About to bin my 3 month old plant!

Pictures under normal light would be helpful.

I would of just took her out the pot, washed the roots off and potted back into all coco or all soil, coco would of been my first choice though.
Then chopped her back and splayed her out a bit. No need to start from scratch, she would come back good as long as there are no serious bugs involved.
Personally I think the medium is the problem.

P.S what with all the ducting?
Is the fan on the floor intake or extraction?

Sorry dude, posted so much about this damn plant I couldn’t even be arsed! The PH is usually around 6, though run off always around 6.2 as there is magnesium limestone in the coco. Pic shows the water with an abundance of calcium, and stopped because the damn thing seemed to have been clogged up with calcium from the tap, so wanted to give it a week of no nutes. And also there is some nutes already in the medium, so it’s not getting nothing.
It was burning left right and centre. Hooking, yellowing, wanted to try to clear out the root zone then go back to nutes.

As you can see there is all sorts in the tap water

for coco you want 6.3 ph. ignore your run off ph, you can't control it, and this isn't hydro (no matter what people say about coco, it's a hybred with its own characteristics, and if you treat it purely as you would hydro, you'll have trouble).
dolomite lime is good, but it takes time to break down, use a little regular garden lime with it and it will break down quicker, covering the need till the dolomite starts to break down.
just quit using your tap water, 450 is too much when you have no control over what it is. get an ro system, or just buy the big jugs if you're only growing a few plants at a time.
flush it out good, reset your medium, then immediately water it with ro water with 1/4 strength nutes. over the course of 2 weeks or so work it up to what seems like a reasonable level. if it doesn't like it, back off a little.

or...trash it, and start over....depends on how stubborn you are, i hate to give up....

I can still do this? I mean, I thought about it but wondered how the roots would feel, and how I’d even bed them back in to a new medium! Just plonk them in? I’d happily do this to be honest, if it would help. I’ve tried flushing but hasn’t seemed to have helped.

And the ducting lol it’s my exhaust fan, though my tent is small, and having the fan at the top stopped me being able to move my light up any further, so I dropped it to the floor, but haven’t connected the ducking to the carbon filter yet as no smell. So yea just an exhaust fan!

To be honest, I didn’t know if it could bounce back, and now knowing that it can, I won’t trash it, just so frustrating! I’m really considering just re potting it now, as I’m sure my medium has issues that I can’t get rid of!!

Its dry right now and due a feed, so considering getting a new medi, or maybe just reporting it in the same medium, but without the tap water?

 

[Tuckatan]

In th 10 minutes since my last post I decided to go for reporting in the same medium, as I have everything to hand. I’ll give it a couple weeks and get another medium ordered in the meantime.

Current medium is real dry and light but still moist enough to stick around the roots. My total noob questions are:

How do I get the damn thing out the pot? I’ve squeezed edges etc to try loosen it up. Should I continue until I can pull it out?

Do I take to the shower and rinse off all of the old medium?

Do I just make a big enough hold and plonk it down in the hole then cover with medium?

Thanks for your help guys, you’ve given me hope that the plant can be salvaged so no time constraints, just Gona keep her going until she recovers !

Should I start with quarter strength mutes and see where I’m at?

 

[Roger A. Shrubber]

i just squeeze the pot good a few times, then turn it over and support the base of the plant. if it doesn't just slide out, a good slap on the bottom of the pot usually breaks them free.
if you've already flushed that pot, i wouldn't worry too much about getting the roots clean. i just put a couple of inches of medium in the bottom of my new pot, set the root ball on that, and fill in from the top, shaking it often to get the medium to fill in the gap between the old root ball and the side of the new pot.
and yes, start with 1/4 strength, and work up from there...with ro or spring water

Thanks bud, that was more difficult than I expected! And I’m an idiot, my pots fabric so I just cut it open! Still, that was a ball ache trying to get the dirt out! Got a good amount of it out, and reset it into the new pot. What I did notice, my medium has gone from holding 6 litres plus, to giving me run off at 2.5l. Is that because the medium hasn’t filled in the gaps?

probably.
you don't even have to cut most fabric pots, you can just bury them whole and the roots will grow through the sides into the new pot. i've had them root themselves to the ground in a day when i sat them outside

Yeah you can still do it, its only a plant. I wouldn't of put it back in the same medium though, seems to me the medium is partly the problem, it contains various amounts of this and that and you don't know how much or how long it will last and then when you run out of X you add some nutrients and have too much Y and Z.. That leads to too much of one thing and not enough of another.

You could if you have room above the tent just sit the fan on the roof outside the tent and have a foot or two of duct poking through.

