Lime green tops?

Is this pretty normal when flowering? Or are they outgrowing the nutrients? day 4 of flower

From my experience that is from rapid new growth. As long as everything is on point your doing lovely.

awesome! They look healthy, just the lime green tops. Been using FFOF with earth worm castings and dolomite lime. So far nothing other than seaweed extract for food. I Was gonna try to run them out without feeding anything other than seaweed. Was hoping that wasn't causing the lime tops. But I'll play it out!
