Help! Not sure whats

So she just started preflower last weekend. Watering on schedule/lil more due to heat. Have shade if needed. Or is this just color change before flower due to new growth? (Sounds stupid but I know what I meant)

I'd be more concerned with the white on leaves. Might have a mold issue. And that was funny, (Sounds stupid but I know what I meant).

Yep the New growth being abit faded is completely normal when entering flower
