Looks like potassium to me. Do not raise your nitrogen level in process. Your well fed there. Always be aware of run off ph and tds or ec.

Curling down shriveled leaves
Ideas on why these leaves are curling downward and seem almost "shriveled"?Soil has been wet/moist consistently and heat hasn't really gone above 78F. They are in ocean forest soil getting a suggested nute dosage can't imagine its deficient at this stage. Light or wind stress?

Gorilla Cookie Week 8
I will try to keep this short, but my Gorilla Cookie autoflower has some problems. The tips look like they are burnt or dying. I use living soil, so I didn't really give my plants any nutrients except worm humus a long time ago and BioBizz Top-Max yesterday 3ml/L. See my diary

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!

Crumpled new growth?
I've noticed that there are new leaves towards the base of the plant that are growing strangely. Could this be from low humidity? I've been having a hard time keeping it up. I also noticed that some of the leaves are clawing down (see week pics). Perhaps related? Haven't fed yet!

Help! Why are my leaves turning yellow?
Not sure why some of her leaves are yellowing on the edges. Is this due to environment? - 78.3°F | 64.8%RH Or a watering issue? - Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox). Or maybe a deficiency? - See Logs for complete details.

Leaf yellowing
Hi all. In the last 48 hours there has been a few lower leaves which have lightened in colour to a yellow. The whole leaf has changed at the same time so I’m not sure if this is an indication of an issue or if the leaves are being drained before the final ripening. Thanks 😊
