If you use training methods like LST or defoliation, you may notice the exposed stems of your plants turning red, pink, or purple over time. This is completely normal and shouldn’t be cause for concern as long as your lights are sufficiently distanced and your plants look otherwise healthy.

фиолетовый стебель листа говорит о легком дефиците фосфора! дефицит мог произойти из-за: 1. некорректного ph субстрата. 2. слишком мало добавки bloom. 3. слишком много азота (добавки grow). Решение: 1. установить ph почвы в значении 6.3ph 2. уменьшить добавку grow до 0.4ml/l 3. увеличь добавку bloom до 2-2.5ml/l ✋😇👌 Удачи, бро!

It's like a little sunburn on your girl.. It's like what would happen if you were out in the sun for too long. It's a defensive mechanism. And nothing to be alarmed over! Happy growing! 👊

Lila Stil und Hängende Blätter Hätte da ein paar Fragen die Ihr mir hoffentlich beantworten könnt, liegt die Verfärbung des Stils an der kälteren Temperatur in der Nacht? Hängen die Blätter schlapp nach unten bedeutet das zu viel oder zu wenig Wasser?

Stems becoming red. I didn't use any nutrients yet. Should I add a little bit of them to water? Water pH is about 6.5. Do the leaves look ok?Looks like stems becoming a little bit red.. I've checked other diaries with this strain and didn't found anything like that. Before transplantation I have completely flushed my soil about 2 times because I found a lot of springtails in. Hope I didn't got rid of all nutrients..

Is it nutrients? Light?What can this be? The stem is red, and I thought it could be over lighting (I had 2 LEDs of 200 W each), so I removed one of it. But now I am also wondering that it can be nutrients, no? If so, how can I solve it? Let me know what you think. It's an autoflower - 7 weeek.

I think I have nut issues?OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?
