That looks like a nutrient/water spillage burn. If there is residue left on the leaves, the light will magnify it and "burn" it. Could be calcium too. Is it on the lower or middle leaves? Are they any leaves wilting or dying at the base of the plant? Have you recently fed a high dose of phosphorus?

Ph perfect nutes doesn't mean you dont have to check to make sure your ph is correct going into the planter or the ph coming out of the planter. Really just helps stabilize the ph. You still need a ph and tds reader to make sure your ph and ec are correct going in and coming out the bottom. To me the spots look ph related. Cheers

No, this is damage caused by splashing fertilizer on the leaves while the lights are on.

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??

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?

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?

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?

Is it possible that maybe I underfed my plant and that's causing my actual problem? Is it something normal? Or there's something else going on with it that I should check and fix fast? In general the plant has a lighter green color and old leaves are getting yellow. Thanks!

Super soil growers ever come across any deficiencies? See a couple lower fan leaves I removed today. I'm sure leaf loss to some extent is natural, but I read that the lower leaves are your indicators, so I wanted to run these by yall to see if you suspect and deficiencies

On the 31st day I noticed that, in both the plants, the leaves started yellowing from the bottom of the plant! For now the yellowing reached the first couple of fan leaves. You can see that in last three photos. Could be some pH issue or some over/under feeding?

One of my plants fans are yellowing, spotting, pretty badly. The medium PH is 6.5, same as my other plants, but she just doesn’t seem to be liking it. I’m using nutrients, but not heavily. About a quarter teaspoon per gallon of the flora trio. It’s the mid fans not bottom or new.
