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.

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?

Yellowing, burnt tips and edgesHello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

Magnesium deficiency?I think I may have an early deficiency of magnesium? I'm totally guessing here. Not much experience. Seems to slowly be getting more pronounced.
First water since transplant to FFOF was only pure RO. Thinking maybe I should added cal-mag?

Wk 7: TDS readings 500-800pp, but 1 plant showing multiple types of leaf problems
I thought I fixed it, but now I don’t know what’s up or what to do? Thoughts?

What to do? Leaves are getting worse.Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?
