Master Kush turning yellow

[brickmanz]

My grow is about a month old. All was going fine till my master kush strain started turning yellow with brown spots.

I'm using fox farm nutes. Just added some calmag two days ago.
Ph- 5.5-6
Ppm is around 120.

Looks like a Ca/Mag deficiency...I'd wait a little longer since you just gave it the dose of Cal mag. You could also foliar spray with a little Epsom's salt @ half teaspoon per gallon or so. Can also feed that same ratio to the roots to help green her up. But always keep in mind that less is more with our favorite little green plants! Especially when it comes to watering and nutrients. Just try to get her to the finish line with as little stress as possible. Keep up the good work...It'll all pay off in the end!

This is only my second grow. I did a ton of research on hydroponics before my first one. I'm still having trouble getting my nutes right. It's a little strange how my bubblicious didn't turn yellow too. They are a little less mature than the kush
