Till you can get the cash for a ph pen, I'd go get a freshwater aquarium ph test kit. They run about $7.00 or so at most pet centers.

Might also be from overwatering.
Rusty Trichome Reviewed by Rusty Trichome 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
