Hey my critical kush is 39 days into 12/12.shes yellowing up and getting yellow with brown spots on sugar leaves is this ok? I'm sure i had the same in previous grow. I think it's to do with the biobizz nutrients as it's mainly organic

hello mate, I commented on your other post in the tread - critical kush but I can see you've added better pictures in this one..
I didn't know your were using bio-bizz nutients, are you using there soil too ? there nutrients have low calmag if any calmag in, that's why they ask you to use there veg and bloom together in flowering.. to treat a cal mag issue at this point isn't worth it mate as it could harm your buds growth.. she looks fine ! but just so you know I would say not to use bio-bizz in the future, plant magic has a great organic nutrient line that I swear by. I hope this helps.i know this info as I myself have been running bio bizz nutrients and had the same issue.. but yeah your plants perfect bro keep up the good work.

I seen one of your critical buds looks grand how did she smoke?.im glad someone else has similar issues I have used biobizz since day one and always had yellowing I did provide epsom salts 3 times because I know biobizz lacks it but didn't give enough by the looks of it.im hoping in next few days she plumps up thanks for ur advice mate and get those pics up

typical biobizz problem I always thought that yellowing leaf is nitrogen/mag diff
here a poster reference for you to compare CannabisPoster4000.jpg
 
Here is a shot mate, as you can see the yellowing in the leafs, it's had this since day 31 of flowering. Honestly don't worry about it :)

What did you yield mate she's supposed to put out a good amount
i haven't cut her down yet mate, but she is going to be a very nice yielder for sure.

It might help, I doubt it. I got one that it happened to. It just dropped the fans early. It finished with a slight loss on yeild. Just keep in mind and remember to treat early next time.
There still plenty of fans there I lose about two every 4 days that's when they completely yellow though. I have magne cal by plant magic might give her a dose see if it helps doesn't seem to be happening rapidly.would it cause problems this late in or shall I leave her be ?
