¿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.

Lila Stängel - Nährstoffmangel?
Hallo zusammen, ungefähr eine Woche, nachdem die Pflanze mit der Blüte begonnen haben, haben sich die Stängel der Blätter rötlich/lila verfärbt. Meint ihr das kommt von der Genetik (Auto Overdose - Divine Seeds) oder könnte es sich auch um einen Nährstoffmangel handeln?

Deficiency or leaves turning red/purple due to flowering?
Deficiency or natural change due to flowering? I fed her additional CalMag and PK so I slightly caused nutrient burn. That does not indicate a deficiency normally. Thank You for any advice!

Gelbe Blätter, mit Lila Flecken
Meine Pflanze hatte Nährstoffbrand, dann hab ich erstmal keinen Dünger mehr gegeben. Jetzt bekommt die Pflanze gelbe Blätter mit leicht Lila flecken. Nährstoff mangel? Oder Blattverfärbung durch Blüte? Oder immer noch Überdüngung? Ich verwende BioBizz Starterpack.

Have a look at my leaves that have turned yellow and red. I've search online and can't seem to find a similar picture. Is this normal due to late flowering in some plants? Is this a nute problem? If I add the needed nutes, will this clear up? What's going on?

The leaves are yellowing, some are turning purple.
The leaves are yellowing, some are turning purple, maybe it's normal or maybe not, I don't know. If anyone could give me some suggestions. I decreased the light intensity to 75% because unfortunately I can't raise the lighthouse.

dying top fan leaves
All of my 3 plants are receiving the same treatment but one of them is showing signs of distress. Some of the top fan leaves are getting dry and brittle and dying. I thought perhaps the problem is I haven't been allowing enough run off?
