need advice! life or death :(

nah because thats why I'm asking, i don't wanna pull the dead one yet just incase the buds can still grow cause there still green just all the leaves have died off but still small buds cause its week 2, I'm growing in coco, ph'd at 5.7-5.8 in a ppk grow but instead of a main res they are there own res underneath. 5 gallon pots. buds and sugar leaves aren't burnt/affected apart from pistols turned brown/amber already, I'm trying to get pics but its not uploading on here... think ill chuck it and stick with the 2 plants and start some GSC autos in the process

oh okay, do you know where? i thought this was the place to put it up haha? 

I had a problem wiyh an outdoor hydro plant near in ground plants. It got stressed out and turned hermie and polinated my other girls. Just saying be careful.
