Are these okay?

Soil - FFOF
Lighting - cfl 24/0
Age - 3-4 weeks from sprout
Nutes- none added yet




I just wanted to address a few concerns with my babies

Notice the top leaves curling and growing upwards?





Then this one's new growth coming in looks a much lighter green


And finally, the new growth on this one is curving



Hopefully I'm just eager and paranoid. Also, when should I start adding nutes? Should I wait for the plants to tell me they need em?

Thanks for the input guys

Its just new growth, the leaves will straighten out as they get bigger. Ocean Forest is pretty hot so Id wait 6 wks to feed, or showing any signs of deficiencies

What could be causing the curling of the more mature leaves in the first and second pictures?

its just growing and praying to the light source . it is fine , dont love it to death , its a weed . good luck
