Ok this is what it is I have a white rhino in my box 9wks old under 200 watt cfl in fox soil with fox trio. I checked the ph seems to be good 6.5. Next wk I'm adding Gravity to the nutes and I know it can be harsh on her so I need to figure this out. The leaves (just the tips) are curling add turning brown. No other burning on her. Can under watering cause this? I give her 200ml every other day. Please help my first grow and I don't want to fuck her up.
