I'm not trying to scare you off feeding but the tendency is to always over do it.
I don't think you should bring any outside stuff inside. The most recent issue of Urban Grower or some shit has a horror story about killing a grow by bringing in outside plants. If you must though, quarantine it away from everything else til you know it's safe.
Yea man this is what worries me, the thing is:
1) The plant is going to be giant I suspect, its only may 15th and the thing is nearing 2ft in height with a very thick stem. NOT good because I suspect it will be spotted, its low traffic area but there is an area where rarely some people will walk only about 15ft from it althou it should be blocked from view by foilage, but if this thing is 9ft tall it is going to be spotted likely. I thought it was an indicia but its quite obviously sativa dom
2) Its right next to a waterfall on the shore so I am afraid it might get washed away in high tide (its buddy 2ft from it, already got washed away after we suffered about a week of heavy rain)
3) It is likely to get eaten by an animal like many of its brothers/sisters, its the last survivor of about 20 plants.
4) It is likely to become infested with insects or maybe mold.
5) like I said its the survior of 20 plants.
So yeah I am highly considering not taking it in due to yours and others advice, I am likely going to just move it to another outdoor spot that can be watched easier and put a tomato cage and stuff around it but bringing it indoors is definitly up for consideration also.
It is not in a good place that I can go to very often so I can check it once every two weeks tops - really hard to care for.
another factor that makes me consider NOT bringing it indoors is we have a lot of people giving/selling us clones soon so we are rapidly coming close to our plant maximum already (our legal maximum is 48 right now, soon to be 60)
