The second shot from above you can see my biggest one on the back right got burnt a little from the light but doesnt seem to have effected her growth
and you should be good... 
Hi mate,your plants look ok in the pics.i think i can see the burn and a bit of yellow on the back plant but other than that :thumbs: I'm not familiar with the fox farm nutes but someone will jump in and help you on that one bud :group:
yeah man... I'd start the flower nutes a bit... and maybe a 1/2 dose of GB still too stretch em up a bit as they flip into flower..
a lil cal mag prob wouldnt hurt em either... just keep your phand you should be good...
and if you have the big bloom... def be generous with that... not crazy... but use the heavy feed sched.
tiger bloom... be careful it swings ph low fast...
