I put in two gallons of water, with about 6 drops and an additional half dropper full of nutrient solution, and my plants are definitly responding. I think I even spot a tiny bit of burning, there are some darker green patches. They are growing faster and healthier, they liked the food I gave. Right now I'm a little confused about my MH light, its taking awhile to power up and I don't know why.Its been about a half hour, it hasn't powered up yet.

also, is it possible for a 5 internode plant with aobut 10 sets of leaves to be burned by 6 drops of nutrient solution plus and an additional half dropper full? I mean, I see that as like, 1 ml... I am getting a tds meter very soon.
