Firstly apart from the yellow leafs you plants look good
You're nutes could of changed you soil PH level just check that also it doesn't look like nute burn but could be some sort of nute deficiency you can have a look at the threads that address this
it will give you detailed info on each nute deficency and you could be able to see which one since it has so many pics.....sorry I can't remember the name of the thread

The bottom leaves are farthest from the light source and therefore may not be effective enough for the plant to keep them around. Yellowing is natural, especially of the lower leaves and especially during flower.

Don't trim the leaves. The plant will cannibalize any material it deems ineffective, so just let it suck the nutrients from the leaf and remove when it only requires a slight tug. If you gently tug and the leaf doesn't come off, LEAVE IT.

It could be a pH issue you've created with the nutrients. Do you measure the pH of your nutrient solution before you administer it? Or do you ever take a pH reading of the water you use? This is an important variable to at least be aware of, especially if you plan on using that Tiger Bloom, as it significantly lowers pH.

Don't cut leave until 60-70 percent of leaf is dry or covered if you do it will just go to another leaf. Flush for a week no nuts then get back on them. How many teaspoons per gallon hav you been using? Are you useing grow and big bloom at the same time? Your leaves are alittle dark so I woul deft lay off the grow nut. To much nitrogen will turn your leaves dark and the browning and yellowish will go away with flushing.
