Branch connections weak

[Rootsruler]

One of the plants I have going has very weak branch connections. If I gently pull on a leaf or branch it will snap off. I've never encountered this before.

Anyone have an idea as to why this is happening?

Cultivar is a cross of White Widow and Sour Diesel. I have 4 plants total in Root Organic Original in 7 gal pots but only this one is doing it. It was healthy right before I gave it a dose of nutes that I think were too strong for it. I also think the mix was too hot temperature wise but I don't think this happening one time would do it.

The hot nutes probably locked-up the roots and now she’s starving for calcium. Give her a good flush to wash away any excess salts and add cal/mag to help her recover. Start with a slightly lower EC/ppm for a week or two, then increase the nutes gradually.

It's genetics. See below

I had exactly the same problem with exactly that strain from Franklin

I had to tape all its nodes.

Some completely broke off and I saved, others I couldn't.

Natural the manifold went to shit but its buds were the best...a1 dank as and knock you for 6

Please excuse the intruption Bluey but do you mean teflon tape like plummers use on threaded pipe, that is what it looks like? Never heard of that but if it works for you I will give it a try.

I currently have it under the ScrOG net but since it has its own light maybe I'll just let it go and, like you said, tape up all the joints to reinforce. I can always raise the light if it has to go vertical.

[Bluey]

Yes Allenpro. The tape plumbers use on threads. It works a treat.

When I get weak limbs I will super crop the in a few place so strengthen them, just make sure you have scotch tape and a support of some sort handy. I agree though some times it is genitics

Are these clones or the same strain grown from seed?
Does that setup water all of them from the same res?

Same strain grown from seed. That's what's weird. The others are nice and strong. No axial issues at all.

Yes. The plates are from FloraFlex. They also come with thin felt pads that help distribute water across the media. I didn't think the pads were really necessary but once I used them I saw how much they improved media saturation. If I'm home then I'll use a 5 gal bucket as the reservoir and mix up a fresh batch of feed for the plants on feed day. If I have to leave for an extended period of time, up to 6 weeks, then I use the larger 30 gal reservoir. I'm in the process of building a separate injection system for calcium products for when I leave for a long duration. If I'm feeding that same day then I can mix it all up without it precipitating but if I leave it any longer than that in the reservoir it'll start precipitating with the products containing phosphates and sulphates.

You can kind of see how I setup the feeder lines, two for each plate, to each site in this pic.


Distribution head. I'm going to reconfigure this a little differently by mounting the head to a 3/4" PVC pipe riser with a piece of 3/4" PVC spanning the tent floor and an air relief valve at the end. When the pump goes on I get pipe knock from the sudden rush of water pressure so a relief valve should stop that from happening.


Pump and reservoir setup. I'm using a pressure adjustable RV water pump. FloraFlex likes to see at least 35psi in the line for proper water dispersal.

[Bluey]

I used one of those balls valve float thingies once and flooded my room. I didn't have enough constant pressure to seal the thing properly

[Rootsruler]

I thought about that but because the pump has constant pressure I shouldn't have to worry about that.

Nice setup, anytime you can set up any kind of auto feed its worth it on my opinion, I had a few leaks in the RDWC after a few years so I dont think my wife would agree. I used the drippers on an DIY auto feed, it worked pretty well but I could never tell if they were clogged or not, the plant grow tells me they never werre. My problem is I get greedy for buds and end up with plants in corners I cant get to because Iam not as bendy as I once was. I am going to enjoy watching your grow. As for the runt with weak limbs it may surpriise you

[Allenpro]

What is the H looking support? Did you buy that as we see it or is it stoner creativity ?

[Bluey]

That pump you are using looks like it's the one for musting in an aeroponics setup....nice piece of kit

[Allenpro]

Its clever, was that Sativa or Indica stoner? I usually have them vertical and its always a pain in the ass doin it that way. Do you have any problems with it siphoning out of the res or is it vented?

[Rootsruler]

Allenpro Hydrid......LOL! With the current setup, when I start up the pump, it pushes whatever air is in the line out through the feeder lines but to prevent any airlocks an air relief valve will be installed.

Bluey Yes. I was surprised at how well built it is. I got it for $35 on Amazon. It also works really well for draining your water heater or to cycle cleaner through your on demand water heater.
