What should I do for yellowing of new growth?

[Broccoli]

HI and thanks for your time.

i have a seedling that is growing slow and its new growth is yellowish. Not sure what i should do.

my grow journal is here

Broccoli's Journal. Soil-LED-Tent-Auto Caramelicious 2017

around a week i took note of the light color of this one and took a pic.

here it is now at 16 days.

??? Any ideas ???

I'm no expert on nutrition or deficiency but could well be she's not getting enough nitrogen. I'd try feeding 1/4 strength veg nutrients and see if there's an improvement after a couple of days. Are you letting the soil dry out between watering? I've had seedlings look a bit weak and droopy due to overwatering.

i will try 1/4th nutes today and keep an eye on her. Watering has been a challenge due to the soil i used (fafard premium topsoil) for potting. Im watering light not trying to soak the hole pot at this time. Thanks for the help!

If your soil isn't draining well, you may want to try poking extra holes in the sides of your pot near the bottom, this will help water drain, allow more water to evaporate from the soil and allow more oxygen to get to the roots.

Your soil looks bare. No perlite, no fluffy soil. When using a fertilizer you need to mix it with a base potting soil as well. Lack of nitrogen! You can recover it by getting some real potting soil and put a layer on top and water it in. Don’t add a bunch of nutrients. Try adding hi nitrogen potting soil and just water it in. You should be fine in a few days.
