Nutes/Res Question

I had 2 questions concerning PPM's.

1) First, is this accurate?
Seedlings 50-150 ppm
Unrooted Clones 100-350 ppm
Small Plants 400-800 ppm
Large Plants 900-1800 ppm

If not, please correct :leaf:

2) If I feed my plants say friday and my nutes have depleted a few days later... should I fill the res with water, take a reading, then calculate nutes to add to get my PPM back up or should I just add water to tank and wait till the week's flush/res clean and then start with slightly stronger nutes? Im just not sure if I need to have my PPM's at a set point for a week or if I should feed then wait till they finish the week then re-up~
 
Those ppm ratings look good maybe a little high except instead of Large plants that should correctly state Flowering plants. i typically top off my tank with water until the ppm drops to the low end of ur chart/or discolouration happens. then i do a res reset/flush with the same ppm
Ph as often as possible 5.8 in hydro
 
Okay ill stick to those PPMs and then wash/re-fill/re-nute when I reach the lower side of my scale. Which is a res clean/flush once a week right? Ive heard of people going the whole veg time without washing out their res??
 
typically my veg plants havent eatten through my nutrients in a week usually more like 2 weeks because i dont have a R/o water system in that house carrying water is a bitch. i simply rinse with really hot water from my shower and refill/renute
