Bam! Fully diagnosed, problem solved, and with only 28 words and a bunk picture to draw your conclusion, your the man! How'd you do it?

What kind of water are you using. You might also need some calmag.

like i said cant see from pic. If im wrong ill be the first to admit that. now that being said. He said always happens(and in the 3 wk of flower), and the nutes he is using is 4/2/2 N/P/K. as its normal for fan leaves to yellow in late flower because they use up the N in the leaves. So from what he said its a 75% chance its N IMO.

Im using tap water that has been sitting for 48 hours. My water is actually really clean, it comes out the tap at around 100 ppm
