i have watering my day1 with local veg's stag...

Your feeding it enough for the time being , if you feed it to much more then what you are now at this stage it will burn and die . I would start your system up because your plants going to need water or it won't live . Your solution temps should always be 20 to a max of 23 this will ensure your solution stays at optimal temps for your plant . The RH of your room should be 60% or above at this stage , in this stage you wanna emulate a green house effect lowering the humidity little bits at a time over a period of time till shes a bit older then you can average 50% . As for the air temps in your grow room , you wanna keep them between 23-26 during the day and 19-21 during the night . Later on in flowering your going to want them abit lower but not by much . So over all your on the right track , just pay attention because hydroponic systems aren't forgiving if you make a mistake that could be the last mistake you make type deal . I hope this information is useful to you on your journey to becoming a Grow Master !! Happy Growing!
