You do not have a diary so we are guessing based on one photo. It could be a magnesium deficiency.

I am on day 53, I know it’s normal for plants to yellow later in flower, mine turn yellow very early like week 7. Some people way later and theirs are still very green. I recalibrated my ph pen week 6. Happened in under feeding too. Makes bud look awful. What am I doing wrong??

Probably a little over fed with N? I laready flushed her, at the moment she is in the 6th week, I'm using bio bizz with the suggested dose by the producer, but in 1,5L of water. What do you think?

The leafs started to look yellow in the middle when I checked on them today. They looked fine to me yesterday so I guess this happened in the past 24-48 hours, not sure why. It can be seen on Day 12 pictures. Is this normal or I should be worried?

The leaves are still curling downwards and inwards. This usually happens once the leaves become older. Although I've searched for the cause of the problem, I still don't understand what's wrong.

Yesterday i see new yellow leaves (plant 2). I have just checked them again and on the second plant the two small leaves are now brownish. What could that be? I water every two days and the soil is not wet but slightly moist. The other plant 1 grows wonderfully.

Hi all! I was checking on my plants and noticed one of them is showing yellow/brown spots in some the top leaves, only showing on 1 plant but I’m nervous it’s leaf septoria?? The plant is in week 10 and is my last pic on week 10 diary. Does anyone know what this could be? :)

Hey guys, I have noticed that some of the upper leaves are turning yellow. I read that it may be because of heat stress or light burn but I'm not entirely sure and just wanted to ask what i can do to stop other leaves from having this issue. Anyways, what do you guys think?

Hi, So all my leaves are pretty much curling under, and I have a couple leaves showing what looks like magnesium deficiency. I'm worried. Is this for sure nitrogen toxicity and will that cause the magnesium deficiency? What should I do?

leave edges curling down (newer growth), plant feels weak/limp, leaves feel papery. Only one of the two plants. maybe she is root bound? i believe my watering is okay. maybe a PH problem or nutrient deficiency? temps sit at abt 28. not enough circulation or high humidity? IDK....

Noticed a little yellowing on one of her leaf tips today on the main cola. Shouldn't have any deficiency at this point as I've only just started to flush. Is this the beggining of her fade?

I have lots of yellowing on the lower leaves of one plant. After reaserching I think it’s a nitrogen deficiency. Also today I’ve noticed lots of teeny tiny white/clear bugs! I’m super anxious about it, thinking my plants are goners. Any idea on what they are?

Any ideas to what might be causing these leaves to yellow/die? Only reasons I can think of are nutrient lockout, having the lights too close (although I've heard with CFLs theres pretty much no such thing as too close) or possible having the heater running, or constant fan air

Hi, can someone look at my picture called F57? Are those yellowish parts 'nanners'? They sure look like it. And if so, what does this mean?

It has a a few leaves curling down and they look drier than the rest, something I need to be worried about? I only used organic nutrients, earthworm humus when preflower started (don't know english name... vermicompost?) each week, watered with banana peals tea every 3 or 4 dys

The plants colors look healthy and about 8 flowering sites appearing on NL and 3 on WW. However, the leaves, particularly on the NL look to curl under. I've been having little trouble keeping the pH in the 5.5 - 6.5 range, seems to drop to the mid 4s daily, but fix quickly.
