Normally when the yellowing starts on the lower leafs its a nutrient deficiency with most times being nitrogen. Have you been feeding plants? If not its probably time to replenish nutes for her

Hi @3irdylover ,
also a warm wellcome from me, and like @Smokey101 said: „feel free to ask“, there‘s allways an open ear in our community 
When looking at your pictures I noticed,
Some leaf tips have already dried out and are curling downwards, which could indicate nutrient burn.
At first glance, this looks just like nitrogen deficiency
but the cause is that the root tips are burned by over-fertilization, which then no longer allow any further nitrogen uptake.
Often, damage symptoms appear during growth that look similar but have completely different causes.
That’s why we ask about the parameters of your setup.
Fertilization behavior, temperatures, pH value and light intensity are probably the most important factors we need for making a good diagnosis.
Good luck

What strain? What soil of grow medium are you using? What nutrients are you using? What kind of light and par/ppfd are you giving the plants(app called photone can get these measurements) Lastly are you running a photoperiod or an auto?
