Right off the get go I'm gonna say it's not your watering times it's your PH. Also did you soak RW in PH'd water?? How often are you watering them now?? How old are they?? Are they on nutes and if so at what mixture and type, also list additives if any kk?? What is the PH of your water that you give the plants and if it is adjusted what was starting PH and where water from (tap, rain, neighbors pool, etc)?? That is just a min for water.
Chapter 2:
Lights-
What kind and what wattage are your lights?? Time on and time off?? Distance form top of plants?? Are they air cooled?? What is temp range in grow area (lights on/off)?? Is air circulated inside grow area?? Is the area vented??

One thing I have learned so far in this wonderful exp of growing your own is nobody has a magic wand to wave at the other end of your internet connection
If you are unable to give up this info then I (and most others who dont guess) wont be able to help with your problem. Lastly if you have no clue about the things I just asked you will have better luck dropping a seed at the window into the backyard and crossing your fingers. :wtf: By no way shape or form am I trying to be mean or cruel just talking straight forward and honest :jointsmile:
