If its just the lower leaves it may be from getting them wet when watering.

Some new leaves are getting yellow/weird. Do I need to worry?
Hi guys, from today some of new leaves are growing like this. Is everything regular or is it a sign of something wrong? Given my inexperience I don't understand the symptoms from the leaves. Info: DWC - 42 days from germination - PH 6.0-6.4 - EC 1.5 - Temp: 29 - RH 60%

Should I worry?
A couple days after flipping to 12/12… I see yellow edges to new leaves. Should I worry? Wait a bit and see? The other plant looks fine and they’re both getting same nutes.

turned yellow, what's the problem?
The big burdock at the root started to turn yellow a couple of days ago, the tip is drying and bending. This is a deficiency of phosphorus and potassium on the 45th day from the nut (7th week) - or am I wrong? How to fix it?

Brown leaves and red stems. Is this a calcium deficiency ?
I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!

Yellow lower leaves
Hello, This is my first grow and now I'm confronted with the first problem. The lower leaves on my plants are turning bright and yellow. A few leaves have very small brown spots. Can someone help me and perhaps have an idea as to how I should proceed? Thanks.

Critical Purple: Leaves slightly yellow.
Just started my first grow. I1 placed the light high in the tent and the leaves slightly turned yellow. I lowered it yesterday to 18” over the top on the plants. Just wondering if I am on the right track to solve the issue. The plants are still growing. Minimal nutrients 1ml/gal.

Yellowing new growth!?
New growth is yellowing is this nitrogen deficiency? And it’s only happening to this strain. Also growth in general has slowed. Temps. Have been getting down to about 66-67F Bc of the cold front that came through.

To Nute or Not?
About to hit two weeks. Growth has been steady, but slow. In lambert's cactus/succ. mix. I want them to be in a bigger pot and different soil, but they seem too little to transfer atm. Do they look like they're starting to lacking nutes? Did suffer some light/heat :(
