Pic update:

I've been scratching my head over why the plants seem to be taking a shit on themselves...

beta: First one to show signs of the chupacabra. Only plant with overall light green color.

alpha: Unlike beta, this plant is not yellowing but has black tips... wtf?

theta: Looks like it will end up like beta if this continues...

eta: NO PROBLEMS, YAY! (watch this one be a male)

Temps are normal. Humidity is normal. No nutes have been fed, just plain ol' RO water.
