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

[KingShug007]

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!

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

 

[KingShug007]

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

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
