JoeNathanstarted grow question 6 months ago
My lady is turning yellow around the edges of the lower leaves others are dark green. I just did a top dressing less than a week ago I used feather meal kelp meal alfalfa meal and some bat quano. Looking at charts it seems to be a nitrogen deficiency. I know feather meal is slow

potassium deficiency, and if recent week of fertilization is similar to previous weeks, then i feel more confident about it based on weighted average npk values loosely calculated in head.

If those yellow leaf edges turn brown and get crispy then Potassium is your issue. If you are in CoCo Coir, it has an abundance of Potassium. But it can get tricky because excess calcium can lock out potassium. If adding more potassium doesn't halt the progression then it's time to flush and reset your medium.

I am wondering if my purple Auto, at 4 weeks, is doing well in termes of Cal/Mag (that I don't use) or NPK (normal use of Biogrow, bloom and top max) because I am having the points of the leaves getting yellow? 🤔🤔
Thanks :)

Yellow bright new growthNew leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?

Day 49 yellow leavesIs it normal for the leaves to turn this yellow with burnt tips at day 49 of flower. I cut the nutrients about 4 days ago and the leaves have yellow out for the pure kush this much but not really for the Dos Si Dos 33. The pure kush also looks like it has at least 3 weeks to go?

Maybe nutrient burn or?My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe it’s just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back up

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?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.
