Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?
tiny_couchstarted grow question 4 years ago
Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

That level of feed for bio Bizz is spot on, I am almost 100% that’s only a magnesium problem. I add about 0.75 to 1ml per lite cal mag and you will be flying again in no time.

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky whiteBuds. Other

The stems began to turn red. Yesterday it was less, but today it is more saturated and spreads to the veins of the leaves.

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.a year ago
