I have a 5 gallon hydro kit with a 2 week old white rhino growing in there right now. Everything was fine except when i checked on them yesterday some of the bigger leaves were curling up from the sides (not brown or dry) curling inwards. The ph lvl is around 5.8 - 6.2 and its being feed with dyna grow. I have a 110 watt flouro as the light source. So if anyone can help it would be really appreciated ty.
