I think it was more related to the soil I was using....Nectar nutes don't appear to play well at all with foxfarm oceanforest - soon as I switched back to Nectar #4 they went right back to being happy.
But from what I've read and been told - LEDs full white spectrum cause the plant to need more micronutrients than MH or HPS do, and I noticed my ladies were eeeeeating up the magnesium, I've since been adding in 2-3x the amount of magnesium that I ever have before and they're back to normal. So that's the only real difference I've noticed.
Since I flipped to bloom, they stopped showing the 'need' for anything.....just looks good all the time. Veg took a little more effort to keep them looking 100
