Nute burn or deficiency?

Can any of you identify a specific type of burn on the tips of my leaves? I can't figure out whether it's just normal nute burn or if I have a deficiency that I can't pinpoint. I've had nute burn on other plants and it didn't look quite like this. This starts of with a bright yellow color then a really specific brown color after awhile. The necrosis itself is not on all of the leaves, yet most of them are severely clawed and have a very dry feeling to them, along with the yellow tips. Im also starting to notice some weird folding going on with some of the blades of the leaves. Im pretty sure I have too much nitrogen but is there something else im missing? Im in Miracle Grow soil but I would've thought most of the nutes would've been flushed out as I've been in it for around a month and a half, plus I made a 50/50 mix of MG soil and some cheap non fertilized soil so it's not full strength MG (or at least I thought). Just hit week 5 of flower. I only noticed this problem after I used a stronger dose of the organic flower nutes I have, rated at 1-3-1 along with 1% calcium. I flushed the soil the next day and this is how they've remained since then, around 6 days now. Any help would greatly be appreciated as this is my first grow and im still not very skilled in the way of identifying problems with the plant through the leaves and id hate for something to be going on currently and me not catch it and fuck up my yields

The tips curling like that make me think it's too much nitrogen

could be the start of n toxicity, tips look like it

That's what I was thinking as well. This plant has had a shit ton of issues all throughout veg and it suffered some serious pH issues which caused alot of deficiencies and toxicities and after that I don't think the plant was ever the same, so I guess it being in Miracle Grow soil, on top of the flower nutes im using which also has a bit of nitrogen in it, it's all too much for the plant to handle. I ordered some flower nutes that doesn't have any nitrogen but is higher in P and K so that way I can try to keep the N levels low. Im gonna only water it for the next few watering to see if that helps. My only worry is the time release nutes in the soil, it's said that every water releases more nutes so I guess maybe if I water a little heavier than I normally do it'll help flush the excess out? I just don't want to fuck up what I already have lol

I'd say the N claw is very minor. If you back off the N a little you should be fine.
