Healthy but unhappy. Digital timer suggestions?

Unreleased strain and these plants are very healthy but I can't keep them happy. First time growing these. Eleven days since flip and I've been unable to keep these plants happy for pretty much the entire grow so far. Ebb and flow on a mechanical timer. One watering per day is not enough and it seems twice a day is too much. Might a digital timer with a bit more precise watering help? I've not found digital timers to be very reliable but at this point I'm willing to try another one. Any suggestions?

Heres my droopy grow. I'm almost certain from too much water. Ha.
