Possible overfeeding. Should I flush?

It's possible that you may be overfeeding your Quick One auto-flowering plant, especially if you've been following the feeding schedule intended for photoperiod plants. Auto-flowering strains typically have shorter life cycles and may have different nutrient requirements compared to photoperiod plants. Here's what you can do to address the issue: Flush the Medium: Consider flushing your growing medium with pH-balanced water to remove excess nutrients and salts that may have accumulated. Flushing can help reset the nutrient levels in the soil or coco coir and alleviate stress on the plant. Adjust Nutrient Strength: Reduce the strength of your nutrient solution by diluting it with water. Start with a lower concentration than what's recommended on the feeding schedule and gradually increase it as needed based on the plant's response. Monitor pH Levels: Check the pH of your nutrient solution and ensure that it falls within the optimal range for cannabis cultivation in coco coir (around 5.5 to 6.5). Fluctuations in pH can affect nutrient availability and uptake, leading to nutrient deficiencies or toxicities. Observe Plant Health: Keep a close eye on your plant for any signs of nutrient burn, nutrient deficiencies, or other stress-related symptoms. Darkening of leaves could indeed indicate nutrient excess or other issues, so monitoring the overall health of the plant is crucial. Consider Light Intensity: While it's less likely that LED lights would cause nutrient burn compared to high-intensity lights like HPS, excessive light intensity can still stress the plant. Ensure that your LED lights are positioned at the appropriate distance from the canopy to prevent light stress. Patience and Observation: After making adjustments, give your plant some time to respond. It may take a few days to see improvements in its growth and health. Continuously monitor the plant for any changes and adjust your approach as needed. By taking these steps, you can help alleviate any nutrient-related stress on your Quick One auto-flowering plant and promote healthy growth and bud development. Remember that every plant is unique, so it's essential to pay close attention to its specific needs and adjust your care accordingly.

Just reduce the fertilizers to half to three quarters strength as what you have been giving.......no need to flush or do anything drastic.

Esta usando un ph de 5.8 en el riego, este nivel de ph permite a la planta mayor absorción de nitrógeno y menos de potasio. Puede aumentar algunos puntos del ph de su riego para que el potasio esté mas disponible. Puede usar un ph entre 6 y 6.2. No hay sobrealimentacion lo que está pasando es que el potasio que necesita sus cogollos no está disponible. También como mencionaron en diferentes respuestas,puede bajar el nivel de nitrógeno y reemplazarlo por más potasio.

Possibly to much nitrogen, your giving 3ml/L of a calmag product, if thats the recomended dose then fine but I haven't seen a calmag product say give that much, quite a lot of calmag products contain nitrogen so you may be over doing it.

Looks like a slight bit to much nitrogen but not at the point where you should worry about it. I would change up the amount of nitrogen you are feeding though. In flower you really do not need a whole bunch of nitrogen. N-P-K in flower usually follows 1-2-3 ratio so you would want to switch to a bloom fertilizer that has those ratios or you can adjust your fertilizer in your water mix to meet that by using some sort of PK boost. You can do this by using roughly 1/2 of your recommended grow and then half of a PK boost. (This is rough estimate but it all depends on what products you are using) the end goal is to have lower N and higher P-K. Hope this helps.

No need to flush, its just border line N tox, nothing to worry about, do as others said and cut back the N a bit. Plants still need N in flower just not as much. Eg, if your giving a feed that's 4-4-4 in veg maybe alter that back to 2.5-5-8 or something like it in terms of NPK content. Good Luck!

It looks fine. 42 days is only six weeks and with four of them for veg she is only week two or three of flower. You can back off a bit if she looks dark but you will know when you over feed as the leaf tips will burn. As you are entering the bloom stage now you will slowly want to reduce nitrogen and increase phosphorus and potassium. The N is what will be making her look dark. Follow your schedule but you want to be introducing your ok boost and reducing the base soon.

Cut back on nitrogen. You are going into flowering and your npk ratio is 1-2-3 for flowering. So the nitrogen controls the shade of green in your plant. Dark green is too much. The potassium and phosphorus is what will make your colas.
