Is it true that the stem tells you how much nutes a plant can handle¿

I was in another thread and read this post

Doctor Cannabis said:

That's just simple N def. It sometimes looks a bit strange (very white eith still green veins) on Super Silver Haze, usually when the stem is purple or red and not green.

Actually, the amount of nutes a plant can handle is indicated by the diameter of the stem, not strain or height or number of leaves. That's why a mature 1 1/2 foot tall white rhino can take double the amount of nutes a 5-6 foot tall SSH can.

But by now you could go full strength with the nutes, those SSHs look mature enough for it. Introduce the higher concentration gradually, not all at once.

Is this a true statement?

Not true, but true. If the plant is bigger than yeah, it'll take in more nutes, because a fat kid eats more than a skinny kid. Think of it this way. A big plant will use more solution in a day than a tiny plant, but the ppm still has to be the same.

The amount of nutrients to use is different by strain, and anyone who says different hasn't grown more than one strain (that are different enough to count).

I have a girl with a stalk the size of a 50 cent piece and quite honestly I still can't use full strength nutes without burning the plant, but I do have to replace the nutrient solution every 3 days because of how much she drinks. It use to be weekly, and before than 1.5 weeks.

yeah I thought that Cannabis Doctor was a little wrong.

yeah good rule, bigger plant usually take more.
