if you ph is that high add some dolomite lime to the top of your buckets, this will drop you ph even more, I dont think Fox farm mixes theri products with to much lime other wise you would see it. I have seen people adding lime to theri bags of fox farm so I think this is your problem. However having never uses foxfarm soil, but I heat its good, I can not realy tell you about the soil.

But Lime sold at the same place you got the soil they sell it and usualy mix it for you they should have asked, if you buy just 2-4 pounds or so, even lesss you should be set, just put it on the top soil and hopefully you ph will go down. the problems are coming from nute lock out a ph of 7.5 and up is way to much I am suppriesd they are not hermied or dead, but it is a weed and will grow almost anywhere.
next time you know, add dolomite lime to your buckets before you add a plant, not the first time I have seen this.

one more thing for plants that small yo might wana try smaller buckets, it is realy easy to over water with a massive bucket like that, I usualy say bigger buckets but thats when your growing trees, for plants that size a 2 gallon pot should be enough,

rule is 1 gallon container for every month of veg.s then add a half or 3 quater to the flower.so for you a 2 gallon bucket should be more than enough. 3 gallon if you want to be safe, I see you have only half the buckets filled but smaller buckets will give you a smaller foot print int he room, means you can put more buckets.
