Is this a sign of rootbound?

[GeorgeSmiley]

The leaves on a few of my bigger plants have clawed under big time. I have had the root aphid problem so I've been chocking up a lot of the little problems to the bugs and then the treatments for the bugs. But since this is the larger plants doing it and not the slightly younger ones that have had ALL the same treatments so I think this might be independent of any RA issues.



Not visible in these shots but I've had lower leaves turn yellow completely then fall off.
Thought I was having a feeding/ph problem but really, everything is fine PH #'s wise.

So the plants looks like this

Can really find no reason except I pulled it out today adn the roots looked like this

It looks rootbound but not overtly so........ I've never let cannabis root out like this before so just thought I'd ask about this connection.

If it were truly rootbound it should be using it's water faster than every 3 days correct?

Thanks for looking

How much of each nutrient are you using with how much water? normal feed rate 10ml grow/10mlroot/5ml calmag/10ml liquid kelp*Knowing the brand is very helpful*
How often are you feeding?Every watering until a single water only that directly proceeded this problem
If flowering, when did you switch over to using Bloom nutrients?
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)N/A

Has plant been recently pruned, cloned or pinched?constantly pinched, toped a week ago
Have any pest chemicals been used? If so what and when?Azamax, pyganic, BTi and diatemacious earth have all been used.
Are plant's infected with pest's?Had a root aphid problem but cannot find anything present.


Thanks a ton

it looks like a PH issue with the twisting of the leaves; is there any 'PH spotting' on the leaves? I think I see some on the 2nd pic on the leaves.
What is your PH before you give it to the girls?

Yeah George;

Watch those plants really take off once you get them in some fresh soil and let them stretch their legs a bit.

Classic rootbound IMO.

Thanks for the replies

I thought I had a PH issue but it did not make sense. Here it is

General organics says not to PH their nutes. I'm in soiless btw But their nutes drop to 4.9 when you mix and I didn't like how they looked so I starting feeding at 6.5 and they loved it, fantastic growth.

City changes water source my tap goes from 7.1 to 6.7. This problem pops up after I give them fresh water for the first time. I thought nitrogen excess but several people told me it was PH and I need to drop it a lot. Next feeding was at 6.3 then at 5.9 and now it still looks the same. I also put a layer of dolomite lime on the surface and watered it in on the 6.3 watering.

Yeah George;

Classic rootbound IMO.

Since this is not a flower out in the garden, should I break up the rootball at all? I never disturb cannabis roots when I transplant but I've never had roots like this.

I would try to unravel a few of the outer roots (with the help of a spray bottle for moisture) but "breaking it up" will result in huge root damage.

Definitely needs more soil nowish.

 

[orpanic]

the leaves are droopy like that because of the root-bound issue. Seems you fixed that by transplanting, just watch your PH.

 

[GeorgeSmiley]

I now get why people come in and still ask very simple questions....... even a little out of my element and it's a whole new ballgame. I'm just really surprised the 5gal rooted out so fast yet the plants are still failry small. Maybe from all the supercropping they just look smaller lol

I really, really hope the 15 gallon aren't rooted out, I have no way to pull it and really no way to transplant it and still have yet to start flowering

Thanks

That is not true. Root pruning and raking can dramatically increase
new growth. Take your completely root bound plant, take a very
sharp knife and trim around the sides and bottom of the root ball about 1/2-3/4"
and put it back into the 5 gal pot with fresh soil.

A 15 gallon pot inside is way to large. you would have to veg for
about 4-6 months, lol.

Thanks, I root prune my normal plants before I put them out for the season but it almost makes me cry thinking about sawing that apart Do you do this often? Any die back above soil?

15gallon..... yeah just a week into month 3 right now, was going to veg them longer but it's not working out that way, be good then if I have space for roots when I flip. Won't be using 15's ever again. Will be in 10gallon smart pots and will time things much better in the future... I have a G13XHaze and a HawaiainXCottonCandy that are gonna get tall, I really think I am going to move to scrog screens. I want my damn lights to be even, would love to put in rigid ducting instead of the flex.

Thanks for the help

Something like this 4 per light

That's a good question George.

I never disturb the root system when transplanting either, and I have been at it a long time. I never have any problem with this when I go to a larger pot, but I have never tried to break them up. Almost afraid to hurt my babies when I'm trying my hardest to make them bigger, faster.

I might have to give it try and watch for any leaf problems the first week after the transplant.

I've got a stunted durban and an mtf that I think I'll root prune tonight and see how it goes. I was going to kill them anyways.

I have killed what would have been a pound of bud in plants in the last month. Next round I'm burning the place down for the insurance

Root pruning is one way to control the growth, it is perfectly safe
and also very beneficial for new root development and to encourage
root branching. Try Smart pots or Air pots to veg in next time and
these will air prune your roots,creating an amazing root ball.
Then transplant into regular plastic container for flowering and
your plant has all the roots it needs. It can then focus on huge
tasty buds.

Please disturb it. It will stimulate root growth. People
underestimate the importance of roots it seems. You don't want
long roots circling the pot. You want root branching to penetrate
the middle of your container.
