Sorry… On my way out… But I would suggest strongly checking the DLI thread @Nicky started it may solve your issue. The Photon app and lux app he has a chart and all instructions. Getting the light and water correct are important. What’s the temp in the tent? Exhaust hooked up yet? Heat and humidity are also important. Will get into that a bit later upon my return home.
Also what are you currently using to water with… Are you pHing it to about 6.5?
Don’t over water… Just spray until you start to see extra leaves forming.
