Cannabis sativa from the looks of it 🤭. Plant looks fine. It's in flowering and using up nutrients. Be sure to water properly and give enough potassium and phosphorus.

Guys what’s the opinion on flawless finish for flushing. I have read on many forum sites that it does not do anything does anyone have any experience with such a solution. I have used it for the first week to flush the plants and I will use it for two days of the second week.

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.

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

Hojas bajas amarillas
Tras un día de sol sin un calor excesivo he detectado hojas amarillas en la parte baja de esta auto mutante (2 plantas de una semilla). La he alimentado con algunos ferilizantes, incluso calmag en una cantidad adecuada para la prevención... ¿Qué podría significar? ¿Como parece?

First grow, calcium deficiency?
First grow, help please. As seen on the pictures provided, the leaves are getting brown spots on them with some kind of yellowing. I also do have some yellowing tips. I do suspect a calcium def. after some reading but would highly appreciate the input of a more experienced grower
