This was the same stage last run so yeah I think I'm way more prepared. Might be in for a new personal best, still got 50zips off the last run and it was crap for the most part. 67 is my best off my 3m² space

When you say the same stage, do mean they went downhill at this stage last time?

No I mean the photos were taken at the same stage, as in both taken at 28days of flower. Massive improvement between runs

OK I'm with you, I just had a look at the pics, the plants look good but like you say they're farther on this time around.
Isn't it great when it all comes together nicely!

Yeah they weren't bad but that was also about a week before I started getting nanners so didn't swell up too well. The stacking seems to be way better and I assume this lot won't herm being from seed and not 10th generation clones hahahah so the swelling should be even better. My goal is 100 zips, probably abit optimistic for the size of the room but we'll see hahah. I really appreciate all your time and advice mate the goat

Hey mate quick question with my ec. So my feed chart has been saying I should feed at 2.0 but have been feeding at around 1.3 like you said (which is great) but the chart says I should drop to 1.2 over the last 3 weeks but since I'm feeding at 1.3 already do I leave it or drop the equivalent I did over the first 6 weeks. Eg feed chart says 2.0 and feeding at 1.3 which is 65% of what it recommends, do I do that now too and feed at around 0.8ec (1.2 × 65%)?

Those plants look extremely happy with whatever is going on in the rootzone. I wouldn't worry too much about runoff readings. The only way to actually know what is going on in the rootzone is to catch the runoff of pure RO filtered water through the rootzone. If your measuring after a feeding, of course EC will be higher of runoff because your adding in fertilizer on top of what is being washed out.
In short, this explains why your readings would be higher, also your never going to get a 100% accurate reading because the coco itself binds to a lot of elements which won't allow them to be released into runoff to begin with.

"Nutrients absorbed by coco coir are released back to the root zone through a process called cation exchange. Coco coir has a high cation exchange capacity (CEC), which means it can attract and hold positively charged ions like calcium, magnesium, and potassium. When plant roots come into contact with the coco coir, they release hydrogen ions (H+) into the surrounding medium. These hydrogen ions displace the positively charged ions attached to the coco coir particles, effectively exchanging them for the hydrogen ions. As a result, the absorbed nutrients are released from the coco coir and become available for uptake by the plant roots. This process is ongoing and dynamic, allowing plants to access nutrients as needed for healthy growth.
