I can't switch mediums, but is there a remedy? I've stopped all applications of nitrogen as of 2 weeks ago. I stopped my bloom nuts last week too. A large majority of the plant isn't affected, but on the leaves that are you can definitely notice it.

Don't stop bloom nutrient,
There is two thing to do in this situation
1) just water with PK till harvest.
2) flush about 5 time you pot capacity with plan pHed water then feed liquid nutrients, you may still need to exclude the nitrogen.
Miracle-Gro is the wrong choice for cannabis indoors, I know Growers that use their nutrients line outdoors and do great, but indoors almost always end bad. Next time use root Organics, foxfarm or kind soil.

If they're that small and you're already out of vertical space... that's a problem.
