do they look underfed?
It really depends on a lot of things. How hot is your soil to begin with, how old and what size are your plants, how large is the container they're in, what strain are you running, how strong is your light... etc...
If your plants look healthy I wouldn't just double your nute strength because that's what a chart says. In fact, there are many people running grows with water only, some through to mid flower, some all the way through. With my current soil mix, the highest I'll probably go with any nutrient water feeding is somewhere around 450-500ppm with a .7 conversion tds meter.
edit: generally it's much better to underfeed than overfeed. I know a lot of people like to pump the nute levels as high as the plant can take but in my experience, there's a finer line when pushing the maximum than pushing the minimum.
Thanks for lookin out man, im not planning on doing that. I imagine its way easier to add nutes than it is to flush them out..especially with soil lol.. I started them at like 200 PPM and worked them up to 350-400 so far... My White Widows do seem a bit underfed tho
I posted this because im about to start using Open Sesame/flowering nutes and it made the water super red at low PPMs haha, i was mainly making sure that i wasnt overfeeding...
edit- just for the facts..lol

"there's a finer line when pushing the maximum than pushing the minimum" thanks for that piece of advice as well
