I'm entering week 7, what's happening?

Spiritual_Herbstarted grow question 4h ago

I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

What could it be?I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

drooping leaves, cold weather and high humidity, is it overwater problem?I think i´ve overwatered my plants, so it´s is cold (16 C / 60 F) and relative humidity around 70%-75% . old leaves are turning yellow. I´ve lowered the water frequency and wait the soil to dry before water again but leaves are still droopy. What do you think? is it overwater?

orange sherbet crispy leaves. Close to harvest Fastbuds Orange sherbet first grow. I already harvested this plant but I’m curious what the issue was. The leaves were yellow and crispy to the touch. Other leaves looked fine. 2.5oz harvest but it dried really fast(7 days) and now smokes harsh. Don’t want to repeat this mistake.

I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?
