7 days ago someone here helped me to notice a nitrogen toxicity presence due to dark green leaves. The same day (7 days ago) the soil was flushed with 10 L of plain water with 6,5 PH. After one week flushed again with 20 L of plain water with 6,5 PH. Any advices?

Hi buddy, first of all amazing grow so far :) Flushing your plants after observing nitrogen toxicity was a good step to help correct the issue. Here's what you can do next: 1. Monitor Plant Response: After flushing, closely observe your plants for any improvements in their overall health and leaf color. Nitrogen toxicity symptoms should start to subside as excess nitrogen is leached from the soil. 2. Check Runoff: When you watered with plain water, did you measure the pH and EC (electrical conductivity) of the runoff? This can give you an idea of the nutrient levels in the soil. 3. Nutrient Adjustment: After flushing, you might need to adjust your feeding regimen. Gradually reintroduce a balanced nutrient solution with a lower nitrogen concentration. Monitor your plants' response and adjust nutrient strength as needed. 4. pH Monitoring: Continue to monitor the pH of the soil and runoff. Maintaining the proper pH range (around 6.0-6.5 for soil) helps ensure nutrient availability and prevents nutrient lockout. 5. Recovery Time: It might take some time for your plants to fully recover from the nitrogen toxicity. Be patient and give them the opportunity to bounce back. New growth should appear healthier. 6. Leaf Trimming: If you have severely affected leaves, you can consider gently removing them. This helps the plant direct its energy towards new growth. 7. Avoid Overreacting: While you've taken appropriate steps to address the issue, avoid overreacting and making sudden changes. Gradual adjustments are generally more beneficial for the plants. 8. Regular Care: Continue providing proper care in terms of lighting, humidity, and watering practices. Healthy plants are better equipped to recover. 9. Observation: Keep an eye on your plants daily. If you notice any new symptoms or changes, adjust your approach accordingly. Remember that recovery from nitrogen toxicity takes time, and the plants might not show immediate results. Continue to provide a balanced environment and nutrient regimen, and your plants should gradually improve. If you have any further questions feel free to drop me a DM :) Good luck and all the best

LOL ... N is important in flower... DNA requires it.. every single cell that reproduces needs N. it's insane people think that the flower needs little to no N i flower... stop perpetuation nonsense. it's wrong. you might need a 10% less, if that... i do get slight buildup over 6-7 weeks after flip, but the fact it takes so long to see a buildup means it's mostly being used at the same rate, just slightly slower. the plant absolutely needs N at nearly as high of levels as it did in vege. flushing will fix the substrate.. it will not remove nutrients from teh plant. A plant cannot do such a thing. it has no waste excretion. all you can do is give less N and the plant will suck down what's overstocked in the leaves, then you have to start giving the right amount or you end up with a deficiency. this is all about rate of use vs rate of provision. you see toxicities and deficiencies when these rates don't match. the close you are, the longer it takes to see a symptom. *** some exceptions - Mg takes 5-6 weeks after the problem starts before you see a sympto. Mulder's chart is another layer of sophistication to understand in regard to feeding a plant. the indivudual nutrients molecules have relativistic realtionshipis with each other. Add more of "this" and you need to add ore of "that" to match or you run into an issue. Possibly add too much of "this" and you lock out "that" ... google mulder's chart. it's real science.. not peanut gallery nonsense.... made up based on a few plants grown in a garage or basement... no control group.. no understanding of the scientific method.. no verification.. yet, super confident about the nonsense.

When you feed just give a quarter dose of what you were giving in the nitrogen feed. Your plant mainly wants potassium and phosphorus right now in flowering. Nitrogen is used very little in bulking. If anything it can hinder bud development.

If you already flushed the medium and adjusted the feeds then that's all you can do. The plant will use up some of the excess stored nitrogen but some of the damage is already done and theirs nothing else you can do. Keep the feeds in check and it will normalize its self in time. Colour of the water does not determine much other then pigments coming out of things. Good Luck!

Hi, for now I would monitor the plant regularly to see how it will react. Be careful for other nutrient deficiencies that might show up due to the flush removing all water soluble nutrients. Good luck with the rest of your grow, keep and close eye and you should be fine.
