continuing nute burn or deficiency now? biobizz lightmix +organic nutes | runoffs EC 1.8-2.5 | PH 6.3 | DLI 45

Everything you're feeding is organic. What does that mean? It's not readily taken up until microorganisms break it down into smaller pieces. Why does that matter? Generally takes two to six weeks for the organic matter to be fully broken down in the soil and become available to plants. Feeding organic nitrogen 3 weeks into flower is not helping, plant doesn't want any more nitrogen, skewing your ph Nitrification is the process by which plants convert organic nitrogen firstly into NH4+, then process that into NO3-, Different forms, different charges, different ph. At a pH of 6.2, nitric acid is about 20% as efficient as it would be at 7.0. Everything you have ever fed has been organic, your running pH of 6.2, CEC of the soil is full, microorganisms just continue to break down organic nitrogen into the soil, skewing the ratio of PH dramatically. Your EC within the medium is full, as the plant uses less and less more and more will remain in the soil. This will turn your medium acidic. When ammoniacal nitrogen exceeds 20% if the total nitrogen, it can lead to various detrimental effects, including inhibited growth, reduced photosynthesis, and potential tissue damage. Excessive ammonium can disrupt nutrient uptake, particularly calcium, and lead to an imbalance in carbon and nitrogen metabolism. Different forms of nitrogen have varying degrees of mobility within the soil. Nitrate (NO₃⁻) is highly mobile and easily leached, while ammonium (NH₄⁺) is less mobile due to its attraction to negatively charged soil particles. This difference in mobility affects how easily these forms of nitrogen are taken up by plant roots and how susceptible they are to loss from the soil through leeching.

Flush your plant and give It a dry out period and the only water For a week. Your plants are doing fine

Don't flush, no need. Potassium, magnesium and calcium deficiencies........resume feeding.

Hey there, last time (12d agos) most comments on your question pointed towards a slight burn. Even if it looks worse now. :-( I saw you are using biobizz soil and nutrition your flush was 2d ago. First of all, that is not very much time for the plants to recover. Moreover, if it was your first flush after the question 12d agos, it's rather late. Never used Biobizz soils, but they advertise "bio" and stuff.. so it's more or less a living soil?! IDK how much a flush of that specific product is really effective or not (it's no coco😅). The living stuff in your soil happily breaks down whats left anyway - I would suggest. IMO still - high on nutrition like 12d agos. Of course some excess and deficiencies can be confused. Regarding the light mix and "bio" nutritions, in general I'd also suspect a deficiency (s. BC_green). To be sure, you have most control and knowledge about your grow. Take a chart and check your plants. Especially, is it located at new / old leafes and top / bottom will give you more hints and a greater possibility to hit the right spot (if it's not the excess!) 😅 Best of luck. I hope they will be in perfect shape soon 😜 (just one of the first google charts I found - search one you can handle perhaps photographic pictures are better? or not?😅) https://dutch-passion.com/img/cms/Blogs/cannabis-nutrient-deficiencies-and-excesses-chart.jpg

Nutrient issues can be a little hard to pin down because one can impact the other, this article explains why: https://www.gardenmyths.com/can-leaves-identify-nutrient-deficiencies/ That being said, my best guess from looking at your diary is lack of potassium (I am intentionally feeding low potassium fertilizer blend for flowering on an auto as an experiment on boosting cannabinoids) and you can look at those pictures here if you're curious: growdiaries.com/diaries/268341-grow-journal-by-bc-green Growing both plants in one container ends up making the two compete for resources and it can be difficult to then predict nutrient demand. I would definitely resume nutrients, especially if the issue looks worse after flushing. I would stick with the regular feeding schedule to the end. They are getting close enough and the plants look healthy enough that you should still have a very enjoyable harvest. Hope this helps and happy growing!
