No debes preocuparte para nada, las lineas moradas pueden salir hasta por un leve estrés en la planta, si no ves otro síntoma debes sentirte feliz por tu trabajo! Buenos humos! 👌

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

Small leaves, purple leaf stem and veins. Newer growth drooping
Second time this is happening. Plant grows beautifully until it starts to flower and then I get purple leaf stem and veins, small leaves and grow slows down. Exactly the same issue I had with my bubba kush. What's the problem ladies and gentlemen ? Temp day 25 humidity 45-50 %.

Calcium deficiency or overfed?
Hi. This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress. Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain. Thanks!

Calcium Deficiency???
So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!
