well as "Stinkyattic" mentioned, it's most likely that the plant(s) need sulfur and good way to tell is if the "Purple Steams" are inside the leaf..... Other than that they're healthy as long as you have no other Def Probs....

And yup your doin better if they turned back into Green and started growing again...But hey its always good to be safe and i don't blame you for making a thread about...Keep up the good grow man...
