Couple things went wrong and resulted in slow growth and stunted plants. Flowers were VERY slow to develop. Started researching and finding more and more wrong with the setup.
1. Water was not changed frequently enough (every 6 weeks)
2. EC was far too high - result of not changing water but topping off nutrients every week
3. Water was too hot - AC failed, no chiller
4. Plants outgrew space and pressed against the light
5. Not dark at night - no grow tent (bought one when I realized)
