This all related to nitrogen toxicity?

Ok, so the background info

2 plants, 3 gal fabric pots (FFHF & FFOF mixture), 3x3x6 tent with 1 SF1000
Plants are appx 7-8 weeks from seed, have only given water, they’ve had 2 full feedings since transplanted in middle of December, last watering was 12/28 with 3/4 gal per plant.
Day time temp/Rh: 79~83 75~81%
night time: 73~76 73~75%
Light was at 100% appx 12” above, have since moved light to 18” above and 80% power

So I’m pretty sure I’ve got some nitrogen toxicity happening from the soil-at first just some claws and one or two crunchy spots. Today I’ve noticed more crunchy spots, twisted edges, and a random pinhole. Just want to get a wider consensus and see if this is all related to nitrogen toxicity and if there’s anything I can do to help the issue as it is.
Pics 1-4 are from 2 days ago when I first noticed the issue 5-10 are from today.

You need more light by my observation
Yeah I agree with you completely. Trying to save my pennies to get an SF2000. I managed to pull a few ounces off 2 plants with this setup last cycle so will hold me over until I can get better gear.
Do you think this issue is more light related or potential nitrogen toxicity?

I would focus on just one plant if you do another run

and yes
