Undergrowth Die-off From An Otherwise Beautiful Tahoe

[Seraphina]

Hello! This is my first year in raised beds (outdoor). My singular Tahoe is starting to show some leaf die-off in the undergrowth, and it's only a week in flower. Leaves are mottling yellow, veins are yellow, some leaf segments more affected than others. Large necrotic areas on the leaf edges. All other foliage is beautiful and healthy, constantly praying. I can't seem to find any similar pictures of what I'm experiencing, and I'm dropping some pretty high ppms so I doubt it's a deficiency, maybe lockout of some kind? I keep the feed pH between 6.5-6.7 Feeding w/ a 5:10:5, pro silicate, calmag, kelp extract w/ yucca, supplementing w/ biogenesis' mineral matrix. Ppms come in between 1,000 and 1,100 and I always feed right after I water. Last week I fed with just a 4:26:26 and the kelp/yucca Haven't tested soil pH, so that's next on my list.

Sounds like beginning Mg but it's hard to tell without a full plant pic.

Show us the whole plant, not just a single leaf.

Has it been hot? How big are the beds? Why are you feeding so hard in soil, outside? Show us. Everything.

It has indeed been hot, highs from 98-113. Then we've had some uncharacteristically cold nights, lows in the high 40's. Southern Oregon weather is awesome like that.
Last week I was feeding with Age Old Bloom, Soul Infinity, Botanicare CalMag Plus and ProTekt, supplementing with BioGenesis Mineral Matrix. This week I switched from age old to Botanicare Pure Blend Pro. There are 4 plants per 30x5 bed. I water each bed with 109 gallons of water before I drop 95 gallons of my nutrient mix, which I pH between 6.5-6.7 and ppms come in between 1,000-1,100. Two weeks ago I fed with only Infinity and Sea Grow (4-26-26), ppms were coming in around 800. Before everything started flipping two weeks ago, I was regularly spraying with Companion with Protekt as my surfactant. In the last month I have been spraying OG BioWar Foliar Pack and also a mix of Cytokin and fish protein powder (15-1-1).
I'm feeding everything so hard because a lot of these plants are 8-9 ft tall and wide, the Tahoe is one of the smaller ones). I'm worried that they've maxed out the beds. The root mass is rising up the plants, they look like they're lifting themselves out of the beds.

Just keep the mulch on them as you are, keep the watering even. Inners and lowers yellowing and dropping is normal given the reported conditions. She looks fantastic!
