A few plants are hanging on but the sun is just baking the clay pebbles and frying the plants. I need cooler air to get the plant large enough to canopy over the cup of pebbles

Planted 25 1" grow blocks of Dwarf Siberian Kale.. I have leaves on the germinations in two days! I am hoping to get them in the outdoor system as soon as possible and think there will be cooler weather. Maybe I will get some baby kale.

Can anyone advise on what nutrients I should use for the Kale?

I have these:
