That 70's Grow

Having a problem with droopy leaves on my largest plant.... the roots are growing out the bottom so I think it may be time to transplant but I'm afraid to move it until I can address the leaf drooping. Any suggestions or ideas would be greatly appreciated. Per the replies I received I transplanted "droopy plant" this morning before the lights went out. Mixed 3 parts "Purple Cow Indigana", Coco 1 part, Worm Castings 1 part mixed in Beanstalk K-Boost and Absolute Flower and also fed it with Recharge. I am waiting for Beanstalk Fortify and White Shark which should be here tomorrow, and I will sub dress then. I put it in a 2 gallon cloth pot, I have 7 gal pots coming on Monday but did not want to wait to get this into a larger environment. I appreciate the comments and help. I am also still waiting on Delta Leaf to tell me the sex of my plants. I would feel silly going through all of this and the worry involved with my babies if it ends up to be a male. I don't know how to tell at this age so I mailed the kits in 10 days ago... F_ck the USPO. The other large Stoopid Fruits started to droop a bit so I put it into a 7 gal cloth bag... Delta Leaf received all 10 samples and I should hear the genders this week. If they were all female I would transplant them all tonight. Well, the "droopy Stoopid Fruits" is thriving after the transplant. I won't get the genders until Tuesday so I transplanted all the Lemon Haze and 1 Collie Man Kush. The Stoopid Fruits is in the far left of the new picture and shown by itself. Was told to use CalMag but I had already clipped leaf.
