Personally I would say nutrient lockout rather than one specific issue, check the run off ppm and Ph and adjust accordingly then feed at half strength.
PK and calmag are both notorious for causing lockout in the medium

Yellow Cotyledons?NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?Leaves. Color - Yellow

Nitrogen toxicity mid-flowerSo I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?3 years ago

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now.
It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.3 years ago

Yellow/Brown/Spotted/Crispy Lower LeavesWhat is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.3 years ago

Deficiency or Nute Lock?I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.3 years ago

Been flushing for the past week, the larger fan leaves are starting too turn yellow faster than I had anticipated but trich's haven't started turning amber yet. All the other sign's point towards her being about a week away from the chop but I'm a bit worried that I flushed early3 years ago
