Its week number 2 so I'm changing my water out and adding new nutrients also. Probably gonna up the micro and gro just a little bit. Sent from my SM-G965U using Grasscity Forum mobile app
Won't hurt to change, but when small the nutes don't build up salts as bad as when they are flowering. main thing is keep a close watch on PH and keep the PPM's down for a little while.
