If you don't get a steady schedule down, and if you don't measure everything you put in the water...you will more times than not end-up with a dead plant.

Been a long time, but when I was using Miracle Grow All Purpose liquid, I believe I was adding 1 tsp per gallon of ph'd water, once a week for established plants.

In my growroom that meant 1/2 tsp per gallon of water, twice a week. Something I've done since I can remember. Same weekly totals, but reduces chance of nutrient burn or micronute overdose. And, you can adjust the next mix according to how the plant is reacting.

What are you planning on using for nutes in the flower stage?

Would start off giving 1/4 tsp per gallon of water, twice a week, utill they tell you how they like it.
