4 weeks in veg, leafes starting to yellow HELP! Plz

started in soil in solo cups, then transferred to coco, perlite mix in 5 gal pots. Using ff cultivation nation part 3 trio and cal mag. 3 ts1000w mars hydro lights, I realize the yellowing is mild, but used to green at this point. Any ideas will be appreciated, thank you!

Ph is right, ppm is right, temp 75 day, 68 night 50% humidity

What do you consider right as far as ph and ppm?

6.5 for coco ph. And when I feed about 900 ppm. I've been using about half nutrients thats suggested for my nutrients.

Ph is wrong. Coco should be 5.7 to 6 no higher

ph about 5.7 im using in coco

Awesome thank u will make adjustments and see what happens. What do u ppm when u feed coco? I've been using nutrients 3days in a row, then flush.

I feed every day, ppm around 1350, I have slowly lowered it too 1000 over the last 2 weeks because of some tip burn though the buds are growing well, my latest grow is at 5 weeks flower.
See what happens
