Hello all

I think my plants may be ready for their first feeding. This is based on the yellowed appearance of some of the new growth. They have been above ground for about 12 days. The soil is 50/50 by volume pre-fertilized potting soil and vermiculite. They are under 110w of daylight CFLs. I have been watering every 3-4 days. I have been misting daily, especially those without their second set of leaves.

Any advice would be appreciated. I know the soil mix was far from ideal and plan to change that when they transplant. I am considering fertilizing with 1/4 concentration Alaska fish emulsion because I am interpreting the yellowing to be a sign of nitrogen deficiency. Should I wait longer to avoid burning them?

Thanks

First picture is from this morning and the yellowing is most visible on the one in the lower left corner.

Second picture is from yesterday and is a blurry picture of an injured leaf (cause unknown).

Third picture is of the outside of the 2' x 3' x 5' grow box (shows vent fan and closet).

Fourth picture is the inside of the grow box (shows plants, circulation fan, passive intakes, thermometer, and timer. Lights are raised out of view.)

Fifth picture shows lights (3 x 30w Twister and 1 x 20w Twister CFLs in a clamp lamp) lowered to normal distance from plants.
