Is this Plant going to die? Update...

Hi,

Posted a couple photos the other day but was advised to take more shots with the lights off so here they are... The plant looks finished! :( 70% of the bud sites on the thing have completely drooped down and died. Shall I Just cut these off?

And does anyone know what the problem is? My suspicion is that the food was just far too strong for her as she was half the size of the other plants but the other 3 plants are still thriving! is there more to it? or is this just a nutrient problem...

Should I even keep this plant? I will likely only get a few grams on her but I guess I have come this far...

What I find really interesting though is the flowers on her have actually matured faster but killed off the other branches in the process.... they are only mid week 4 of flower but shes already changing colours...?

Whats the best thing to do here? Thanks for your advice and help. And any ideas of a rough estimate on yield for the full thing? The other 3 seem to be doing just fine...

I think you should cut only the branches that droped and see how things evolve in the next few days
If you see others droping just harvest what is left

had similar problem on my last grow, the stems were falling down, problem was cold temperature, i tried to tape them so that they face upwards, it worked for the beginning, but later i removed 3 main stems which were affected, plant finished 1-2 weeks later than expected, had really strong nugs, but tastes was bad. good luck my friend

Yeah I don't believe it is temperature in this case though but I appreciate the input :) My temps hover around 24 C and 40-50% ish humidity. I really believe its the food but I could be wrong... The others have no issues though. seem healthy and strong and are continuing as expected. The branches that have drooped are a lost cause though now? I should just bin them? :( lol

Are you overwatering and drowning the plant?

You know I thought this might be the problem before... As I was watering a lot but its coco coir they can usually handle an every day watering... but my first instinct after i saw the droop was to flush the plant and then just leave it to completely dry out... but the plant continued to droop even so :( and all the other plants seem fine on the same watering schedule so I'm more in line of thinking its something to do with nutrient burn? But I am not sure, its a constant learning process. it sucks anyway :( I hope i still get a few ounce overall but I guess we will see how the next few weeks go lol

What are you pH-ing your water and water/nutrient mixture to?

The PH stays around 6.8 or so. but its been running through the entire grow just fine and this problem only started a week ago... it just started happening after week 3 in flower when the nutrient solution was boosted. The other plants responded fine but after about 3-4 days the drooping started and got worse ever since... So it's gotta be the food right?

Well, right off the bat, 6.8 is too high a pH for coco. It should be 6.5 at the very top end. 6.0 is right in the middle. Feeding plants at too high/low of a pH for the medium they're in can cause severe issues over time (locks out critical nutrients from being uptaken). The issues caused by out-of-range pH can be difficult to troubleshoot, because it's a crap shoot of what symptoms will actually show up.

I'd flush the medium with 6.0 pH'd plain water, then feed with ~1/2 dose nutrient mixture, again pH'd to 6.0. Carry on with a normal feed schedule, upping the dosage from 1/2 slowly if needed.

Alright man, That sounds like good advice. I will give that a go but I am still not sure if the PH is the root cause as the others seem fine..? Even so I guess it won't hurt. Should I strip the ones that are already drooped? They are a lost cause now right?

Don't cull the bad ones yet. See how they react to the proper pH. The goal here is to see if new growth grows normally or not. Trash it later if you want.

pH problems might not show up with all the plants at the same time. All I know for 100% fact is that your pH is too high, and that can and will lead to issues. If you've got other problems beyond that, you'll find that out, but a baseline pH is critical to figuring out any other issues.

Low/high pH has a tendency to show up as all number of different issues. Many growers just throw more nutrients at the problem, and that has the exact opposite effect that's desired. Now, not only is the pH off, but you've now given too many of some nutrients which act antagonistically to other nutrients, meaning you'll have deficiency of some because of toxicity of others (for example, too much N is antagonistic to K and Ca, and they can't be uptaken, causing an artificial deficiency). That's a bitch to troubleshoot if you don't consider pH or over watering as the potential cause.

Fair enough. I'll give a flush later although the drooping has kind of subsided I feel like the worse is over but it was just like 5 days of toxicity but I do believe it was the nutrients even though I was just following box recommended dosages but the plant was always a little behind, i remember having to give it a weaker solution in the vegetative stage as well because it got slight nitrogen burn on the same dosages as the other plants... I'll dial back the nutes after a PH reset flush and see how the next week progresses. Thank you anyway :) I'll post an update as time goes on..

google fusarium wilt or root rot and compare the symptoms with your plants.

THATS IT!

"So what causes root rot? If you’re growing in soil or coco coir, there’s one main cause: stagnant water at the roots. If your plants are sitting in old water that’s getting light (from the sun or otherwise), their roots are connected to a breeding ground for unwelcome organisms."

That's exactly what it is dude! the plants have been sitting in old water thats been in contact with the light getting algae in the water and all sorts!

Thank you man! That is the exact source of the problem! Now i can fix it going forward!
