well it could also be something leaching to the surface. i read somewhere about bloodmeal doing something like that. are they inside? i know how dry it is there, you may want to try a humidifier to see if you can keep them from drying so fast. the perlite should help it hold water too. is that soil from sedona? got a lot of red to it.
Mal420xl Reviewed by Mal420xl on . Green soil????? Started growing for the first time ever. I mixed in organic blood meal into the soil and followed measurement directions. End of week one after seeds sprouted I noticed the soil started turning green (Moving towards end of week 3). Did the blood meal turn the soil green or is there a problem?? Help!?!?
