Veins yellowing, runoff PH suddenly quite low (5.2) with a high EC of 2.0, plant is close to harvest

Yeh he been running 5.7- 5.8 so plants won't uptake mag as easy as it would if ph was at 6.2 ish

Kinda funny, there's a lot to show these days that you don't need a super low pH in coco, but everywhere you look it's recommended lol

Anyone actually tested there coco pH with a proper soil ph pen? Would be interesting to compare to runoff ph

Never have, I imagine if you're using brick coco it will be the same pH as whatever solution you rinse with. Same for the pre mix stuff too really. And then it should be close to your feed until the salts start building up some. That's what is going to change the pH the most. I add flying skull z7 to minimize salt build up in the media and on equipment, it seems to help pretty good.

Seed/ripening phase pH in coco is 6.2-6.3. in veg phase 5.8-6pH is fine. if you give nutrients every watering, make sure you get enought runoff each time. Also keep your shit moist or even wet! Measuring pH in coco is not important and you dont really have to care about that, unless plant showing critical signs. More important is what is incoming water pH/Ec. If your Runoff Ec is higher than incomin Ec, you havent flush enought and this have caused buildups. Cheers.

Good grief stop arguing already

Mine are at exactly 2 weeks of flowering today. Everything looks good. All I did was adjust. I only checked mine because my autopot got knocked and leaked all over so I dumped it into a bucket and said screw it maybe I can dump it back in the Rez so I checked it and sure enough 5.2 so I just replaced the whole Rez.
