I agree if everybody else is okay and you have not changed anything @Hydroman . If it’s not a root issue it’s just her being her.
I’ve got two different Super Lemon Haze clones going right now and one likes light a little more than the other one and that might be your problem here.
Well, anything else I can come up with would just be a somewhat educated guessing. I do see what could be slightest signs of S def. It could also just be your light although it looks like you have plenty of distance. what kind of light do you have? 1000 PPM seems a little on the high side, but that’s just my experience with HFF and coco. In that situation the more water they get the lower the feed number should be. I ran 1200uS-1600uS watering up to 6 times a day(up to 2.5 gal a day per plant). I would probably guess it’s stress related. Maybe a combination of the two? Claw from excess N combined with twist from stress. You might have to search out a good hydro grower for better answers and unfortunately I don’t know who that would be. Sorry I’m not more help
That sucks because i have another strawberry cough in there with the wild child and shes loving it. Next reservoir change ill lower the N a little and pray to the ganja gods.
You should probably find a hydro grower to ask before making changes to nutes. If things aren’t getting worse or spreading then I would stick with what has been working until you can get a more definite answer or find some supporting research on the subject.
Then I would lean more toward light intensity instead of S def. It too is probably ok as long as long as you don’t see her getting worse. With the exception of the twisted curled leaves she looks pretty good. If you see the areas closest to the light continuing to yellow more or twist/pucker then you might consider dialing it back just a little to see if that helps.
