they could just be the strain has purple in it, if you had a cal/mag going on it would be a lot different, there would be a bronish color and spotted kind of, do a google search on cannabis deficiencies and look at the pictures, i would check it out and see for yourself

Problema con mi Runtz MuffinBuenos días,
Tengo un problema con mis hojas, (puse fotos para que podáis ver).
He visto que podía ser un deficiente de fósforo. Pero también puede ser un problema de calcio y de magnesio.
Alguno podría ayudarme con eso ? Que tengo que hacer ? Añadirle un PK 13-14 ?

Brown spots on leaves! To Flush or not to Flush? That is the Question.Hello,
Seeing lots of brown spots developing around middle tier leaves. Reddit is telling me I should flush with 15 gallons of water to get rid of salts around the roots. That seems extreme but if that’s the cure I’d like to know more and can I use my tap water (7.1pH 133ppm)?

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Purple stems-curling tips leaves point downGuys the sides stems seem really purple!even the central stem..
Why? magnesium deficiency?or genetics?
And that leaves tip pointed down; they are a problem..
Maybe N deficiency?(due the early preflowering for the wrong light cycle) Thanks :)

Possible overfeeding nutes?Could someone possibly identify the issue on that one leaf? I had another like that a bit worse that where the edges started to curl. They were fan leaves so I ended up removing them as they were a bit worse off. Doing much better now, only guess is too much nutes.
