What a train-wreck of a thread.
OP, you had 2 very knowledgeable members try to help you at the beginning of this thread.
Couple of quick things...
Your plants are presenting a typical cal lockout due to an ion imbalance.
Plants use a lot of calcium and its immobile. The lock up likely started awhile ago.
Your PPM/EC is too high. I didn't run the numbers, but just by cursing over what you listed, I can see you're likely adding way too much K
( cant recall if floranectar is magnesium sulfate or potassium sulfate.)
For the Si, if you foliar it you can get the added benefits of SI while keeping it in your regimen and dropping it from your reservoir.
I use Power Si or Mills Vitalize (original Aptus Facilitator) but I foliar because silicic acid is very reactive. I like these brands for Si because they provide a higher bioavailable percentage of SI along with some aminos. I drop this around wk 2 of bloom.
I think you already know you've gotta simplify your feed for your next run. Maybe try running just a solid base nutrient and hold off on the additives until you've dialed it in.
And remember, manufacture feed charts are designed to market products. Ditch em and go by your EC instead.
Understanding your elemental inputs will take you much farther.
Oh and FTR, Dynagro has been around for a long time. Its not marketed toward cannabis growers (a plus) and its a complete formula that many growers have success with. Check out the side by side comparisons homebrewer has done. They're a great read
.This here is the best advise thus far. charts are trash, EC and PPMs are your guide as well as reading your plants.
