@Alcurtis93 I usually dilute it some following the directions for houseplants. Also, I repot my plants occasionally too because they get root bound. I usually see plants take off after a good rinse of the roots and a repot!
@mardel i was looking through some of your plants. The echeveria will definitely bloom at some point. Try checking to make sure they aren't root bound, try fertilizer. Sometimes they don't when they are young. Also, I live in the desert so it's like optimal weather for them.
@mardel You definitely can. If they are babies I would definitely dilute. For all my succulents I use 24-8-16 all purpose fertilizer and do 1/2 tsp per gallon. It should have the ratio somewhere on the box you have. Yours may be different.
