Picture one is general appearance of almost all the leafs reddish veins and yellow green appearance and pic number two I’m not sure if it’s a deficiency or from what I have researched “rust fungus “ but it has not spread to any other leafsmainly loosing their green hue and getting more yellow
Without knowing further environment conditions and growing conditions I’d guess sulfur deficiency or phosphorus excess. The small amount of rust could be a calcium deficiency but it looks minimal. Good luck!
You'll be ok. I underfed a bit in organic and have some similar leaves at about week 5 flower. Not too worried honestly. Just more of a reason to learn from the mistake and be on top of feeding properly. Worst thing you can do right now is go crazy and mess them up.
