Nice, well keep an eye on her, but i think she's doing great. I just went through a similar thing. thought there might be something wrong but everything was fine. What strain? I'm currently doing northern lights X skunk #1. You should see them beef up at 6 weeks. wooo!

Hygrozyme is the shit. i love it. It's a little pricy but i think it allows the plants to be a little more tolerant of my abuse. haha. also i love the way it smells...is that weird?

The little guys in veg that look a little nute burned or deficient...
i'm not really good at diagnosing that stuff. What kind of feeding schedule are they on?

good luck.
