Ph value is decreasing despite BioBizzUp

I don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2. Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil. Additional question for SD: What to do with the brown leafes? Remove them?

250 liters pot , better dont flush ;) How you measure ph of out ? Do you take middle of eun off, do you collect it on clean new plate/sourcer ???? There is organic or simple ways to put ph up, like lime. But i wont recommend it in soil. Just have small run off ( which is complicated in your case ) have good wet dry cycle - what is hard again and load RIGHT ph when you water. Soil should buffer herself.

Hello! Am I reading your diary correct? You have 60+gallon of soil but are adding ph up via a liter of water from a spray bottle? I think the expectation that this process will change the Ph of your 60+ gallon of soil is just unreasonable. I would suggest setting the ph of your water and totally saturate the soil during the next watering. Dead leaves you can remove. Dead material attracts things you don't want on your plant.

Also, 4ml & 10ml of nutrients. WAY TOO MUCH.. Lower your nutrients. + dolomite lime takes weeks to take affect. Not ideal adding it like that. You go by ppm. Not ml/l.

You're measuring run off? With soil you need a ph stick. You can't tesr soil run off. It'll nvr give you the correct ph. As the soil filters out the nutrients, what you get out the end is waste water. Really u shouldn't be getting any run-off with soil imo.

High weefi, The reason is really simple. Your plant does use more water then nutrients and because the nutrients are acidic, the pH drops. The reason for your deficiency is indeed due the low pH value. You need to give less nutrients if you want the pH value to increase to the right value. You can start with 25% less nutrients and measure howmuch the pH will increase. Happy Growing Buddy! 💚

Iv looked at your diary, looks like your medium may have been outa the required ph value for a short while. Next watering in your schedule put through double the amount of water with no nutes and have your water around a ph of 7.0, hopefully that will remove any salt build ups and reset your medium closer to ph 6.0. Looks like you needed a bit of calcium a few weeks back. As for dead leaves, if they are dead then remove them, if they have life left in them then leave them alone. Good luck.

SD Question: Pictures would be very helpful, as well as further info like how old the plant is and which stage it's in. Without that it's difficult to make an assessment. Ph value: That could be due to several things including, which type of soil you are using. Coco can absorb nutrients and retain them thus influeincing the measurements of your runoff. Would definitely need more info here.
