You need to listen to ^^^^ this guy about your PH .....its so important.....if its wrong it will lock out your
nutrients from your plant ( your plant wont feed ) and you'll think you've not added enough nutrients..... So you'll add more to the water and nothing happens and its just problem after problem which could have been fixed with the right ph.......PH VERY IMPORTANT!!!
any
nutrient deficiency needs addressing from the PH first.
Im actually thinking of going
hps now after reading you can get 100/150 watters..........looks like were both gonna learn from these hydro vetrans
