my sprouts are about 4 days old and all the exposed perlite on top of all the pots is turning an orangy rust color. this happened with my last grow (which i had ph problems with but turned out ok) and on my last grow i used ff ocean forest. this stuff is some random off brand starter soil and the plants are doing ok but I was wondering if the perlite was trying to tell me something. its only the exposed parts. when i turn the peice of perlite over it is still white underneath. i found some ancient thread about it but the question never got answered and then the thread died. i'm using plain tap water and it out of faucet ph is always hovering at 7.0
