Need some help

[KingKongBuds]

Its clearly root rot .. sorry but at this stage its pretty much over .. ive done it before with miderate succes but it was earlier in the process .. peroxyde is good but its only in your res for a day max .. hydroguard on the other hand is there to stay so you wanna work with that
About the possible cause there is a lot of factor that can lead to that as the other mentionned but one other that i see is light leak even a tinny light leak can cause root rot
I heard a lot of people have great result with potasium silicate too but ive never tried it so maybe someone here with more experience can confirm hope it helped .. dont give up on hydro becaise of one bad shot mate

I figured it was a root problem from the beginning, if it really is root rot I don't think there's a way to come back from that?

And btw root rot can take a lot of shape almost every tocity sign can appear so make sure if your temp is ok in the res and enought oxygen. If its ok you may wanna block light to get in by putting something on top of it.
