Is this plant healthy

I have 3 yellow and 4 blue now so ure saying i should put 3 blue for the small autoflowering seedling and and yellow with one blue for the big plant ?
 
I think i figured out what the problem was im getting a zink defficiency now so its either phbor temperature thats wrong, its cold here so i put a heater close to my plant and i think they grew a bit il know for sure by tommorow
 
Hello again, I have a 2 questions first should I be trimming those big leaves to get more light through, also my other auto blue tooth is looking very a strange to me but also very beautiful. It looks like it's over watered but it's not the leaves just grow in curly way is that normal ?
