I believe this is the first sign of burning from feeding with a cannabis incompatible fertilizer with a strength of 18/18/18, which is waaay too strong in every macro nutrient. For veg you want fertilizers (roughly) around 5/2/5 and for flowering (roughly) around 4/4/6.

Deiner Pflanze fehlt Magnesium! Füge deiner Nährstofflösung etwas calmag hinzu und es wird sich besser. Ich hattee dieses Problem häufig, da wir sehr "weiches" Leitungswasser in meiner Gegend haben. Bei Umkehrosmosewasser ist das auch ein häufiges Problem.

Leaf discolouration. Nutrient deficiency?Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Organic peat control I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Burnt, should I throw it and start from zero?I have 1 burn auto for excessive light, should I throw this one and start from seed again or maybe flipping to 12/12? The light is farther now but maybe I can do something else than put away my lights.. my current schedule is 18/6 and the plant is around 45-50 days old

¿Qué le ocurre? ¿Tiene recuperación?Las California Kush no acaban de recuperarse. He regulado el pH y la EC de todas las plantas. Una parece que se recupera y está echando hojitas pequeñas de un color sano, pero a la otra le salen muchas manchas en las hojas nuevas.

PH Fluctuations and/or Nutrient Issues?I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?
