That should work fine.
If your RH is low I'd drop your ppm. I have chronically low RH here and that makes your plants suck up a lot more water and more salts with it that get stored in the leaves. Then about half way thru flower toxic salts buildup can raise it's ugly head and the fan leaves start to go all yellow/brown and get thick and crunchy dry. That keeps working up thru the younger leaves and even into the little bud leaves at the end. Normal yellowing in late flower the leaves go yellow and limp but stay soft and pliable until they do dry up.
Another sign of that is the edges of the leaves curling up and eventually inwards doing the 'taco' or if Canadian, the 'canoe'.
The leaves are doing that to try to cool down by exposing more surface to evaporate more water but that draws in even more nutes/salts. So if the top of the canopy is a bit too warm the upper leaves may start showing that toxic salts damage before the lower leaves do. The salts overload is cooking them from the inside so the whole surface of the leaves burn unlike a sudden overdose of nutes where the tips along the margins of the leaves start turning brown and work in to the center.
After the stretch I switch to Lucas formula style feeding with AN 3-part but keep adding Big Bud until the end of week 5 as I said. Now that I also have the Green Terra Rock steady, 0-0-62, I use that to boost the K even more after the BB stops. Plus extra sulphur for resin in the form of Epsom salts or MSM. MSM is supposed to be an organic form of sulphur but with a name like MethylSulphonylMethane I wonder. You can buy it as a supplement at drug stores and health food stores for joint pain. Usually in 1000mg caps that you can open and dump out. I'd put one cap/L. That's 1g/L which I use as I bought a pound of it 5 years ago and capped it. Didn't seem to help so I'm feeding it to the plants now. Still have half left.
Getting late and I'm typing everything twice to get it right. The Hindu Kush isn't helping much either. I swear my fingers are going dyslexic these days.
