Possible K deficiency. Whats your medium, ph, and what are you feeding with?
Using Biobizz light mix and bio bizz bloom & top max. Not sure what the PH is as I've been told that you don't need to alter it when using Biobizz nutrients

When did this first appear and how long has it been going on?
What is your water pH?
What medium are you using?
What nutrients are you using?

I'm using Biobizz light mix & Biobizz bloom and topmax. The leaves started going like that around 5 days ago and only seem to be getting worse.
This is my first time growing and was under the impression PH didn't need to be altered with biobizz nutrients but I may be wrong.

I would check the ph.

I have personal experience with biobizz... i burned my plants several times. How often are you feeding? There's a genuinely fine line between too much and not enough. Its an "organic" fertilizer based in beet sugar, but its not processed as quickly by the plant as an inorganic chelated fert.
Id just give her plain water for a couple weeks, and then start your feeding schedule back at 1/2 str and work your way back up. 1 feeding a week max is all she really needs. You could do a worm casting tea to increase biodiversity to help break down your inputs a bit quicker in between feedings, but otherwise just go light.
I eventually moved away from biobizz, because even though its "organic" you still end up dealing with all the same BS issues you get with other bottled ferts. Switched to homemade soil with dry amendments, now all I have to do is water.... never looking back
Ahh, I've been feeding every 3 days or so and starting to think this may be the cause!
I'll give it water only for a while and see if this helps.
The dry amendments and homemade soil sounds ideal.. does it have any effect on your yield?
Thanks for the replies everyone!

Ok, so here's what I ended up doing so you dont make the same mistakes...Ahh, I've been feeding every 3 days or so and starting to think this may be the cause!

Give it a FULL 10-14 days without food. Dont skimp here... if it is overfertilized, there will be plenty of nutruents in the root zone. I skimped out here, only waited like 5 days and thought I'd be fine... i was wrong. Ended up REALLY burning my plants.
When your feeding, don't water to run off. If your giving plain water, watering until runoff is fine, but when your feeding, those nutrients get deposited even though the water flows through, so you end up with a build up of nutrients in your soil that can end up being too hot.
Feeding once a week MAX, not minimum. Your better off SLIGHTLY undergoing nutrients than over doing it. Not only are you essentially throwing money down the toilet because your wasting nutrients that aren't needed, but its more stressful on the plant to be overfertilized, and its harder to fix an overfertilized plant than an under fertilized one.
And as far as I go, here is the grow style I switched to: https://www.rollitup.org/t/greens-probiotic-method.985411/
Much simpler in terms of day to day care for your plant. Once its set up, you hardly have to do anything other than watering. Very user friendly if you follow Greenthumbs method exactly. The only thing I will say, is that his soil mixture is pretty complicated. If you did want to go this route, DTE's "Bio-Live" or BAS's "Craft Blend" will save you a lot of time and money sourcing individual soil inputs.
If you want more info on the probiotic method, post in that thread I linked, and me or one of the others will walk you through our processes. Every day is a learning curve my friend, RIU is a great place for info if you know where to look. Cheers!

Hi @BluntMoniker,
What do you mean with “BS” ?
I’m using biobizz for the first time, ( switched from Plagron “organic” ) and I’m having some problems with my crop: yellow leafs with burnt tops. Hard to guess for me if the babies are starving or over feed, because I only use half of the recommended doses of Bio Bloom, Top Max, Acti Vera, Bio Heaven and CalMag ( on RO water). PH 6.2-6.5 / EC 600 ppm starting now the 5th week of flowering.
But I am adding the nutes almost every watering. Is it too much?

BS = Bullshit lol.
And its hard for me to give you an exact answer, because your using many more products than I did. I used biobizz grow and bloom, with some Fox Farm Big Bloom added (because biobizz has almost no trace nutrients in their base line).
Pictures might help. Generally, yellowing from the bottom up is nitrogen deficiency, but if you have yellowing with burning, it could be nutrient burn, pH issues, or possibly something else. Based on what your telling me, your far from over feeding, and pH is likely not the issue, so its hard to say without some pictures.
Also, you have to realize different plants react differently. 1 plant may love what your doing, another may starve, and another may burn. Plant biology can play a big factor in this stuff, which is why normally you start low and work your way up in terms of feeding.
What I will say, is that feeding every time is what did it for me. Once I switched to only giving food once weekly my plant did much better

Hahahahaha ... ok, ok! I need to improve my english
BS = Bullshit (noted)Thanks a lot for your quick reply mate. Now the babies are sleeping, but I'll take some pics and post them here when they wake up
Best regards.

No problem. And yes, please do, and I'll do my best to offer advice, or I'll get some people in here who can give you the advice you need.Hahahahaha ... ok, ok! I need to improve my english

Damn man... the whole plant is turning yellow.
But now that I have a larger view of your plant.... what size is that pot shes in? Looks awfully small
The pots are smaller pots I think, unsure of what they hold other than that it says 24cm on it. When I planted these I didn't really have a proper environment for them so wanted to keep them smaller.
I've since bought a better light & tent etc so have more room now.

Fuckin awesome piece of info!! Thank you! I can back up this part:
"When your feeding, don't water to run off. If your giving plain water, watering until runoff is fine, but when your feeding, those nutrients get deposited even though the water flows through, so you end up with a build up of nutrients in your soil that can end up being too hot. "
I have dealt with that. I always fed a certain amount.. then seen so many ppl say to feed til 15-20% run off.. so started doing that and immediately noticed changes. My plants weren't so happy anymore.
I'm still new to the game and I'm learning a lot by trial and error. It's the only way to go IMO. But when dealing with a living thing like a plant... i can't just plant it.. see it sprout and just let it die.. I wanna see where I can take it, and in turn see where it can take me in the world of cannabis growing. I ain't no Leo Dicaprio.. but I can't let a plant die if I can help it at all. That's what brought me here to RIU. I was given the link years ago. I had it logged under growers nation.. was this site ever called that? idk if you would know this.

I dont know about the site's name change honestly, not been on here long enough for that.
And yea, thats exactly it, its all a learning game. And what I learn and teach, may be completely different from what someone else learns and teaches.
Were all just taking our experiences and trying to help each other really. Some advice may be better than others, some people might be more experienced in certain things than others... RIU is a great site

you need to get some mag in there at the roots and you can foliar feed it.
pots seem small to me as 24cm = to about 9.5 inches hard to tell in the pics if it is small as I cant see the plant with the pot.. Might be a reason.
Plants were under fed during veg thats why they are yellowing out ...plus seems like they are still being under fed during flower.... plus small pots plus probably dont have any microbes doing their thing in there. Over watered root issues are the second guess root bound if the pots are small.
I suggest flushing the pot out thoroughly renute at half strength and add about 200 ppms of mag to that and water that in and add microbes to it. Then maybe do a water feed water feed water water feed kind of routine.
You water in at a ph of 6.5 you do need to check that you dont need to check run off or the soil ph the microbes regulate the ph for the plant at the root surface.
Dont be chasing rabbits down a hole, you need to flush renute, add mag, add microbes and just leave it alone till next watering, and just nurse it to the end and learn from what these did and how to correct it for the next set.

Dear @RI412
Now that you have the attention from a couple of experts like @Bernie420 and @BluntMoniker ... Do you mind if I publish here in your post some pictures from my plants?
I'm also on Biobizz, and they look similar to yours...
