New growth is yellow, what does it mean?

all the new growth coming out is yellow/yellow-green, while the bottom leaves are more green.

Does anyone know what this means?

it's just a light green...means it's healthy..

I dont think thats the case man. Thanks for the reply though

here is a pic and im talking about the bigger plant of course


the bigger one is only 2-3 days older than the smaller one, its just had more light, well look at the difference in the color... the new growth on the bigger plant is just getting more yellow as it grows, these 2 plants are the same strain too, the big one doesn't look too healthy, I just want to know what the yellowing means, ph problems? some type of deficiency?


if it means anything the humidity here is very low and the temperature can be in the 90s during the day, in the late night and early morning the temp is in the high 60's to low 70s

what are your temps?

mid 80s to low-mid 90s in the day, low 70s (sometimes high 60s) in the late night and early mornings... cant do much about it because this is an outdoor grow mostly

temp is 86f right now (its 10:48am here)
