oh, you did some damage. what color are your roots? you had 3 plants in the same container? them being fused is exactly why it's ONE PLANT PER POT! even if they are all females they will fight over nutes and light. one or two will prosper and the other(s) will suffer. what if the good one is a male? hopefully it's lesson learned if this is the case.
i think 70F is the ideal(ish) temp for your res. like i said, i'm not a 'dro guy. i'm sure one of them will chime in.
i'm pretty sure 6.8 is a bit high for your pH. the ideal pH for soil is 6.3 (granted pH is strain dependent) and hydro is lower than this. how are you testing your pH?
