sick purple urkle

this is my first grow. These are my purple urkle. they are now 4 1/2 weeks into flower or day 33 of flower. so i decided during my first grow that i needed to go on vacation to see my mom that i havent seen in 20 yrs. i have a guy i work with that "supposedly" grows. i figure he could babysit for a week. i left on the 22nd of may got back the 28th. here is a video of the girls berore i left on vaca and the pics now. sad sad days. i am going to do my best to try to figure out what is wrong with them and bring them back i dont know what i am doing though so wish me luck!!
