not magnesium for sure

your plant is a bit dark green, too much nitrogen

i think it's a potassium deficiency, even if i never had one

potassium and nitrogen are antogonist .. too much of one will reduce assimilation of the other
you need too reduce your base nutrient and give some pk boost until the end

I fed epsom salt with my last watering and the discoloration seemed to slow but we shall see.
Also yeah the 2 part humbolts secret is kinda high in nitrogen , it says use equal parts through grow but as flower goes on I don't see needing high nitrogen like it is combined

Also the leaves have been this dark since baby

you need to add a pk booster to your schedule
pk 13-14 decrease nitrogen ratio of the mix and add phosphrous and potassium

5 4 3 yeah my fault and yeah it says use equal amounts whole grow. I used dynagro 2 part and AN 3 part as well but went with this when I ordered tent just because haha figured worth a shot
I'm gonna wing it to try and get back on schedule to finish and do some more research on a feed schedule or possibly was thinking of trying a super soil. Not 100% sure which yet
What do you think

Yeah thats not a mg deficiency.
Mg characteristically is intervenial chlorosis. What you have is edge burning. If it was just the tip, I would say nute burn, but since it climbs around the edges on the side, it does look like a potassium deficiency.
They are right, if you are in flower your nute regimine is way too high on N and not enough P-K. That is why your plant is super dark. But your showing potassium deficiency. What is your PH of feed and run off?

Honestly haven't checked run off lately dumb. I know but ph is 6.7 normally , and I fed today with light part A which is high in nitrogen and a full dose of the B with pk

Shows for flower as well but probably will get a bloom booster of some type for supplement overall , besides being high in N they seem ok its a user error on me so I imagine if I find a booster should help ??
Ty in advance for the noob questions lmao

Thx i ordered today so just scale down my base nutrients and add that to make the ppm I would normally feed?
Edit lol I imagine after thinking since I have high N atm probably just use straight bloom booster or whatever it was called haha because I don't need N atm.

yeah your soil is already rich .. next watering give half dose base nutrient + half recommanded dose of pk, and see how they react
