answered grow question 6y ago
If they came off towards the bottom of the plant, it is a nitrogen deficiency. If not, since the yellowing and necrosis begins on the outward edges, I would say it looks like a Magnesium deficiency.

Can't deal with yellowing leaves in 4th week of flowering
Been having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?

Problem in my cultures and I can't find what they have.
hello, I have a problem on all my crops at the moment I can't understand all this could come.the last time I put RQS easy boost fertilizer in a seedbed. I water them as soon as the top soil is dry. I added bio nova X-cel 5ml/10l to my water. I really can't understand the symptoms

Fellow growers, after a few weeks of beautifull growth, I now start to get yellowing leaves which dry up and starve. I am. I am doubting between a lack of nutrification or over nutrification. I suspect the latter (biocanna nutrients and soil). Any ideas? Thanks!!

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Leaves curl up and yellowing
Beginner question, as usual (first time growing anything in my life tbh). My 2 plants don't look too healthy, especially one of them. Leaves curl up and yellowing (or not, I am not sure). What am I missing? Thanks!

Nutrient & critter problems need 1-2weeks from harvest need advice
The plant is a couple weeks of harvest but has some issues. (Some kind of nutrient lockout or deficiency can't tell what tho, pH is fine at about 5.8) And I got these annoying critters that seem to live on the soil (but aren't touching the plant) Any ideas on what to do ? :/

Sligthtly Yellow Leaves
I'm growing 2 Mephisto Canna Cheese seeds. Canna #1 is looking very healthy and green. Canna #2 is healthy (ish) but its branches are more spread out and the leaves are a bit yellow green. I'm trying to figure out if I have a problem with Canna #2 before it gets worse.

Hi. What is it missing? Is it a lack of potassium and phosphorus? or rather due to weather or old age. This is an older leaf from the middle part of the plant

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC
