Newbie here: I have some cabobmba which I believe is purple c. (it was a dark army green with purplish leaves near the top). At first it grew nicely but now the bottom leaves are turning yellow-brown and falling off. Some of the top leaves are still pearling with the bottom leaves falling off.
The cabomba is in the back but not too close together. what gives?
i have a 29 g. 2x65w CF 6700's . DIY CO2 - 1 bubble every 1.5 seconds...Using flourish at triple dose with salt subst. for K until GW ferts arrive.
