Thanks for the input, mal and polish!

Yeah, I am using the pH down (about 1 drop for a half gallon of water). This drops the pH from about 7.0 to 6.0 best I can tell using the indicator drops. Grow medium is coco coir mixed with perlite, so not really soil or potting mix. From the reading I've done, this is more like a hydroponic deal than growing in soil and coco coir is pretty sterile? And everything I've read says not to add any nutrients until there are more leaves. It does seem like something is lacking, though! I've got the Fox Farms hydro chemicals, but haven't tried that for fear of burning the plants. Maybe try a really diluted mixture just to see? I think the local store carries Dynagro too.

One day after adding the fan... this seems to help things dry out faster, if nothing else. I think I'm seeing a bit of growth now, but maybe that's just wishful thinking? The cup for plant #1 was pretty dried out, so I watered it (first time in 6 days).

8 inches in two weeks? Definitely doin something wrong here.

Thanks for the comments and keep 'em coming. I should know in another couple days if this was just a case of overwatering.
