I’m seeing some yellowing on a few leaves I’m wondering if it’s from when my ph was a little high or something else does it need more of something potassium cal mag??

You’re flowering, and at 1/4 strength nutes? I’d say she’s under fed.

It just stared flowering going in it was 1900 runoff was bout 1700 didn’t want to overdo this one my first grow went a little hard on the nutes and git a lot of nute burn

Should I up the flower nutes my next watering but come off the nitrogen a little maybe go up to half strength

1700 ppm or ec? I defiently learned this time that before feeding again let those ppms drop to around 300. Im using fox farm right now also with happy frog.

Thats my purple punch feeding at 600 ppm. 2nd week of flower.
