I've read that it's a boron deficiency, but I'd rather be sure.

First photo mechanical damage to stick from wind and brushing. Second - clawing leaves, nitrogen toxicity. Slow down with food ! Less is more in weed growing. Golden rule !

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Bruising or nute problem?
I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.

Is this Phosphorous deficiency or overfeeding?
It happened from day to night, the watering with Fish-Mix and Bio-Heaven was made days ago. Otherwise, I haven´t feed her any bloom nutes yet. Peace ✌️

Is this really a potassium defiency? Any suggestions how to deal with it?
Hey Guys, need your help please. It's FD 28 and the leaves of my three White Widows show some signs of a nutrient deficiency (at least my assumption).I'm growing in living soil w/o any additional fertilizer and watering with a 7:3 mix of osmose/tap water and 0,5 ml/l CalMag.

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Brown spotting?
Hey everyone! My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean? I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.