How close is your light to your plant? Seems pretty close to me they may just have burned out from the heat

Start treating the plant like your child and not some mechanical moneytree. i thought i had problems sheesh that is a sad sad plant, put it out of its misery, brought a tear to my eye

 

[Tuckatan]

Afternoon guys! Or morning, geographically dependent.

So, since we last spoke, I repotted the plant into the same medium. I’ve re checked the medium ingredients, which is this - https://www.growell.co.uk/growing-media/soil/tropic-bat-mix.html

My plant, since repotting (I may have been a bit rough with the roots) took around 2 weeks to start to grow, and in this time looked like a bunch of twigs with zero leaves. Now half the plant is turning green, with the other side slowly greening up. Problem is, I’m now again getting brown blotches on my leaves again, which then dry out. The problem hasn’t gone anywhere lol.

I can’t work out how to remedy. It looks like phosphorous deficiency but there is a load of guano in the mix. Fed first 2 feeds with half strength nutes. 3rd feed is plain rain water, at the same time I discovered the brown splotches reappearing on the leaves.
A lot of the small fan leave ainstantly turn yellow and brown up, lower leaves especially.

I’ll add pics to the post at lights on. An hour from now.

I’m looking for a new medium, I’m going to stick with coco/peat... does anybody have any reccomendations?

Also, when looking st Pom ranges for plants in different stages. 900ppm for veg etc... this is the run off right? Because my nutrs deionised comes in at around 50ppm! That’s a question I’ve had for a while, as I can’t fathom getting my water up to 900ppm before feeding!

Anyway, if anyone has any good medium recommendations, available in the uk, I’d love to hear from you!

Pics to follow.

And for the record, ph water in at around 5.7 lately, as previously was PHing to 6.3ish before feed, so thought I’d try lowering the ph thinking it might increase phosphorous uptake. Leaves still suffering. Found the first affected leaves 2 days ago, after reporting in fresh medium on 19th November. Half the plant still looking almost dead though.

Pics to follow!

Thanks for your input. I’m not growing to sell, it’s in no way a mechanical money tree.

It’s almost embarrassing showing the pics!

I must reiterate, I’m not too concerned with yield, (which is lucky looking at my poor plant!) I just want to try to work out what the problem is, and gain some knowledge for my next grow.

Damn man must be one of the worst looking plant ive seen in quite some time not too sure how you ended up getting to this point.. have you tested your ph? Your soil is maybe not in a good range creating locking of nuts.. there is probably better way to test it but water your plan when its dry and let some runnoff try to capture the runoff and ph test i (dont allow too much runnoff because it will dilude your result.. it may not be 100% accurate but you should be able to quickly identify if its coming out at 8 ph or 5 ph and maybe guide you into a resolution.. your ph should be more like 6-7 rather than 5.3 in soil your soil may be too acidic.. if you have that at home try baked soda mix with your water for one feeding should increase ph of your soil for quite some time and its no harm to your plant..

Also not sure what you mean about 50ppm.. thats usually your normal water ppm.. when you add nutes it doesnt get higher than 50? Something is off.. the stems are very red as well so really seems like something is going wrong in the soil

Edit : I wouldnt even harvest that plant however you may want to try take couple branches and clone it and start over

 

[Keeprollinup]

I use coco with perlite feed coco A-B and big bud and that's it never had a problem tbh. Is this plant still in veg?

 

[Tuckatan]

To be honest, I’m not looking to harvest, just hoping to find where I went wrong.

I grow in coco/peat, and I usually PH water/feed to 5.8.

I started feeding the first couple months with tap water, but my tap is 450 ppm with huge amounts of calcium. Started seeing what looks like phosphorous deficiency, so figured maybe the calcium locked out the phosphorous. Started with deionised with a starting ppm of 002, increased to 50 with nutes. Run off is around 900 with a ph of 6.3. My medium has bat guano, magnesium limestone, calcium already included also.

It was showing real bad, what looked like phosphorous deficiency, and all leaves went brown blotched, to crispy, with some top leaves showing some red/purple hues. The stems were always purple when healthy, I think it’s genetic! Once it lost a load of fan leaves, I re potted in a new medium thinking there may have been calcium buildup still locking out P, took around 2 weeks to recover, and only one side started greening up. One side started to look healthy ish, other side started coming back, then the brown blotches started reappearing! I’m starting over with a new grow along side but still want to try work out the issue with this. Maybe I’ll just cut my losses, just wanted to take something away from this grow! At least a lesson in what I did wrong, but can’t seem to put my finger on it!

Thanks for your reply though bud!

Plant is still in veg, my initial thoughts were to fix before flowering, but the fix didn’t go according to plan! lol.

I’m using coco/peat. Is there a benefit to perlite? Im looking for pre mix really, im going to get some on order. I may clone, though would it turn out ok being such an unhealthy plant?
