Deficiency Week 5/6 Flower
Sciolistic_Steveanswered grow question a year ago
the red is senescence or colder night time temps... nothing to worry about.. aslo could be genetics. if temps drop below 68F it can exaggerate this coloration.
if it's not moving up from bottom, it's possibly k-deficiency. but usually this would be more damage on the leaf tips. if it is moving up from bottom, it's N.
seems a bit limited.. 2 bad looking leaves but the rest is small potato damage. verify pH but this doesn'tlook like a pH issue. make sure calcium is not too high as that can lock out K.
can always use manic botanix nutrient ppm calculator to track individual ppm of each nutrient. over time you can learn what is too high or too low with high precision.

I would say from experience that this is a ph issue in substrate causing a lock out. Your plant is showing a few deficiency signs at once is what brings me to this conclusion. Also common in flowering since the plants tend to absorb lots of potassium, and phosphorus in this time. The phosphorus being absorbed controls the ph. So if the feed is toobstong or nor strong enough it will throw the ph out of mine fast. Would be my answer from years of experience. 🌱👍🏻

Give it some calmag and make sure the pH is what it's supposed to be. She's looking fine.

Hallo ich gehe eher von einem Phosphor Mangel aus.
Wenn du jemals trockene Blätter mit braunen Verfärbungen gesehen hast, dann hast du vielleicht selbst schon einmal Phosphormangel gesehen. Er kann auch rot/violette Zusammenballungen (oder tote Punkte) in den Blattstielen verursachen. Die Blätter können in der Folge einen dunkelblau/grünen Farbton annehmen.

Hojas bajas amarillasTras un día de sol sin un calor excesivo he detectado hojas amarillas en la parte baja de esta auto mutante (2 plantas de una semilla). La he alimentado con algunos ferilizantes, incluso calmag en una cantidad adecuada para la prevención... ¿Qué podría significar? ¿Como parece?

What can I do? Leafs starting to turn yellow. First growerYesterday, I noticed some leafs starting to turn yellow and also the tips of the top leafs to be a bit brown. So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?

Living soil and rain water problemHas using rain water killed my living soil?
Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients.
So basically is my living soil now just soil or is the microbial life still there?

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.

Nitrogen deficiency but why?My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.

Yellow lower leavesHello,
This is my first grow and now I'm confronted with the first problem.
The lower leaves on my plants are turning bright and yellow. A few leaves have very small brown spots. Can someone help me and perhaps have an idea as to how I should proceed? Thanks.

Deficiency because she starts to flower? Leaf tipps light green. Some purple at the stems.I have not fed her, just a bit here and there. So I do believe she starts to need her medication.
Its going to the end of preflower week1.
Symptoms: some light tipps and some purple at the stems.
Solution: feed her P and K. could add some CalMag ?
Or Still feed more NPK?
