Hi, feeding according to attached chart,100l rez and starting ec is 0.0 (using RO)
EC is 1.4 once all nutes added(not including canna boost) but i also need to add 200ml of cal mag which bumps e.c to 2.5 (2500ppm) does anybody else feed 2500ppm , what should my e.c be at 5 weeks veg, just switched to flower? is this chart wrong or giving me incorrect dosages?

2500 ppm is WAY off the charts for nutes. You'd better flush those ASAP. Hopefully they will recover. Don't give them anything but clean water for the next two weeks. When you start back, don't go over about 1,200 ppm. Less is much better than too much.

Holy crap that's a lot.

Whenever I use nutrients, I only use about 25% of what the bottle says because it seems that all manufacturers have a weird idea of what will work best. After all, you can always add more nutrients later on, and it's harder to take the nutrients away once they are in the grow.

Flush!!!!! Like, a lot.
