thanks for the answer!could be calcium deficiency. try giving the plant some fertilizer and see what happens.
I use biobizz light mix and my Ph is around 6 to 6.5. I read that 6.2 and above is the best absorption of calcium but I watered 90% of the time with Ph 6 to 6.3. The last time I watered with 6.5 or 6.6 Ph and that's what happened..What your pH exactly? What medium are you growing in? Looks like an issue with your pH...
my stems are really decent. My tap water is 7,6 and I use Ph down till I hit low 6. Should I just water with a Ph like 6,7-6.9? I really think the calcium is the problem cause I used 6 Ph most of the time..hmmmm......
How exactly does P and Ca help absorb K? P and Ca are cations, and P is an anion..... right?
By the looks of it, you need Ca. If your ph in the soil is 6.0-6.5 like you say, I would throw some fine gypsum on it and see how she reacts. 1 cup gypsum per yard of soil to start out with. That would be my advice.
Not sure how you did it, but every picture doesn't show stem color. If your stems are purple, then you are lacking P as well. If your stems are nice and green, your P is on point. Good luck.
well I thought about this too,because it has quite common symptoms. How can I checkAlso, what is your Mn levels like? Those brown spots can also be a Mn deficiency.
ok so, my plants is an autoflower and she is 4 weeks old. I used only water for the first 3 weeks and from then I have added only once biobizz series and silicon. That's all. Ah and the strain is royal auto ak from rq seedsCa is very available in soil from a ph of 6.2-6.8. IME, Ca is always short in peoples soil unless they pay special attention to it. What have you been doing to make sure Ca levels are up? What have you added since planting? If the answer is not much, or cal mag, then Ca is the problem imo.
I will adjust Ph and nutrients and ill post again if the problem remains. Thanks for help.I always keep my pH between 6.5 - 6.8 in soil.
