The phdown sold for aquariums is not made for plants. I made the same mistake before I was told not to use it. If there is a hydro shop in your area, they will have it. If not, there are many places online to order it and it is no more expensive that the aquarium stuff. I am also on a very tight budget so if I kill my plants, the investment for lights, fans, electricity are all for naught... not to mention not having any meds.

I had to make a two hour round trip to acquire the right stuff. But, in light of the potential consequences, I felt it was a good investment in time and effort. Best of luck!
stjr2k Reviewed by stjr2k on . Seedling Problem I have 8 seedlings that are 10 days old and all but one has started their second set of leaves. My problem(s) is that the one seedling that only has first set of true leaves, the leaves are curling at the bottom, the tops are fine (for now?). Three of the other seedlings have started doing the same thing but the second set of leaves are doing fine (for now?), and on 2 of the other seedlings the first set is doing fine (for now?) but the second set is curling. I have one that has no problems Rating: 5
