Magnesium deficiency?
FireManPanstarted grow question 4 years ago
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?

Hey,
Looking at your grow,
The symptoms reflect a calcium deficiency. Magnesium would likely progress from the middle of the leaf outwards, calcium, from the tips inwards with spotting. If you havent added any source of calcium then you may need some. if you have added some, low ph is usually to blame as calcium has trouble being absorbed by the plant at lower ph.
Hope this helps

Also if your leaves are yellow, it's most likely Nitrogen at this stage of growth, they don't look too bad to me tho mate.

I wouldn't go adding anything unless you are sure. If you think you have a deficiency research the symptoms. If you add something after a guess, chances are your guess may be wrong and you'll create the opposite of what you feared, an excess. Too much is just as bad as not enough.

Something like this chart should be your first go to with any deficiency fears. Look to the leaves. Look to the chart.
Hope this helps buddy!

Discolored Older Fan LeafI’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?

problems with low leavesin the lower part of the plant some leaves are yellowing, others are drying out and even detaching.
can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Yellow spots on leavesHi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?

Yellowing leaves. Zinc/Nitrogen deficiency?My plant has slight yellowing on the leaves and discoloration and I don't know the exact cause, from research to me it looks like zinc or nitrogen deficiency? I don't think it's too close to my light (last picture).
Can anyone help?

Nitrogen Deficiency?Think I might have a Nitrogen Deficiency but just wanted to check and confirm with some of you? Leaves are slightly pale and yellow across the plant. I checked runoff Ph last week and it was 6.1 realised it can lockout some calcium so flushed with 6.7. Thanks

Rapid yellowing of some leavesI've noticed strong yellowing of some leaves overnight. It usually happens to the lower leaves, but in my case the whole plant is pretty flat, so there's no real distinction between lower and upper leaves. Is that just flowers taking up nutes from lower leaves or some deficiency?

Leaves turning yellow/pointing up, stem turning purpleHaving a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!5 years ago

Strange coloured fan leaves (3) on one of my 4 plants, maybe some sort of deficiency? Thanks people!Hey there smart people! I have about 3 strange coloured fan leaves on one of my 4 plants and I’m not really sure what to make of it. To me it doesn’t look like any deficiencies that I came across per say. All other leaves look nice and healthy. Kinda randomly scattered. THX!
