Grow #4: Milk and Qookies

I'm struggling with maintaining a regular humidity level The new light is working out great! The plants are growing at much different rates. If they were all as good as the best plant I'd be happier It's gonna be interesting to see how things finish! ___________________________________________________________________ So I made an attempt to save them/balance them. I fed them with just ph'd water to give them some time and incase they needed to chill a bit The runoff wasnt over 6.5 so I dont think they are locked up. I'll be back to feeding them again, but the difference in each plant has me concerned!
