Might be but normally the new growth would be dark as well correct? And what about the older leaves curling up? In my experiences they all develop a sharp hook on the end when N abundance is an issue, and i used to use guano so I have seen my far share.
I've had something like this on specific plants as well. I've always put it down as slight N toxicity. I think when they become too dark and thin when it is severe toxicity. I wouldn't worry too much about it right now. See if it evolves. Mine went away in a matter of days. Bump <-- I'm sure someone can come up with a better answer
I excluded this info because i have had this problem in various stages at which temp humidity and nutes are all obviously different...I was just wondering if anyone had a similar problem with the exception of over/under watering....as far as my choices of nutes and soil...I use FFHF till w6 then transplant into FFOF 2-3 weeks before flower both with added perlite 20-30% and nutes I have tried guano with a starting mix of 5-5-1 + potash 0-0-5 + kelp extract + 5-10ml cal mg....also tried with regular FF grow big and big bloom... just started with tiger bloom for the first time....as I stated before I have some 12+ other strains that have had no problem with any of my methods. So not quite sure what I'm doing wrong?
I have two growing areas one of wich is all organic the other I use the FF nutrient line. I Grow a mixed variety of strains in there and so far everyone loves the nutrient line except my 2 Big Buddha Blue Cheese. They cannot tolerate the slightest bit of too much food, and if it accidentally happens they have done the same as yours even worse. It's doubtful that any of this will help you but it is an observation not a guess in my case.
It does help actually. The first time I grew this strain it came out a lime green compared to all the other strains....I figured it was a lack of nutes but it seems it just has very different needs, possible light feeding. Just seems weird that the only strain that seems to be more stativa is a light feeder.
