Hey guys thanks for the replies.

I too suspected the ph in the soil was off, so I bought some Espoma organic soil acidifier, but i didn't add any yet. Is this stuff safe to use? As for the ph meter it's a HoldAll moisture/light/ph meter with two probes that stick into the soil. I know nothing of the quality or even how much it cost since my roommate bought it, but it does look rather cheap. I plan to hit up the gardening store tomorrow, any brands you can recommend?

Thanks again
knubie Reviewed by knubie on . 6 weeks in, only 4 inches tall Hi everyone, first time poster and grower here. I have two different seeds planted (rocklock/lemonskunk) and they are both having the same problems. These guys sprouted about 6 weeks ago and seemed to be growing well (albeit somewhat slowly) under CFLs for the first two weeks. Then I added a 150w HPS. I had about 6 leaf sets on each plant, but eventually the tips started drying up and dying, at the same time the plant just stopped growing. It did this for about 2 and half weeks. About a week Rating: 5
