Why the first true leafs turn to yellow?

[神秘人]

All of my girls have this propblem, while they are growing their first true leafs are turning to yellow, whats wrong with them? is the temperature or the fertiliser? or lack of some elements? PLEASE give me a hand!


its obvious that this one is much smaller than others, why this happened? this one was in this condition since burning, is the condition likely to affect this plant's growth and the yield? do i need to do sth to this plant?

What's up old friend? Glad to see you got a tent and are out of that cabinet with the light mover.

Yea, a little bit of nitrogen is all ya need. 1/4 strength though, don't go over feeding them

Good luck and happy growing

Wow! you must be the guy who want to chock me out by your ass LOL! i miss you big moustache, my fertilisers do include N, my fertiliser method is that combinating three basic fertilisers while the plant's growing period. now it is the germ period, i think i need to add more n to my fertiliser solution!　ｔｈｘ
