Leaves dying

Thank you to the both of you. I learnt a lot asking for this. See you around gentlemen !

Hello roberts, thanks for your response. I'll do that. Do you mean that terra bloom from plagron is not optimal ratio wise which is (if I understood your scale) 1-1,5-6,9 ? growdiaries.com/nutrients/plagron/terra-bloom

You have not been getting proper run off to wash out old used nutrition. So in your soil you have a build up of salts. You need to flush that out , and replace with new nutrition. This causes burns as you see , and will cause major ph issues in soil as well. Flowering npk ratio is 1-2-3

Hey Organoman, True that infos are missing here. This is soil, ~23°C, always watering with a 6.5 pH. Nutrient wise I use plagron terra bloom. I only use half recommended dosage (2.5 ml/L) and always use plain water in between feeds. So yeah I may have fed too much but I'm lacking benchmarks as it really feels like I'm not overdoing it. I water every 2/3 days around 2L (3gal pots), so I feed em every 4 to 6 days I'd say. That's what I do since flowering and did not observe any other problem than that. Should I stop feeding and/or kind of flushing it to avoid anything worse ? Thank you for your time

Without a diary or much more information about what you have and haven't been doing, it is hard to say "change this" or "change that". At a rough guess, maybe feeding too much or too often? Soil, hydro, coco, DWC??? Nutrients? Dosages? Frequency? Temps? pH? etc, etc
