Runoff PH close to 8 - How to fix?

Those tabs are for active soil grows. They could be full of things like urea that will perform poorly in coco.....and holy sheet those things might be a new low in consumer gouging. 133GBP for 2000g of product. Hipster ganga nute companies never like transparency and will often make it difficult to find product info.

Just a personal opinion here, for the price of those tabs you can purchase an EC pen, pH pen and a proven soluble nutrient.
Can you dig those pucks out and switch to continuous fertigation?

This isn't even my first grow. My first grow was indoors in coco as well, I just forget stuff easily it seems, weed you know. My first grow was way more successful than this one. To be fair it wasn't auto.

Gotcha. Not going to overdo it, but the water does need a small adjustment, I think it's at 7.5 or so at the moment.
When you say "it's at 7.5" what is "it"? The substrate? You have to do a slurry test to be sure.

I paid 24GBP for 20 tabs + 500ml of the liquid solution, so not as bad as the site linked, but still.

I've switched to continuous fertigation with the provided liquid nutrients, but I get Advanced Nutrients in a few days. Going to give their PH-perfect line a go.

Do you think the single puck is doing much harm? I can try to find it. I fear the roots might have enveloped it!

Sorry, I should have been more clear. I've tested 3 things. Runoff, water, and water + fertilizer. I uploaded pictures in order. Runoff appeared to be in the 8+ area, water seems to be in the 7+ area, water + nutes seems to be around 7 or 7.5 as well. So everything seems to be higher than it should. Hopefully lowering water PH to 6 should even things out?

I will look into a slurry test

To be clear, that should be the water with the nutes. That said, I haven't used the pH perfect nutes so not sure how they measure. I have heard all good things about them though.
Yessir, gotcha. I did look up reviews and some videos and it seems like they do the job as advertised. People also say Advanced Nutrients is overpriced and that you don't need a majority of their products, just stick with the main three and you're good. Again, just what I've read.

It seems that EU hasn't woken up yet and many retailers are still pushing the bottle parade method of growing. Would be nice to see some of the dry fert distributors set up there. I can vouch for House & Garden Cocos A/B. It's a solid fertilizer for a start to finish grow. Prices for a liquid were reasonable in the 5L size jugs. General Hydroponics has solid EU distribution also.

Another tip, just to make things easy. . .. and this is specifically if you're using bottled nutrients;

Once you've made your final mix and pH'd it, pay attention to how many ml of each part of your feed you used, and how many ml or drops of ph adjuster. What I do: I make my mix and I always add .5ml of pH down, which always puts my feed at 6.3-6.4 I just repeat this process daily and I keep my pH meter stored in KCL, and use it maybe every other week instead of every friggin day, or I'll just bust it out if I see a weird plant issue and double-check that I haven't strayed from my recipe.

*oh and real quick, that goes for EC/PPM meters as well. ..my opinion, you should only use a PPM/EC meter to dial in your mix then just repeat that mix. You should only ever need to reuse the meter if you change your mix, or again if the plant shows some weird response. There's no real need to check your PPM/EC every single friggin day.

Will do. Seems like the three nutrients I will get, micro, bloom and grow, all require the same amount on a day to day basis, so that part is simple at least.

Do you guys all use PH meters? Aren't they annoying to recalibrate?

I use the Apera PH20, it's a piece of cake to calibrate, I do it once a month at least.

I grow like PopandSon and only really use it to set up a new feed schedule and then roll with it. I grow in buffered peat mix so I have a wider input range versus a coco grow.
