Can’t get pH down in coco

[bk78]

Well on a positive note

at least this new guy hasn’t told us all to fuck off yet, and that we don’t know what we’re talking about.

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.

Fed A&B with a PK boost at week 6 for the full week, then back to just A&B

Those plants don't look happy. Mix your nutrients to 800 ppm, pH, and feed. Don't bother looking at the runoff or do anything to change it. In coco all you have to do is take care of what goes in.

And ditch those crappy FF nutrients.

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

What strain? Absolutely gorgeous . Well done

wonder why the leaves are yellow. Ye gods 1500

My plants in coco dtw are generally happy at 1.3 EC from 1-week rooted clone thru harvest.

Alright I will flush and reduce the ppm. Thanks for the insight everyone, much appreciated.

Do not flush with plain water.........weak nute solution.

^^ this, you need an osmotic gradient to leach retained salts in your medium, 250 to 300 is about right.
