Hey there FTLS, I've gotta disagree with everyone here for once. It's clearly K lockout, this you can tell from the K deficiency symptoms even though you're adding it. The colorful discoloration is the dead giveaway. You know it's not Molybdenum because it's never that one lol also you're adding plenty of specialised minerals and i'm pretty sure they'll have that in there in some form or another. It's not pH because of the more "even" yellowing, the yellowing would be more patchy and unpredictable if it was pH fluctuations. So it's K lockout, probably because there are several NPK nutrients each with their own K you're adding to the feed. The bad news is it's gonna get worse before it gets better , try removing NPK from the feed as much as possible and hope the plant bounces back on it's own time probably two weeks. You can also flush by watering until runoff , then adding 20% more water. Most of the time it's just as quick not to flush , though. Hope this helps ! 🚀
