Deficiency Week 5/6 Flower
Sciolistic_Steveanswered grow question 2 years 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.

Many of my plant's fan leaves, especially lower down in the plant are turning yellow. Is this normal? I think I'm on my last couple of weeks for flowering, so I'm not sure if it's just part of the process towards the end. Should I remove them, or just leave them there?Leaves. Color - Yellow

I have the light at a height of about 40 cm. The photo is taken immediately after watering. The water drains as it should. I use biobiz lite mix. I think it will be poor water quality or spoiled fertilizer.
How do you recognize spoiled fertilizer?Week 1

leaf yellowingI have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.
