need help identifying problem. yellow leaves

hello. I need help in understanding my problem. my first grow was 5 males out of 5. so my friend gave me a female plant which was in a very small pot, 30 sentimeter tall, 2 month old, in bad shape, stressed and already flowering. it was in terrible shape so i decided not to top or do anything with it and assembled light around it on christmas tree shape. I reveged it with 24\0 light,replanted in bigger pot, it growed very rapidly but i got some weird looking leaves and some single leaves. which you will see in pictures. after three weeks it started developing yellow leaves at bottom and holes in some leaves, i see more and more yellow leaves. now i am in 10 days of flowering and need help in identifying problem. please help.

There fine. Maybe a slight nitrogen deficiency.. but hard to say because the yellowing seems to be contained to just those few sets of fan leaves. If I was you I'd snip off those dead ones so the plant doesn't waste anymore energy on them and can focus more on new growth. Good grow !

I'd test ph first, it seems to be the issue to most problems, if it's within range then you can start diagnosing

I meant "it seems to be the issue to most problems" in general not in your plant's case
