Tried to get the best pics I could. The top has real thin yellow spindly growth coming in. The leaves are not right at all...

what kind of nutes are you using. zinc is a trace element so its in the nutes you use if any. it looks like an mg deficiency or your using nutes that are affecting the flowering of the plant. you could be using high nitrogen nutes when you should be using nutes that are balanced different for flowering

I havent grown auto flowers but I have had plants look like that before when they were starting to flower and too close to the light.

Looks pretty normal to me if the plant is growing quick. Usually new growth takes a few days to catch some color.

I would be more worried about your leaves tips curling up. It says something, i think about humidity.
