Hoping this is a thought experiment :)
> For macros, sunflower seeds (2800 kcal of sunflower seeds for $3 at Trader Joe’s), mostly Omega-6 fat, but https://www.health.harvard.edu/newsletter_article/no-need-to-avoid-healthy-omega-6-fats suggests that’s fine.
There is no need to avoid omega 6 but that doesn’t mean eating 100g of it a day is a good idea :) MUFA’s & PUFA’s are healthy fats but you can still eat too much of them.
You are also approaching the toxic dose of B3.
> For Omega-3, ground flaxseed is a good source (2400 kcal for $5 at Whole Foods)
If you only consume ALA (sources not from the ocean only contain ALA) you do have to be careful of how much omega 6 you consume as they compete for the same enzymes in synthesis of the non-essential PUFA’s.
> For most vitamins, organic spring mix ($4 for 1 lb on Amazon Fresh)
You are going to need to eat a small mountain of that a day. I love leafy greens but they mostly exist to add texture and fill space on the plate. You are looking at needing to eat around 2lb of spring mix to hit 100% on the important vitamins they offer.
Not even remotely. Supplements won’t make up for the diet in the big picture.
Immediately lacks animal nutrients. Especially quality protein, iron, vitamins, etc
Low omega 3 (especially since we can’t really convert plant omega 3 to EPA and DHA) in the grand scheme and higher omega 6
Low B vitamins and D3.
You’d have awful digestion since humans aren’t built for seed consumption.
No, what you describe does not appear to be a healthy balanced eating pattern.

Make sure you use ground flax seeds or flax seed meal never eat seeds whole. Also I mix water into a paste of flax meal, Chia seeds, and nutritional yeast. A 1/2 block of Frozen spinach drained is easier to deal with IMO. Make a nice wrap with those ingredients plus some meat if possible.
