oohhhhhhhhh.....i <3 mh...

i am sorry, i cant say much about your lighting, i dont know how much space you have or how many plants....

i would just keep feeding every other day.....check your ph and adjust to what it needs continually, it can change from meal to meal for the plants...why would you water inbetween? every other day should be sufficient i would think..esp with your temps.........but that is just me, and how i grow.....everyone does it different, and you will find over time what works best for you...i hope this has helped some....good luck....
