I've got one lagging

This is my first time growing. I ordered 4 Super Silver Haze seeds and I germinated 2 and planted them 6 days ago in solo cups. I'm doing a coco coir, cfl closet grow. I've watered every other day with the first containing some calimagic and the second being calimagic and 1/4 strength nutrients and the last being just plain PHed water. The first one seems to be doing well and looks healthy though I'm not sure what the rate of growth should be. The second looks smaller, unhealthier and the tiny leaves look a bit rough. I'm wondering if there is anything I can do to save this plant and maybe possibly catch it up to the first. Please let me know if you have any questions.

I'm on day 12 and no nutes. Be careful with the nutes. You don't wanna fry your babies. My opinion would be to lay off the nutes and it will recover.

Thanks, I haven't watered since this post which was only PHed water and it seems to be recovering nicely although the tips are kinda dead looking. I read that every 2 days is a good time for watering but also that the soil should feel dry up to one knuckle deep. Today falls on 2 days but the soil underneath the top layer still feels kinda moist to the touch. Would it hurt to go ahead and water anyway since I have good drainage? I'm on day 7 and I hope it looks that vigorous by day 12.

Ye be carefull not to water too much

Both of these took the words right out of my mouth. First, no more nutes. She wont need nutes for at least the first 3 weeks of her life. Youll burn them all with nutes roght now. Secondly, dont just automatically water every other day. You should only water when your plants need it. Stick your finger a couple inches in the soil and if its dry that far down then water. Overwatering is the biggest mistake new growers make.
