Con el amarillamiento de las inferiores, tambien podria ser falta de N. Revisa el PH que no sea que te bloquee alguno de ellos.

¿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.

Weird burn
Thought I had a calcium deficiency but now I’m not so sure. Could have got a bit too much direct sun out of the tent. Any ideas on this ?

What do these yellow markings on the leave tips mean?
What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps

Is this Nute burn?
Is this Nute burn or something else? Using bio bizz grow, bloom and top max with “all in one” soil. I’ve recently upped the nutes in line with the bio bizz feeding schedule for my soil but it looks like the plant is freaking out at something. Thanks guys

Can't deal with yellowing leaves in 4th week of flowering
Been having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?
