Well I thought I had it dialed in plants are in 7 gallon pots with organic promix with added dry amendments of guano, bone meal , and a 222 mix week 3 of flower and the stretch is over now once again the are dying from the bottom up I don't over water and feed tiger bloom as recommended also calmag these plants are 5 ft tall I wanted to rule out toxicity that's why from the start I went light on everything question is does this look like they are hungry or what? If so for what?IMG_20210727_111331613.jpgIMG_20210727_111351582.jpgIMG_20210727_111402588.jpgIMG_20210727_111413895.jpg

The promix has a little lime,Next time add some dolo lime so you can ditch the calmag.It doesn't look like a N deficiency although your leaves appear pale.Are you adding ewc with your feeds?
edit:Light could be too close,yellow on the top.

It's going to be hard to figure out what's going on and find any quick fix due to the way you amended and are feeding bottled nutrients. Your growing medium is all out of whack. From what you added and what you're feeding you have a very high amount of phosphorus. There is also no need to be adding calmag with the bone meal and Tiger Bloom as both have significant amounts of calcium.

Too much P and Ca can cause problems.

I topdressed with Ewc and the light may be too close they really stretched and it's 600 watts hps on super lumen setting

I am putting serious thought into changing my whole medium like hydro I have been reading up on it seems easier to manage

I switched from hydro to organic,Ive stuck with gaia dry and only gaia dry.Built a basic soil let it cook and off I went.Top dress ea week and have had no problems.Stretch consumes a lot of veg food so Ive stuck with gaia 444 until week 4 of flower and now do 75% 444 25% bloom the rest of the way.Touch wood all is good lol.

And how far away from the light is the affected parts of the plant?

That 600w will only have enough light to penetrate down 3ft of plant material.

The only thing you need to change is the way you're amending and feeding. I would recommend doing some research on plant nutrition and what's in the amendments you're using. Use that knowledge when amending and feeding. Bone meal itself is very high in P and Ca. The Tiger Bloom has calcium nitrate and whatever brand of 2-2-2 is going to have calcium as well. Correct your feeding and things will get better. Switching to hydro is not going to solve anything until you learn how to properly feed your plants. Too much calcium will cause issues.

Your first pic has classic signs of K deficiency. Edges tips browning ,yellow between veins and veins remaining green. But as said above you’ve mixed up your food so it’s hard to tell if it’s lacking or it’s because off too much of other stuff causing a lock out.

Good read,too much Ca messes with Mg and K.Add to that incorrect watering and bingo you got yourself a head scratch-er.

Quick thought I did a major lollipop a week ago cut out a lot of branches they were perfectly fine then could it be shock or just a coincidence
