Does my plant have root bound or root rot

[purearien]

title says the gist of it Im thinking if it has pythuim or if it’s root bound or smth else entirely a few weeks ago I was inspecting my plant when by the touch a leaf fell so I touched more an more leaves fell so I ran my hand across the plant an around like 15 leaves fell easy by the touch some leaves were yellow an some leaves were completely fine then daily like around 5 leaves fell that’s a rough estimate i was thinking maybe it’s pythuim becuase I smelled the bottom of the pot an it smelled fishy so I took the plant out and soaked the roots in a hydrogen peroxide mix then I transplanted it into a new pot with new soil but I don’t think it worked it’s still loosing leaves every other watering I water it a hydrogen peroxide mix idk if it’s doing anything something I noticed tho was the leaves were only falling in middle of the plant some leaves also fell from the bottom but the top of the plant looks completely fine an healthy no leaves are falling from the top it’s been a few weeks since the treatment pretty much all the big fan leaves from the middle are gone only the tiny fan leaves that are directly connected to the tops and bud sites are still remaining but some of those leaves are wilting and turning black and I noticed in only a few of those leaves Some parts are turning white I’m starting to think maybe this is root bound because when I transplanted the plant, I was looking at the root system and it colonized nearly the entire pot completely circled the entire thing but something I’ve been noticing was throughout all those weeks of the suspected root rot and the treatment The plant never stopped growing it actually is growing pretty fast it was only a few days after I transplanted it slowed down only a little bit for a few days the main reason why I think it might have pythium because a few days before I lost those 15 leaves I watered the plant a lot and I left for a few hours when I came back the runoff made a big puddle and submerged an inch or half an inch of the pot and water



I only use a t-600 mars hydro led light an general hydroponics flora feed the strain is Kandy kush I’m growing it in my root outside my tent as I’m growing it as big as I can till the natural light schedule changes to 12/12 I’ve been growing it sense November






Don’t mind the trap house background

Has that plant been reveged? It looks like it was taken to the brink of flowering at least once and then bounced back. There's leaf morphology, ie loss of serration suggesting an irregular light schedule, and the toasted calyxes and what looks like failed bud initiation lower on the plant... Overall plant volume is not congruent with the size of the pot. It may not be bound but it's growth-constricted. Small mistakes become amplified by magnitudes.

I agree surely looks like it flowered and i don't like the colors of the branches at all. That old yellowing color like it's dying. I'd say a combo of not enough light and too small a pot with little to no soil for the roots. It cannibilized itself, ate all the nutrients it had stored.

I just reread your original post and if I read correctly this plant has been on natural light since November and honestly, it explains a lot of what we are seeing. Just know that on the shorter half of the Equinoxes (September thru March), plants need supplemental light to remain in veg, and in many parts of North America you need supplemental lighting all year except mid May to mid July.
