Need help GSC?

I have a girl scout cookie and something is wrong with the leaves at first when it was vegging the leaves looks like it's fake leaves and now there's some kind of deficiency.

Are they in veg still?
Are you suing nutes, if so how much?
Have you check your PH?
How tall is it?
How often do you water/feed her?

No it's flowering week 3 or 4. I'm feeding Floranova Bloom,Floralicious plus and Koolbloom liquid once a week at first I was feeding twice a week then back it up to once a week and every 2 weeks I feed Alaska morbloom and molasses once a week. I check my PH an it's always low so I add PH up to 6.3 to 6.5 but the last feed I didn't check my PH. Even with correct PH I still have this problem on this plant only and the other different strain plants don't have this problem. It's been like this since while in veg and I just thought it would go away since I give all my plants some calmag and plus floranova bloom already have calmag in it. I water my plants everyday since it's so hot mostly over 100 degrees but it's getting cooler.
