After a 2nd opinion. I usually add Epsom salts (magnesium sulfate) to my res but forgot during this growth. Added now will see. Its a sterile hydro (1000ppm) 2months in under LED 5.8pH and everything else is running well.

Of coarse your ph is good I'm assuming so....how's that cal mag? Of coarse this looks like a deficiency. But from a nutrient lock up due to calmag or due to a low ec. I run the same food all the time. So if I saw this I would wonder if my calmag was up to par and that the ph isn't to high to block out the calmag or nutrient. You will see something like this in early signs of being root bound.... but that's definitely not it lol

Thanks, I have run calmag since early but at a slightly reduced level to norm so I might bump that up a bit. pH is a steady 5.9 so I'm happy there.
Last couple of strains I've had were low feeders and right now my nutrient base was added at 800ppm which could be a tad low.
Will see how it goes over next day or 2 then add more calmag.
