Also, a 400W HPS may be a little intense for such young seedlings... unless you're able to keep it real close, and not burn them.
yes, there is some premixed fertilizers in the soil but that isn't the problem . maybe is but just for these seeds because its was perfect for seedling before .

i can keep 400 w bulb on 15 cm from plants and not burning them

)

so....premixed fertilizer can be a problem for these feminized seeds ?

because if the seeds was not feminized , I would start with new one but i pay them allot of money so....
