Grow QuestionsWhy do leaves turn yellow and die

Why do leaves turn yellow and die

DonCostrostarted grow question 3 years ago

Does this look like underwatering, heat stress, or any kind of defficiency? Also might be rootbound, cause I used not a lot of soil which also makes water evaporate faster. I water 0,8L/2 days pH=6.3=runoff, If its hot some leaves start to droop in less than 48h after watering.

Bro, vi tu diario y usas Biobizz, yo tambien jaja! xD Tus niñas están hermosas. Nada que de preocuparse tanto. Buen trabajo!!! Yo creo que es porque estas usando 3ml/L de Bio-grow en la cuarta semana de floración, normalmente el consumo de nitrógeno baja a medida que avanza la floración. Si mides los ppm del agua de la escorrentía probablemente encontraremos valores altos, y a las bebes no les gusta el suelo con mucha carga mineral. A veces cuando eso pasa ocurre un bloqueo y deficiencia de algún nutriente. Te recomiendo empezar a bajar la dosis de Bio-grow con eso mejoras ppm del suelo. Medir ppm agua escorrentía y de riego. Ví punta de hojas quemadas y puntas de hojas parcialmente curvadas. Buenos humos! 💪

Update: I checked ec of the runoff and it was abt 4000😵, @WML, very good guess sir👏. I did not have TDS meter, only got one just now and glad I did, so I can be sure how to proceed now. Much thanks for your answer.👊

I think its because the leaves are so shaded she is naturally defoliating herself putting the stored nutrients to better use. Otherwise it looks like a nitrogen deficiency. I'm not seeing any stress( usually comes in the form of the serrated edges curling ).

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.

I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail.

Lower leafs getting yellow tips and spots I just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake. They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.

Yellowing leaves Lower leaves are turning yellow, these seem to be one that are hidden a bit from sight, so possibly not getting enough light, but it seems to be spreading, and one of them has fallen off. Is this some form of nutrient difficiency, or something simipler?
