answered grow question 5y ago
From the looks of it, it looks like a leaf dying from not getting enough light which is completely normal. Hopefully, I answered your question and remember " Happy Growing".

Bottom leaves yellowing at beginning of flower
So my plants have been flowering for about a week now and the lower fan leaves are yellowing with brown spots. Should I be feeding them more of the flower girl I’m using or is this a deficiency of a specific nutrient? (following dr earth feeding schedule designed for cannabis)

Is this nute or sun burn? What should I do to save my babies ?
I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?

What is this rust discoloration on leaves, and how can I stop it?
Does anyone happen to know what is causing this rust colored discoloration on fan leaves? It starts on bottom leaves, and moves up. Also seeing yellowing on leaves, and not sure if its pest issue, light issue, deficiency, or watering concern. Super nervous plants are dying🙁

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!

I have tried to figure out what this could be without much luck... it seems that my leaves are having a slightly yellow tint to them under the grow light. Under normal light it seems ok, what could this be? Overwatering I am guessing but not sure.. Any help would be appreciated

From previous post just some more infon on what I feed and how, on a 12
So I use 5 ML per gallon of fox farm Grow Big Liquid Plant Food, And 5 ML Per Gallon Of Fox Farm Buds And Blooms Fertilizer. I'm barely staring to Introduce Cal-Mag so I don't think the Cal-Mag is causing the issue, I water every 2-3 Days. Temp is Right Around 80 during the day 7

Hi, what's going on with my queen? It's an auto gorilla cookie that I transplanted about one 1 week ago. From 1 to 3 gallon. I use gold label premium mix. Thinking maybe it's a to strong blend? Appreciate all answers, thanks! (It has recovered and grown since transplant)

Leaves bright green
So I have ruled out the fact that this is not a ph problem, have been properly watering at a consistent ph of 6.5, tested the run off today and it's at a pH of 6.4, also there is purple stems and the main stock has purple running through it as well?!?! Is this lack of pk? ca/mg?

Is this magnesium deficiency?
After some googling, it seems to match? But the yellowing on mine seems to be very concentrated just on the tips.

Lower leaves yellowing and wilting quickly
Soooo Just went to water this beautiful lady and as you can see from the pictures 2 days ago and she was healthy. So this evening i found that the lower large fan leaves and the smaller fan leaves on bud sites are drooping and yellowing. This looks like its nitrogen or lockout?

Yellow Leaves Normal?
Hi Everyone! I’m just starting week 7 with my RQS fat bananas and northern light. All autos. RQS state harvest in 9-10 weeks. All the girls have 3-6 low level fan leaves going very yellow. I assume this is fine but I’d love some feedback. It’s my first grow.
