Since it is the oldest leaves and the newer ones appear to look OK, I'd say they are hungry. They need some nitrogen!

i was told i shouldn't give any nutes until i transplant and but under the 1000w. what is your opinion? this came from a credited grower but i need input she couldn't give me a positive answer on what is wrong.

i really want to hold off on the nutes just beacause my soil has everything it needs, so i checked the ph of the water i have been giving them and it was 7.8 or higher. could this be the problem?

Yea you want your ph to be around 6.3 for soil. during the veg cycle.And i got up to 6.5 for flower.So i would just say bring that ph down. But i think the range is something like 5.8 to 7.For soil
