want to add a lil nutrients

plants are hitting a month old in a day or 2 and im wondering if adding a 1/4 solution of miracle grow would be too potent i figure if they tell me 5ml of MG for 4L of water then id need 1.25ml of MG for 1L of water then to make a 1/4 solution it would be approx 0.3ML of MG per L of water is that too much or too little

I wouldn't recommend using any Miracle Grow solution. If you're going to add liquid nutes buy something that is developed for cannabis. MG may or may not work but it is not intended for our kinds of gardens. 2 cents.

it might take a few more threads to convince you...but the masses will agree with @Dudemankidson
