hello every one, im just curious, how do i know if my plants are taking? they are planted firmly, the roots are covered, water temps are good. but some of my jungle val are starting to turn brown. i planted 5 plants, and 2 of them are almost half brown already. only one of them, has one leaf that is compleatley dead. does this mean they are not taking, or maybee they are not getting enough food? any help would be great.
