This is one of my CBD Therapy. I have 6 plants, 3 different strains, and all look pretty good but this one. Top looks ok but some of the lower leaves are curled and not recovering. Here is a photo of the top and the sides where it is curling. Weird that the other plants don't have this and it does not appear to be getting worse. Anyone have an idea what this is? Thanks much in advance!

Oh yeah...using Fox Farm at 1/4 strength but stopped as soon as I ran into this. Only used nutes the last two weeks of veg. I am using FF Ocean mix and I did not feel they needed anything.

Yeah it definitely looks like N toxicity. I think the CBD Therapy must be funny that way. Mine also looks N rich - and its halfway through flowering already- has had very little N other than what's in the bloom nutes. All other plants are fine and have been fine on this diet for years. My plant isn't nearly as bad as yours but OF has quite a lot of N in it. Im growing soilless so I don't have any N in the medium other than what's in the bloom mix.

Thanks Weaselcracker! I have some more of the CBD Therapy seeds. Next time I grow them I will most likely change the soil up! She does seem touchy but she smells sublime! Cheers!

Yeah mine's starting to smell nice too. A happy surprise because I heard someone say most cbd strains don't have a nice smell- not sure why that would be. But it's obviously not true in this case.
