Yellow leaves

Looks like she is in late stage of flowering witch if that is the case that yellowing means you did something right she is using stored energy to ripen her flowers Flush Flush Flus!!

Feed them! Cut some of them inner leafs.. the big yellow one‘s, humidity down on 50-55% max in Mid Veg on 19grad celcius

Give more feed, monitor your EC/PPM and PH of solutions going into the medium and coming out. This will let you know hungry it is. Good Luck

That's obvious lack of them. Your girl should be in theory a lot greener still. Why lockout happening without diary, or is just lack of nutes - hard to tell. You still will push her and it will be weed to smoke, just at least double less, than could be ... Many options why it happened ... I bump into something every second grow and generally I don't do mistakes, bit shit still happens from time to time. It's fun to smoke your own, but a bit stressful while you go there ... Good Luck !

I'm guessing she is hungry. Also you should lower humidity in flower, you could end up with mold. Also you should clean up dead and decaying leaves as they will also cause mold.

She look hongry to me 😁
