Do nute schedules depend on the size of the plant?

I have a plant that’s about a foot and a half tall, I used to nute, water, nute, water etc

Then it started getting nute burns on the tips, so now I nute, water water nute etc. All better

Then my other girl is 4.5 feet tall, same strain, just vegged longer, did the nute water nute water etc and started getting some yellowing.

So fuck it, last three weeks I’ve just done nute nute nute nute nute, given it nutes every watering! Color and form is back to perfection, no nute burn

So how do you guys gage how much nute your plants need? The schedules given by manufacturers can’t work for everyone Id imagine

Well, the larger the plant, and the more vegetation the more nutrients it's going to require. What medium are you using. What nutes? PPM?

I’m in soil. Haven’t measured PPM tho I do have a meter. Will post some numbers!

Both are in flowering so -

Calmag
Base - oneness
Booster - ginormous
Sugar - carbonaria

pH is between 6-6.5 at all times

you're doing it right. judge by the response of your plants.
