Those single blade leaves on top are a sign of re-vegging, either a light leak, inconsistent lighting, or extreme stress. Your best shot is to re veg until you are able to take clones or scrap and start over.
It's been cold front, sun, cold front, sun.
Very inconsistent weather patterns in STX lately.
Warm then cold, wind.
Basically just bad.
Re-veg is better on my ego than hot soil, or nute lockout.
