Yellow fan leaves. Is this a rootbound prob?

The fan leaves are yellowing and dying. I thought the problem was Nitrogen deficiency. I already add urea fertilizer, 'a lot' of it, and it still yellowing. The pics shows some of the small fibrous root came out of the polybeg. It is just a very small portion of the root. Is this a rootbound problem? I think the pot/polybeg is big enough compare to the plant height. The plant is just starting to flowering.

if it aint nitrogen it can be cal/mag

Is it only that one leaf? if the plant is flowering its expected to have some leaf death, its normal, its putting most of its strength into creating your buds

she looks pretty healthy

I cut all the yellow leaves, i left that for the pics. It's yellowing because of flowering? Should i ignore the root that came out? Or should i transplant it into a bigger pot? Cal/Mg def? seriously?

deff transplant if that is an option and maybe feed the plant or something? She's pretty spindly at the moment. try a shot of PK 13-14 for two weeks boost that bud production. Did you feed that plant at all? Too much shade? What's going on and why is it not more robust?

I use Sensigrow A+B for veg and Sensibloom A+B + Big Bud for flowering. Feed 1 time every 2/3 days/, diluted in water (feed by watering the fert onto the soil, sometimes foliar spray) Too much shade? Imposssible, no shade at all, direct sunlight, sometimes i worry if the plant would die because of the heat stress. My country is super hot. I can transplant it, but it's too big and i afraid if the soil will crumble and the root will expose. I'm not sure what did you meant by 'robust' (my english is poor, lol). You mean that it should be more bushy or the leaves should be bigger?
So, the yellow leaves is definitely because of rootbound and flowering stage, not Nitrogen def? Should i agree to that?

not if you just started flowering it...that would take some time into flowering for that to happen

Any more opinion from experts? Today i pulled 5 died fan leaves and it getting worse.

Looks chlorotic. Are you feeding it? Try magic green from HG.

Oh and I think root pruning is a good idea. But if you prune off roots you need to prune back an equal amount of top growth. It's less stressful.

I'll transplant it. Thanks for all the feedback.

please update when the prob is solved or if the transplant helps

It's getting worse, 4/5 fan leaves die everyday.


I transplated it into a bigger pot. Ignore the hideous look of the pot.



What is weird for me is that the roots not suppose to be that depth for the plant size/height (about 5.5 feet). I think there's something wrong with the root system.



The leaves is getting smaller, the veg stage leaves are twice the size. Maybe the nutrient is leaching, my plants are expose to raining. I'll increase the fert ppm and put loads of urea. Hopefully i'll see some changes in a week or so.
