Here's coco 1.1/1.2ec (600ppm) a+b only.

It's entirely up to you but I wouldn't be using any big bud ever, it's not needed if you're using any reputable nutrient brand.

You'll naturally be reluctant to use less I can understand that but I can assure you that you'll see the back of the problem getting your nutrient strength in check, it's too strong.

I was just feeding at 5.8 to 6.0 the whole time. But like I said, they started yellowing on the top leaves right around week 3 to 4, which is when Big Bud starts. That’s why I checked the runoff, I thought maybe it was nutrient buildup. But the PPM is only around 1400 and I feed at about 1500. But like I said, I noticed the ph almost at 7. I’m trying to figure out why the yellowing and to stop it and hopefully turn it around. I had the same issue last run but I never checked the runoff and eventually the buds stopped growing and yield suffered.

My man....thats WAAAY too much ppm for any stage...my max is 1200 at late flowering stage. The most I've ever pushed is 1250 and that was pushing it, and in late flower stage. Just slow it down brother and cut it down to at least 8-900 ppm and build from there
