take a pic and post it so we can see. A 400 MH should be as much as 30" off the base of the net pot. It produces 10K LUX at 2' and you only need about 3500 LUX in veg, so don't be afraid to lift it.

One tbs/gallon does not seem like to much, but can't really tell that way because each nute has its own schedule and concentration.
herbie the love bud Reviewed by herbie the love bud on . question? i started my plants more than a month ago but have had lots of trouble almost every new set of leaves eventually turns yellow and dies once they get to a mature size some of them turn yellow with little black dots. the plants are growing at a moderate rate and have alot of branches. but i cant get my leave to stay green. could it be that im keeping my 400 watt hps to close (little less than a foot) at first i was putting in too much nuits but now im not sure if im not putting in enough. the Rating: 5
