AMNESIA HAZE AUTO FASTBUDS

bonjour des USA. j'ai déjà eu le même problème. 99% sûr que c'est le pH du sol qui est éteint. si vous vérifiez le ph de l'eau de ruissellement. l'eau qui sort du fond du pot lorsque vous arrosez, vous verrez que le pH est probablement inférieur à 5. si votre eau du robinet a un pH d'environ 7 à 9, je continuerais simplement à rincer le sol jusqu'à ce que le problème cesse. j'espère que cela aide. De plus, lorsque cela m'est arrivé, cela a commencé à se propager lentement à travers toute la plante le premier jour, puis après 2 ou 3 jours, c'était sur presque toute la plante et si elle se déplace rapidement, il y a de fortes chances que ce soit le même problème.

High Hix57, Stop giving the grow nutrient!!! Increase the bloom nutrient to 5 ml/L Increase Cal-Mag to 3 ml/L Decrease the seeweed to 2 ml/L pH around pH 5.8 Water till at least 30% runoff to prevent nutrient salts building up inside the coco!!! Happy Growing Buddy! 💚

N/P/K/Ca/Mg/S -- Nothing prevents you from having toxicity in one and a deficiency in another. All need to be in a 'happy-zone' relative to stage of life. Also, burnt tips can be caused by numerous things, even a S-deficiency. Looks like a potassium (K) deficiency. Possibly too much N, too - last picture is dark and a bit glossy. N inhibits K, so that could be part of it, but I think it's just exacerbating a shortage and is not the cause of all your visible k-def symptoms. you are in soilless, so this is a bit easier. Check ppms of what you give. I'd expect K to be 180, give or take. N at this stage probably 100ppm and possibly less. In the end the plant dictates. The individual nute ratios can impact each other, so having too much of one thing may require more of another to overcome the antagonistic relationship. But, if the overall formual isn't too esoteric, these numbers should be a good ballpark to make it a bit more of an educated guess than normal. pH somehere near 6 is fine. You go too low and you lockout Ca fairly quickly below 5.5 or so. 6.0 will not be the cause of any problem. My nutes automatically ph-balance to 6.0. 95-99% of plants pull off the same rez just fine and the 1-5% do well enough to not hand-water. Good formula = consitent results. Bad formulas can look great on a few plants and have problems with many others.
