Think i have found my seedling problem, biobizz light mix soil??

I have threads I have wrote about where I thought I overwatered my new seedlings, but now I think I may know why My seedlings have there first two leaves get brown dots and then the leaves start dying or burning I guess. Look at this website. This is the soil BioBizz LIght Mix. That I am using and it says it is "Slightly fertilized it ensures a fast development of roots and vigorous new growth." Could this be how they are getting the leaves the way they are from the slight fertilized mix. Could it be fertilized this way for root development in clones? Thanks for the help. I have went through 10 Blueberry seeds and ended up looking the same as these 6 whitewidows that are not looking good.

That soil is probably what you transplant a bigger plant into so it can handle the amount of ferts in the soil.

i use canna terra soil iwas using my homemade compost with perlite and had nothing but problems i changed to canna terra and thats got nutes in it and got no nute burn from the soil just rapid growth hope that helps

I am guessing the nutes in the soil may be to much, I am not sure what to do. I wish I knew for sure if it was the soil.

Does anybody else have input on if the nutes in the soil could be messing up my seedlings? I read where seedlings are supposed to get no nutes for the first 2-3 weeks so my only guess is the nutes in the soil is screwing them up.

Use the cheapest starter soil you can find, something with no chemical nutes at all, once plants have grown 4-6" tall you can transplant to a hotter soil , by hot I mean soil with fertilizer in it. You should only have to water your plants once every few days when they are small, if your watering every day your most likely causing root rot.
