Yellow/Brownish colored tips of leaves.
So, my girl now is 11 days old, while i was looking at here i noticed that the tips of the second pair of true leaves is soightly yellow/brownish colored, im worried for my plant. Could it be a wind burn ? I have a ventilator in my tent which was blowing at here. I moved it now.

Yellowing and brown spots on leaves
Can anyone identify why this is happening? I am growing 2 other plants (one the same strain) with identical treatment and this started happening with one of my Royal Jacks. Everyday new leafs show the same symptoms.

Why do the leaves of my plants have brown spots?
Why do the leaves of my plants have brown spots? I have control over all cultivation parameters except for humidity, which has been difficult for me to control and is currently high. What do you think?

Hi everyone. I am rdwc w/4 plants near end of flower. This plant has always been unhealthy. However this is a new twist. As I said rdwc, other girl are groovy, so it is what it is but my question is; what is it? Genetics?

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Tiny Brown/Bronze spots
My Dr. Lemon plant has a few orange/bronze spots on some of the middle/upper leaves, Looks like a calcium deficiency, but I'm not sure. Anybody have an idea of what this could be? Feel free to check out my diary on her for more context!

could this be due to the PH being too low?
I watered 3 days ago with PH 6.3 Ruoff was 6.0 today watered with PH 6.6 runoff was 6.1 Can the brown spots come from the wrong PH ? fertilizer is full BIO BIZZ CHEEMA, worm humus and mycoriza what would you recommend to do ?

Light burn?
I had lowered my Sanlight Q4 from 50 cm to 40cm, as per vendors recommendation and now I believe that I have burned the little ones. Or is this a nutrient issue?

Aeroponics system; fan leaves start browning on edge in 2nd week of bloom.
Aeroponics system that my fan leaves start browning on edge in 2nd week of bloom every time (about 7 grows in journey). Is this normal? Should i be concerned and adjust nutes at all? Or just selective trim any of the more "crispy" ones? Photo is 2nd-3rd week into bloom.
