Need some help first time grower!!

Hey guys, I'm about 8 weeks into a Grand heft auto grow.. The leaves on my plants began showing deficiencies and I have no idea what the issue is.. I've broken it down to a phosperous or rust fungus.. Any help would be greatly appreciated! Thanks

Some pics of leaves

Got about 2 or 3 more weeks.. Really need to figure this out..

hello, you need to provide some information like soil, nutrients/feeding schedule, temperature/humidity etc and pictures of the whole plant + closeups of problem under white light.... otherwise I don't see anyone bothering with this.

exactly what davillains says, but guessing from looking at one leaf, you have N toxicity and they have locked out cal/mag, but before treating it for this id sure like a look at the whole plant and know what you have done. here is what a healthy plant looks like 8weeks into veg
This is her under her scrog net now been flowering for 6 days

OK here it goes..

Strain: grand heft auto
3x3 grow tent
2 Mars hydro led true 215w
4 inline fan and carbon filter
2 oscillating fans
5 gallon bucket
Fox farm soil
Fox farm trio nutrients

-The temp and humidity stays 73-78f and 45 -55% faithfully

-since I got my nutrients later than I planted the auto I've given it 1 feeding. It was qtr strength of suggested feeding and because the auto is already 8weeks old, I held back on feeding her again.

If you guys need any more info or pics, just let me know. Thank you guys very much and I appreciate you taking time and helping a fellow grower!

Some leaves became very brittle

wait for some others to chime in but looks like a cal/mag deficiency to me so you have given that auto no nutes? just whats in the fox farm soil?

truthfully that auto is almost done anyways and i wouldnt worry to much about it quick fix you could add a tbs of epsom salt to your next watering but id quic adding nutes if you are its almost done

I'd bet that bud is gonna taste like ass. I'd give her water only. I've been wrong before though.

Probably lol but let's hope it better than it looks.. I wasn't even sure I was going to smoke this anyways... But we'll see..
