why is my seedling growing slow in coco?

is this normal all the other seedlings I started took forever to grow clones were way faster at rooting I have been watering with voodoo juice and superthrive ph 5.8 ro water its about 4 or 5 days old think about adding a few ml of sensi grow too the coco was precharged but doesn't look like it helped anything.

I wouldn't feed it anything but root stimulator until you get a few sets of leaves. If you aren't sure. Go get a product called Canna Start. Feed it with that until you have a little plant going (probably 2 weeks). Then switch to your vegging nutrient and gradually bring up your concentration. Make sure you use CaMg if you are using RO'd water. Even if you aren't using RO'd water, you may want to use some CaMg if you stay in coco..

is it normal for seeds to grow this slow in coco all my others did clones went fast tho

You should mix a bag of earthworm castings with your coco brick before u germinate. That will give the seedlings enough food for a good start. Coco doesn't have nutrients, seedlings still need nutrients to grow. Doing this with your clones as well will get you off to a great start you will notice the difference.

next time try fox farm light worrier and ocean forest mix them 50/50 really good mix to start them out

Not sure about coco but I always think the same way the start of every new grow. It takes a good 3-4 weeks to get some good growth going. Esp the first 2 weeks it seems as though they aren't growing.
Something I read here.
"Roots before shoots"

Happy growing

Seeds typically take longer than clones. Your babies put all their energy into developing roots at first, and really don't need any food for at least a couple weeks. After a week or so, when they get their "legs", they will start to grow upwards. Have fun!
