can you post some pics? that always helps

we need detailed info, what are your temps?ph?watering how often? how much each time? how much *baby bio* did you put in? how often have you been giving them it? how about some info on the *compost*?

Some more details would be nice mate, but really we need pictures... could be a few things...

What i think you have done is "burn" the roots with a to strong of a fertilaser/water mix. Try flushing with just pure water (bottled distilled water, or leave a container full of water overnight so chlorine and other traces are removed and water with just that for a few days
