What’s up with these girls?

Day 23
First: White Widow Auto by MSNL
Second: Gelato Auto by female seeds
Nutrients: Humbolt Countries Own starter pack
Medium: Coco
Was watering with 5 to 5.5 then realized that was to low so I started watering with 5.8 to 6.2 ( this is where I think my problem happend but I’m not sure)

Whats the issue?

There’s a pale green / yellow color between the leaves and some are starting to claw a bit

They look pretty healthy to me. Trying to do better might end up causing more problems.
